t . lain, lessening the distance to the city, and this path was a great favorite with the postman, as it made his journey so much the shorter. Going one day as usual to Kyoto, he reached the field a little later than was his wont, and night came on before he had ad- vanced very far. Without a light or the means of procuring one,, he wandered aimlesslj^ on for a while, but finally seeing that he had missed the path in the darkness, resolved to pass the night where he was, with the sky for a coverlet. Without giving a second thought to all the ugly stories told of the field, the ghosts and malicious fox-sprites said to hold their nightly revels in that spot, the postman bravely determined to make the best of it, and * This tale was first translated from the Japanese into German, and read, among others, before the Gesellsehaft fur Volkerkunde in Ost-Asien, in Yokohama, by F.

Drawing nearer, he found that it was a sort of watch-house, such as the peasants build near the rice-fields in order to protect the growing grain. Overjoyed at having found even this poor shelter, the postman entered the little hut, and, throwing himself on a heap of dried grass, was soon fast asleep. Perfect silence reigned over the sterile plain ; only now and again the far-off hoot of an owl or the mournful cry of some night bird broke the stillness of the night. Several hours had passed, when the sleeper was suddenly awak- ened by the deep, sonorous note of a bell. The sound seemed to come from the western portion of the field, and all at once the startled sleeper heard a tramping as of many feet, and a confused murmur of Buddhist chants and prayers. Nearer and nearer came the crowd of people, to the listener's great astonishment. *' There are no houses in the field," thought he, " and anyhow no one would think of going at midnight to such a deserted and ill- omened spot." The stars were shining brightly, but no moon illumined the scene, so that the trembling postman could only see •objects very near him. Nevertheless he peeped cautiously out of his hiding place and saw, to his unbounded surprise, a long pro- cession of men bearing torches and lanterns. In front of all inarched a tall jjriest, reciting the Buddhist invocation, NaTiiu Amida Butsu, in a clear, loud voice. " It is a funeral procession ! " thought the frightened listener, and crept farther back into the shadows of the hut. As soon as the mournful procession had reached the little hut a halt was made, and tlie cofiin-bearers stej^ped forward. Scarcely five paces from the hut the grave was dug, and the coffin placed in it. The priest then threw the earth back into the grave and built a little mound above it, and finally placed a few sticks cov- ered with Buddhist characters in one end of the mound. With- out further word the somber procession turned back, and moved slowly away in the same solemn and impressive manner, leaving the postman in a most pitiable frame of mind. It was quite bad enough to be compelled to spend the night in such an uncanny and grewsome spot ; but the late hour, mysterious burial, and the proximity of the freshly dug grave were enough to frighten the bravest heart. As if chained to the spot by some evil spell, the postman kept staring at the little mound before him. Suddenly, while he was gazing fixedly at the grave, it began to rock slowly from side to side. Quicker and quicker became the rocking, while the invol- untary spectator underwent an agony of terror. Faster and faster still rocked the mound, until it fell over with a great shock, and a naked, horrid thing jumped from the grave and ran toward the i6 THE POPULAR SCIENCE MONTHLY. postman. In an instant he remembered that horrible ghouls always attend a burial, and that these ghouls often kill and eat living beings. There was no time to lose, for the creature had already reached the entrance of the hut. Crazed with fear, the postman drew hisiswovd and made one desperate cut at his enemy, and then, without daring to give a second blow, ran out of the hut and into the night. Hours seemed to have passed before the postman arrived, half dead with exhaustion and panting for breath, at the house of a JAPANESE HOME LIFE. 17 peasant, just "beyond the outskirts of the field. He knocked again and again, but no one came in answer, and so he had to wait for the day to dawn. Shortly after sunrise the people of the house arose, and, hearing the knocking, took the still breathless wan- derer into the guest chamber, where they attended to his pitiable state, and then begged him to relate what had befallen him. This he did, and the peasants at once determined to go to the little hut in the field of Inami, which was well known to them. Upon arriving at the spot they found no signs of a burial or of a grave. Mound and coffin had utterly disappeared ; but just in front of the hut lay the body of a huge badger, killed by the one cut of the good steel. At once they saw what had happened. The evil beast had wished to frighten the belated wanderer ; and the funeral procession and priest, coffin, and grave had been merely the work of magic. So much for the stories that play such an important role in the drama of home life in Japan. It is to be regretted that this subject has not been more extensively dealt with in recent writ- ings of the country, for many of the hidden beauties of the coun- try and people are best portrayed in the stories of bygone heroes, as told to the children around the hibachi, or as sung by some graceful maiden with samisen or Icoto accompaniment ; while the tales of ghosts or ghouls rival those of almost any other land in variety and horror. Turning to the pastimes common to Japanese homes, a brief mention of the most popular games must not be omitted. Oo and sJiogi are similar to our games of draughts and chess, yet the for- mer is far more scientific than checkers. There are several games of cards, the playing cards being about as long as those used in this country, but scarcely three quarters of an inch wide. Another favorite game is that of " One Hundred Poems." It is somewhat similar to our rather childish game of " Authors," with the excep- tion that the Japanese game is by no means childish, and requires an intimate knowledge of at least one hundred poems of well- known merit. Two hundred cards are used in the game, and half a poem is written on each card. The cards being spread before the players, the half of a poem on any one card is read, and the other half searched for by the contestants. Then the different seasons of the year have typical games. The most picturesque of these is haguita, or " battledoor and shuttlecock," which is exclu- sively a New- Year's game. Then the time of the cherry blooms brings its games beneath the bloom-laden branches. Music and song find their way into the homes of Japan far more extensively than in this country. To be sure, the music of either koto or samisen is apt to sound strange, and at first perhaps almost unin- VOL. XLIII. 2 l8 THE POPULAR SCIENCE MONTHLY tellig'ible, to our untutored ears; but we soon become familiar witli the plaintive notes of tlie Icoto or the sonorous vibrations of the samisen, and learn to both recognize and appreciate the quaint minor harmonies and softly worded melody of some love song, or so-fu-ren. As I have already had occasion to mention, the dramatic or operatic poems are sung with the accompaniment of the samisen, while the historical poems, or utai, find a musical accompaniment only when recited on the no stage, and then flute and drums are the instruments used. The dramatization of the utai upon the no stages is a very ancient custom, and can only be appreciated by the better educated classes. Correctly speaking, no is a liis- Facsimile of a Poem by Aritsunb torical dance, full of weird mysticisms almost unintelligible to those not conversant with its meaning, but its proper performance is a classic art. It has remained unchanged in the slightest detail for centuries, and through its medium the classic historical poetry of the nation is retained and placed before the appreciative public of the higher class. Thus the drama and history of the country, so full of heroism and romance, shape themselves into poetry and song. The blend- ing of art with poetry is another feature typical of the Japanese people. There are two purely Jajjanese schools of art : the one dealing with the minutest details, and the other with the bold and forcible portrayal of impressions and suggestions, rather than details ; graceful sketches, rather than detailed drawings. " We JAPANESE HOME LIFE. ig can not reproduce Nature in art/' a Japanese artist has said, "and instead of making so bold an attempt, had best satisfy ourselves with mere suggestions of Nature's beauties." The same may be said of some Japanese poetry, for the ida, or sonnets, usually are mere poetic suggestions of a deeper meaning or sentiment. This brings one to a realization of the close connection between art and poetry in Japan, as also between poetry and music. In social gatherings among friends, a favorite mode for mutual entertain- ment is for one of the guests to quickly sketch some passing thought or memory of one of Nature's beauties ; it may be the crest of some distant mountain, a branch heavy with blossoms, or a flower. This sketch is then passed on to another guest, who, in looking at it, seeks to find some poetic suggestion, or hidden lesson, and having done so, adds the verse to the sketch, and the picture is complete. These illustrated sonnets, the fruits of poetic inspiration and artistic impression, are taken home, to be preserved as cherished souvenirs of the evening's entertain- ment. To illustrate this more clearly, we will say that an artist has, with two or three rough strokes of his brush, depicted a bleak mountain peak, with a flock of birds flying above it. This is passed to Aritsun^, a Japanese poet of recognized merit, who after a few moments' thought adds a sonnet to the sketch. It is, like the sketch, a mere suggestion of a deeper sentiment, or imi, as the Japanese would have it. I can best render it as follows, making the translation as literal as possible : We may struggle to the peak Of the mountaio, bare and bleak, There but to learn, And well discern, That the winging birds above, Speeding to their nests of love, More of Nature's beauties see Far than we. Surely the beauty of the thought is evident, and the deeper meaning, or imi, appreciable even to the prosiest of us. Yet in rendering the lesson of the sonnet, as implied to the Japanese reader of the above words, I might- add the following lines : So, when striving naught but fame to obtain. Thou chance mayst reach the highest peak of earthly gain; Then thou wilt learn, And well discern. That Nature doth her beauties wide outspread For those to daily duties who are wed. While simple lives yield peace and light. Fame blinds the sight. 20 THE POPULAR SCIENCE MONTHLY. One more example of this variety of illustrated verse will suf- fice, and in the one I have chosen the meaning is confessedly obscure, or at least deep enough to require some thought. The picture, or sketch, is one of a bunch of wild flowers (chrysanthe- mums), which make their first appearance during the closing days of September, by which time, also, the cheery voice of the locust has been hushed by the increasing cold of the autumn : Though September's last days are fast ebbing away, And the locust's bright sonnet is stilled, Yet the wild flowers fair breathe a far sweeter song While the air with their fragrance is filled. In justice it must be confessed that the imi of the above lines is rather vague, but may be regarded as a reminder of Nature's kind compensation, for, with the change of seasons, one beauty is Facsimile of an Uta, or Sonnet scarcely missed before another has filled its place. Perhaps the words may be construed as a gentle reproof to discontented spir- its. That the very heart of the nation finds its voice in song is quite evident, for in every instance where a sonnet or poem would find application we are sure to find one. During the time of the cherry and plum blossoms, in early spring, the bloom-laden branches are further ornamented by numerous sonnets inspired by the beauty of the scene — written on strips of white paper, and then made fast to the low-hanging branches. Indeed, the poetic enthusiasm of a score of Orlandos in the forests of Arden would be put to shame. Every season of the year, with the flowers that THE INADEQUACY OF ''NATURAL SELECTION:' 21 it brings, is praised in verse. From the chrysanthemums in autumn, the camellias and plum blossoms of the winter months, the cherry and peach blossoms and wistaria during early spring, the peony in May, and the great lotus flowers during the summer months, so every season has its typical flower, and every flower is loved and praised in song and sonnet by the people. There is room for flowers in the humblest abode, and even the crests of the thatch-roofed huts of the farmers are transformed into miniature gardens of hyacinths and tulips. So we have pushed aside the latticed doors and glanced in at the Japanese home. True, our stay has been short, and much must be left unnoticed ; yet, as we take our reluctant leave, above the soft melody of the A-o/o strings, we can clearly hear the lusty chirp of the " cricket on the hearth." THE IX ADEQUACY OF " NATURAL SELECTION. . •'• By HERBERT SPENCER. *i ' ALONG with that inadequacy of natural section to explain' changes of structure which do not aid life in important ways, alleged in § 166 of The Principles of Biology, a further in- adequacy was alleged. It was contended that the relative powers of co-operative parts can not be adjusted solely by survival of the fittest ; and especially where the parts are numerous and the co- operation complex. In illustration it was pointed out that im- mensely developed horns, such as those of the extinct Irish elk, weighing over a hundredweight, could not, with the massive skull bearing them, be carried at the extremity of the outstretched neck without many and great modifications of adjacent bones and muscles of the neck and thorax ; and that without strengthening of the fore-legs, too, there would be failure alike in fighting and in locomotion. And it was argued that while we can not assume spontaneous increase of all these parts proportionate to the ad- ditional strains, we can not suppose them to increase by variation one at once, without supposing the creature to be disadvantaged by the weight and nutrition of parts that were for the time use- less—parts, moreover, which would revert to their original sizes before the other needful variations occurred. When, in reply to me, it was contended that co-operative parts vary together, I named facts conflicting with this assertion— the fact that the blind crabs of the Kentucky caves have lost their eyes but not the foot-stalks carrying them ; the fact that the nor- mal proportion between tongue and beak in certain selected varie- ties of pigeons is lost ; the fact that lack of concomitance in de- 22 THE POPULAR SCIENCE MONTHLY. crease of jaws and teeth in snndry kinds of pet dogs, has caused great crowding of the teeth (The Factors of Organic Evolution, pp. 12, 13). And I then argued that if co-operative parts, small in number and so closely associated as these are, do not vary to- gether, it is unwarrantable to allege that co-operative parts which are very numerous and remote from one another vary together. After making this rejoinder I enforced my argument by a further example— that of the giraffe. Tacitly recognizing the truth that the unusual structure of this creature must have been, in its more conspicuous traits, the result of survival of the fittest (since it is absurd to suppose that efforts to reach a high branch could lengthen the legs), I illustrated afresh the obstacles to co-adapta- tion. Not dwelling on the objection that increase of any com- ponents of the fore-quarters out of adjustment to the others would cause evil rather than good, I went on to argue that the co-adapta- tion of parts required to make the giraffe's structure useful, is much greater than at first appears. This animal has a grotesque gallop, necessitated by the great difference in length between the fore and the hind limbs. I pointed out that the mode of action of the hind limbs shows that the bones and muscles have all been changed in their proportions and adjustments; and I contended that, difficult as it is to believe that all parts of the fore-quarters have been co-adapted by the appropriate variations now of this part, now of that, it becomes impossible to believe that all the parts in the hind-quarters have been simultaneously co-adapted to one another and to all the parts of the fore-quarters : adding that want of co-adaptation, even in a single muscle, would cause fatal results when high speed had to be maintained while escaping from an enemy. Since this argument, repeated with this fresh illustration, was published in 1886, I have met with nothing to be called a reply ; and might, I think, if convictions usually followed proofs, leave the matter as it stands. It is true that, in his Darwinism, Mr. Wallace has adverted to my renewed objection and, as already said, contended that changes such as those instanced can be effected by natural selection, since such changes can be effected by artificial selection : a contention which, as I have pointed out, assumes a parallelism that does not exist. But now, instead of pursuing the argument further along the same line, let me take a somewhat different line. If there occurs some change in an organ, say, by increase of its size, which adapts it better to the creature's needs, it is ad- mitted that when, as commonly happens, the use of the organ demands the co-operation of other organs, the change in it will generally be of no service unless the co-operative organs are changed. If, for instance, there takes place such a modification THE INADEQUACY OF ''NATURAL SELECTION:' 23 of a rodent's tail as that which, by successive increases, produces the trowel-shaped tail of the beaver, no advantage will be derived unless there also take place certain modifications in the bulks and shapes of the adjacent vertebrae and their attached muscles, as well, probably, as in the hind limbs, enabling them to withstand the reactions of the blows given by the tail. And the question is, by what process these many parts, changed in different degrees, are co-adapted to the new requirements — whether variation and natural selection alone can effect the readjustment. There are three conceivable ways in which the parts may simultaneously change: (1) they may all increase or decrease together in like degrees ; (2) they may all simultaneously increase or decrease in- dependently, so as not to maintain their previous proportions or assume any other special proportions ; (3) they may vary in such ways and degrees as to make them jointly serviceable for the new end. Let us consider closely these several conceivabilities. And first of all, what are we to understand by co-operative parts ? In a general sense, all the organs of the body are co- operative parts, and are respectively liable to be more or less changed by change in any one. In a narrower sense, more directly relevant to the argument, we may, if we choose to multiply diffi- culties, take the entire framework of bones and muscles as formed of co-operative parts ; for these are so related that any consider- able change in the actions of some entails change in the actions of most others. It needs only to observe how, when putting out an effort, there goes, along with a deep breath, an expansion of the chest and a bracing up of the abdomen, to see that various muscles beyond those directly concerned are strained along with them. Or, when suffering from lumbago, an effort to lift a chair will cause an acute consciousness that not the arms only are brought into action, but also the muscles of the back. These cases show how the motor organs are so tied together that altered actions of some implicate others quite remote from them. But without using the advantage which this interpretation of the words would give, let us take as co-operative organs those which are obviously such — the organs of locomotion. What, then, shall we say of the fore and hind limbs of terrestrial mammals, which co-operate closely and perpetually ? Do they vary together ? If so, how have there been produced such contrasted structures as that of the kangaroo, with its large hind limbs and small fore limbs, and that of the giraffe, in which the hind limbs are small and the fore limbs large — how does it happen that, descending from the same primitive mammal, these creatures have diverged in the proportions of their limbs in opposite directions ? Take, again, the articulate animals. Compare one of the lower types, with its rows of almost equal-sized limbs, and one of the higher 24 THE POPULAR SCIENCE MONTHLY. types, as a crab or a lobster, with limbs some very small and some very large. How came this contrast to arise in the course of evo- lution, if there was the equality of variation supposed ? But now let us narrow the meaning of the phrase still further ; giving it a more favorable interpretation. Instead of considering separate limbs as co-operative, let us consider the component parts of the same limb as co-operative, and ask what would result from varying together. It would in that case happen that, though the fore and liind limbs of a mammal might become different in their sizes, they would not become different in their structures. If so, how have there arisen the unlikeness between the hind legs of the kangaroo and those of the elephant ? Or if this comparison is objected to, because the creatures belong to the widely different divisions of implacental and placental mammals, take the cases of the rabbit and the elephant, both belonging to the last division. On the hypothesis of evolution these are both derived from the same original form, but the proportions of the parts have become so widely unlike that the corresponding joints are scarcely recog- nized as such by the unobservant: at what seem corresponding places the legs bend in opposite ways. Equally marked, or more marked, is the parallel fact among the Articulata. Take that limb of the lobster which bears the claw and compare it with the cor- responding limb in an inferior articulate animal, or the corre- sponding limb of its near ally, the crayfish, and it becomes obvious that the component segments of the limb have come to bear to one another in the one case proportions immensely different from those they bear in the other case. Undeniably, then, on contemplating the general facts of organic structure, we see that the concomitant variations in the parts of limbs have not been of a kind to produce equal amounts of change in them, but quite the opposite — have been everywhere producing inequalities. Moreover, we are re- minded that this production of inequalities among co-operative parts, is an essential principle of development. Had it not been so, there could not have been that progress from homogeneity of structure to heterogeneity of structure which constitutes evolution. We pass now to the second supposition : — that the variations in co-operative parts occur irregularly, or in such independent ways that they bear no definite relations to one another — miscel- laneously, let us say. This is the supposition which best corre- sponds with the facts. Glances at the faces around yield conspic- uous proofs. Many of the muscles of the face and some of the bones, are distinctly co-operative ; and these respectively vary in such ways as to produce in each person a different combination. What we see in the face we have reason to believe holds in the limbs as in all other parts. Indeed, it needs but to compare people whose arms are of the same lengths, and observe how stumpy are THE INADEQUACY OF ''NATURAL SELECTION:' 25 the fingers of one and how slender those of another ; or it needs but to note the unlikeness of gait of passers-by, implying small nnlikenesses of structure; to be convinced that the relations among the variations of co-operative parts are anything but fixed. And now, confining our attention to limbs, let us consider what must happen if, by variations taking place miscellaneously, limbs have to be partially changed from fitness for one function to fitness for another function — have to be re-adapted. That the reader may fully comprehend the argument, he must here have patience while a good many anatomical details are set down. Let us suppose a species of quadruped of which the members have for long past periods been accustomed to locomotion over a relatively even surface, as, for instance, the "prairie dogs" of North America ; and let us suppose that increase of numbers has driven part of them into a region full of obstacles to easy locomo- tion — covered, say, by the decaying stems of fallen trees, such as one sees in portions of primeval forest. Ability to leap must be- come a useful trait ; and, according to the hypothesis we are con- sidering, this ability will be produced by the selection of favor- able variations. What are the variations required ? A leap is effected chiefly by the bending of the hind limbs so as to make sharp angles at the joints, and then suddenly straightening them ; as any one may see on watching a cat leap on to the table. The first required change, then, is increase of the large extensor mus- cles, by which the hind limbs are straightened. Their increases must be duly proportioned, for if those which straighten one joint become much stronger than those which straighten the other joint, the result must be collapse of the other joint when the muscles are contracted together. But let us make a large admission, and suppose these muscles to vary together; what further muscular change is next required ? In a plantigrade mammal the metatarsal bones chiefly bear the reaction of the leap, though the toes may have a share. In a digitigrade mam- mal, however, the toes form almost exclusively the fulcrum, and if they are to bear the reaction of a higher leap, the flexor mus- cles which depress and bend them must be proportionately en- larged ; if not, the leap will fail from want of a firm point d'appvi. Tendons as well as muscles must be modified ; and, among others, the many tendons which go to the digits and their phalanges. Stronger muscles and tendons imply greater strains on the joints ; and unless these are strengthened, one or other dislocation will be caused by a more powerful spring. Not only the articulations themselves must be so modified as to bear greater stress, but also the numerous ligaments which hold the parts of each in place. Nor can the bodies of the bones remain unstrengthened ; for if they have no more than the strengths needed for previous move- 26 THE POPTLAR SCIENCE MONTHLY. meiits they will fail to bear more violent movements. Thus, say- ing nothing of the required changes in the pelvis as well as in the nerves and blood-vessels, there are, counting bones, muscles, ten- dons, ligaments, at least fifty different parts in each hind leg which have to be enlarged. Moreover, they have to be enlarged in unlike degrees. The muscles and tendons of the outer toes, for example, need not be added to so much as those of the median toes. Now, throughout their successive stages of growth, all these parts have to be kept fairly well balanced ; as any one may infer on remembering sundry of the accidents he has known. Among my own friends I could name one who, when playing lawn-tennis, sna])ped the Achilles tendon; another who, while swinging his children, tore some of the muscular fibers in the calf of his leg ; another who, in getting over a fence, tore a ligament of one knee. Such facts, joined with every one's experience of sprains, show that during the extreme exertions to which limbs are now and then subject, there is a giving way of parts not quite up to the required level of strength. How, then, is this balance to be maintained ? Suppose the extensor muscles have all varied appropriately ; their variations are useless unless the other co- operative parts have also varied appropriately. Worse than this. Saying nothing of the disadvantage caused by extra weight and cost of nutrition, they will be causes of mischief — causes of de- rangement to the rest by contracting with undue force. And then, how long will it take for the rest to be brought into adjust- ment ? As Mr. Darwin says concerning domestic animals : " Any particular variation would generally be lost by crossing, rever- sions etc., . . . unless carefully preserved by man." In a state of nature, then, favorable variations of these muscles would dis- appear again long before one or a few of the co-operative parts could be appropriately varied, much more before all of them could. With this insurmountable dilhculty goes a difficulty still more insurmountable — if the expression may be allowed. It is not a question of increased sizes of parts only, but of altered shapes of parts, too. A glance at the skeletons of mammals shows how un- like are the forms of the corresponding bones of their limbs ; and shows that they have been severally remolded in each species to the different requirements entailed by its different habits. The change from the structures of hind limbs fitted only for walking and trotting to hind limbs fitted also for leaping, implies, there- fore, that along with strengthenings of bones there must go alter- ations in their forms. Now the spontaneous alterations of form which may take place in any bone are countless. How long, then, will it be before there takes place that particular alteration which will make the bone fitter for its new action ? And what is the THE INADEQUACY OF ''NATURAL SELECTION:' 27 probability that the many required changes of shape, as well as of size, in bones will each of them be effected before all the others are lost again ? If the probabilities against success are incalcu- lable, when we take account only of changes in the size of parts, what shall we say of their incalculableness when differences of form also are taken into account ? " Surely this piling up of difficulties has gone far enough " ; the reader will be inclined to say. By no means. There is a difficulty immeasurably transcending those named. We havie thus far omitted the second half of the leap, and the provisions to be made for it. After ascent of the animal's body comes descent ; and the greater the force with which it is projected up, the greater is the force with which it comes down. Hence, if the supposed creature has undergone such changes in the hind limbs as will enable them to propel it to a greater height, without having undergone any changes in the fore limbs, the result will be that on its de- scent the fore limbs will give way, and it will come down on its nose. The fore limbs, then, have to be changed simultaneously with the hind. How changed ? Contrast the markedly bent hind limbs of a cat with its almost straight fore limbs, or contrast the silence of the upward spring on to the table with the thud which the fore paws make as it jumps off the table. See how unlike the actions of the hind and fore limbs are, and how unlike their structures. In what way, then, is the required co-adaptation to be effected ? Even were it a question of relative sizes onlj^, there would be no answer ; for facts already given show that we may not assume simultaneous increases of size to take place in the hind and fore limbs ; and, indeed, a glance at the various human races, which differ considerably in the ratios of their legs to their arms, shows us this. But it is not simply a question of sizes. To bear the increased shock of descent the fore limbs must be changed throughout in their structures. Like those in the hind limb, the changes must be of many parts in many proportions ; and they must be both in sizes and in shapes. More than this. The scapu- lar arch and its attached muscles must also be strengthened and remolded. See, then, the total requirements. We must suppose that by natural selection of miscellaneous variations, the parts of the hind limbs shall be co-adapted to one another, in sizes, shapes, and ratios ; that those of the fore limbs shall undergo co-adapta- tions similar in their complexity, but dissimilar in their kinds ; and that the two sets of co-adaptations shall be effected pari passu. If, as may be held, the probabilities are millions to one against the first set of changes being achieved, then it may be held that the probabilities are billions to one against the second being simultaneously achieved, in progressive adjustment to the first.^ 2 8 THE POPULAR SCIENCE MONTHLY. There remains only to notice the third conceivable mode of adjustment. It may be imagined that though, by the natural selection of miscellaneous variations, these adjustments can not be effected, they may nevertheless be made to take place appro- priately. How made ? To suppose them so made is to suppose that the prescribed end is somewhere recognized ; and that the changes are step by step simultaneously proportioned for achiev- ing it — is to suppose a designed production of these changes. In such case, then, we have to fall back in part upon the primi- tive hypothesis ; and if we do this in part, we may as well do it wholly — may as well avowedly return to the doctrine of special creation. What, then, is the only defensible interpretation ? If such modifications of structure produced by modifications of function as we see take place in each individual, are in any measure trans- missible to descendants, then all these co-adaptations, from the simplest up to the most complex, are accounted for. In some cases this inheritance of acquired characters suffices by itself to explain the facts ; and in other cases it suffices when taken in com- bination with the selection of favorable variations. An example of the first class is furnished by the change just considered ; and an example of the second class is furnished by the case before named of development in a deer's horns. If, by some extra mass- iveness spontaneously arising, or by formation of an additional " point," an advantage is gained either for attack or defense, then, if the increased muscularity and strengthened structure of the neck and thorax, which wielding of these somewhat heavier horns produces, are in a greater or less degree inherited, and in several successive generations, are by this process brought up to the re- quired extra strength, it becomes possible and advantageous for a further increase of the horns to take place, and a further increase in the apparatus for wielding them, and so on continuously. By such processes only, in which each part gains strength in propor- tion to function, can co-operative parts be kept in adjustment, and be readjusted to meet new requirements. Close contempla- tion of the facts impresses me more strongly than ever with the two alternatives — either there has been inheritance of acquired characters, or there has been no evolution. — Contemporary Review, [To be con eluded.

EVIDENCES OF GLACIAL MAN IN OHIO. 29 EVIDENCES OF GLACIAL MAN IN OHIO. By Prof. G. FREDERICK WRIGHT. THE recent sweeping denials by Mr. W. H. Holmes, of the Bureau of Ethnology, respecting the validity of the evidence upon which the existence of glacial man in America has been so generally accepted makes it necessary to present the facts in greater detail than has heretofore been done. It seems that Mr, Holmes has been himself looking for palaeolithic implements in undisturbed gravel of glacial age for two or three years, but has not found any ; and that he has discovered that the Indians had quarries and workshops in various places where they threw aside great piles of partially wrought and rejected implements which were of such shape as not to be readily available tor their pur- poses, and which had a faint resemblance to palceolithic imple- ments. In view of these experiences Mr. Holmes has come to the conclusion, first, that all the so-called palaeolithic implements which have been found by Dr. C. C. Abbott and others in America are simply " rejects ''; and, secondly, that nobody in America has found any implements in undisturbed gravel of glacial age. In Science for January 20, 1892, he uses the following language : " If there was, as is claimed, an ice-age man, or at any rate a pala:'0- lithic man, in eastern America, the evidence so far collected in support of these propositions is so unsatisfactory and in such a state of utter chaos that the investigation must practically begin anew.^' The best answer which I can give to this sweeping denial will be to present, with illustrations, the details concerning a single discovery in Ohio with which I am familiar, namely, that at New- comerstown. But, to get the full significance of this discovery, and the cumulative value of the evidence afforded by it, a brief statement of other discoveries must be made. The evidence naturally begins with that at Trenton, N. J., where Dr. C. C. Abbott has been so long at work. Dr. Abbott, it is true, is not a professional geologist, but his familiarity with the gravel at Trenton, where he resides, the exceptional oppor- tunities afforded to him for investigation, and the frequent visits of geologists have made him an expert whose opinion is of the highest value upon the question of the undisturbed character of the gravel deposit. The gravel banks which he has examined so long and so carefully have been extensively exposed by the undermining of floods on the river-side, but principally by the excavations which have been made by the railroad and by private parties in search of gravel. For years the railroads had been at work digging away the side of the banks until they had removed 30 THE POPULAR SCIENCE MONTHLY a great many acres of the gravel to a deptli of twenty or twenty- five feet. Any one can see that in such conditions there has been no chance for " creep " or landslides to have disturbed the strati- fication ; for the whole area was full of gravel, and there was no chance of disturbance by natural causes. Now, Dr. Abbott's tes- timony is that up to the year 1888 sixty of the four hundred palaeo- lithic implements which he had found at Trenton had been found at recorded depths in the gravel. Coming down to specifications, he describes in his reports the discovery of one (see Primitive Industry, page 493) found while watching the progress of an ex- Fio. 1. — Section of the Trenton Geavei., in which the Implements desckibed in the Text are found. The shelf on which the man stands is made in process of excavation. The gravel is the same above and below.

Another was found at the bluff at Trenton, in a narrow gorge where the material forming the sides of the chasm had not been displaced, under a large bowlder nine feet below the surface (ibid,, page 496). An- other was found in a perpendicular exposure of the bluff imme- diately after the detacdiment of a large mass of material, and in a surface that had l)ut the day before been exposed, and had not EVIDENCES OF GLACIAL MAN IX OHIO. 31 yet begun to crumble. The specimen was twenty-one feet from the surface of the ground. In all these and numerous other cases Dr. Abbott's attention was specially directed to the question of the undisturbed char- acter of the gravel, he having been cautioned upon this point in the early part of his investigations. Here it is proper to premise that the apparent monopoly of this evidence by Prof. Putnam and his associates in the Peabody Museum at Cambridge, Mass., has come about by a legitimate and natural process, which at the same time has probably inter- fered to a considerable extent with the general spread of the specific information in hand. Early in the investigations at Tren- ton, Prof. Putnam, who had lately become curator of the museum, with its large fund for prosecuting investigations, satisfied him- self of the genuineness of Dr. Abbott's discoveries, and at once retained him as an assistant in the work of the museum, thus diverting to Cambridge all his discoveries at Trenton. Living on the ground during long-continued and extensive excavations made by the railroad. Dr. Abbott's opportunities were exceptionally favorable ; hence his own prominence in the whole matter. It is important also to note that, before taking up with Dr. Abbott's work, Prof. Putnam took ample pains to satisfy himself Fig. 2. — Section across the Delaware River at Trentox, >'.

( From Abbott's Primitive Industry.) of its character and correctness. In 1878 Prof. J. D. Whitney visited Trenton in company with Mr. Carr, assistant curator of the museum. In the Twelfth Annual Report Mr. Carr writes : " We were fortunate enough to find several of these implements in place. Prof. Whitney has no doubt as to the antiquity of the drift, and we are both in full accord with Dr. Abbott as to the artificial character of many of these implements." In reporting further upon this instance at the meeting of the Boston Society of Natural History, on January 19, 1881, Mr. Carr states that the circumstances were such that " it [i. e., one of the particular im- plements] must have been deposited at the time the containing bed was laid down." In 1879, and again in 1880, Prof. Putnam spent some time at Trenton, and succeeded in finding with his own hands '"' five unquestionable palaeolithic implements from the gravel, at various depths and at different points." One of these was four feet below the surface soil and one foot in from the per- pendicular face which had just been exposed, and where it was 32 THE POPULAR SCIENCE MONTHLY. clear that the gravel had not been disturbed. A second one was eight feet below the surface. (Proc. Boston Soc. of Nat. Hist, for January 19, 1881.) As confirming the entire trustworthiness of Dr. Abbott's ob- servations, it is to be noted that, with a single exception, all the implements reported below the loam which constitutes the sur- face soil are of argillite, while those upon the surface, which are innumerable, are chiefly of a different type, made from flint and jasper, or of other material of related character. Another fact, which has always had great weight in my own mind, is one men- tioned by the late Prof. Carvill Lewis, in his chapter upon the subject at the end of Dr. Abbott's volume on Primitive Industry. I have the more reason to feel the , force of his conclusions, be- cause the proof-sheets passed through Lewis's hands at the time we were together conducting the survey in Pennsylvania, soon after we had visited the deposits in question. The fact was this : Prof. Lewis had been at work for a considerable time in classify- ing and mapping the gravels in the Delaware Valley, being all the while in ignorance of Dr. Abbott's work until his own results were definitely formulated. But, after he had accurately deter- mined the boundary between the glacial gravels and the far older gravels which surround them and spread over a considerable por- tion of the territory beyond, he found that the localities where Mr. Carr, Prof. Putnam, and Dr. Abbott had reported finding their implements in undisturbed gravel, all fell within the limits of the glacial gravels, and had in no case been put outside of those limits. Now, Dr. Abbott's house is situated upon the older gravel ; but at the time of most of his discoveries he had not learned to distinguish the one gravel from the other. If these implements are all from the surface and had been commingled with lower strata by excavations, landslides, or windfalls, there is no reason why they should not have been found in the older gravels as well as in those of glacial age. There is here a coin- cidence which is strongly confirmatory of the correctness of our conclusion that there is no mistake in believing that the imple- ments were originally deposited with the gravel where they were found. Such was the progress of discovery at the time when I began my special investigations upon the glacial boundary in Ohio, and of the glacial terraces there corresponding in age with that at Trenton. To the similarity of conditions along these streams I promptly called attention in 1883, pointing out various places in Ohio where it would be profitable for local observers to be upon the lookout for such evidences of glacial man as had been discov- ered by Dr. Abbott. The first response to this came from Dr. C. L. Metz, of Madisonville, on the Little Miami River, in southern EVIDENCES OF GLACIAL MAN IN OHIO. 33 Ohio. Dr. Metz is a physician of large practice, of high char- acter, and of long experience as an assistant of Prof, Putnam in exploring the mounds of Ohio. He knows the difference between disturbed and undisturbed gravel as i3erfectly as any one does. His residence is upon the glacial terrace which borders the Little Miami Valley. In 1885, while digging a cistern in this terrace, a perfectly formed implement of black chert was found by him in undisturbed gravel eight feet below the surface. This was ex- hibited by Prof. Putnam at a meeting of the Boston Society of Natural History, on the 4th of November, 1885, and is No. 40,970 in the Peabody Museum. Two other implements were discovered at a later time by Dr. Metz in the talus of the glacial terrace of the Little Miami, at Loveland, where also numerous bones of the Fig. 3. — Chipped Pebble of Black Chert, found by Dr. C. L. Metz, October, 1885, at Madisonville, Ohio, in gravel eight feet from surface under clay : «, face view ; ft, side view. Natural size. mammoth were found. But, as these were not in place when dis- covered, they can not be adduced as positive evidence. The discovery at Newcomerstown, of which Messrs. Holmes, Brinton, and McGee speak so lightly because they do not know the facts, is really one of the best attested of all the single cases. The discovery was made in 1889 by Mr. W. C. Mills. The imple- ment has been presented to the Western Reserve Historical Soci- ety of Cleveland, and can there be seen at any time in company with various implements from France. A photogravure from it appears in the smaller figure in the following cut. The discovery of the implement was made in October, but it was not brought to public notice until the next spring, when I chanced to meet Mr. Mills and learned about it. He then for- 34- THE POPULAR SCIENCE MONTHLY. warded it to me, when its exact resemblance in form and finish- ing to an implement which I have in my own collection, that was obtained by Dr. Evans, of London, at Amiens, France, greatly im- pressed me. I forwarded it immediately to Prof. H. W. Haynes, Fig. 4. -The Smaller is the Pal>eolith feom Newoomerstown,the Lakuer from Amienf, France (face view). Keduced one half in diameter. of Boston, whose expert judgment is second to that of no other person in America, or indeed of the world. Prof. Haynes ex- hibited it at the meeting of the Boston Society of Natural History on May 7, 1890, and his account was published in the Proceedings of that evening. In conclusion, after having enumerated its dis- tinctive characteristics, he said, " I desire to express most emphat- ically my belief in the genuineness and age of this Newcomers- town implement, as well as to call attention to the close resem- blance in all particulars which it bears to these unquestioned palEGolithic implements [which he exhibited beside it] of the Old World." This implement is not a " reject," but is a finished im- plement, with the secondary chippings all around the edge. The EVIDENCES OF GLACIAL MAN IN OHIO. 35 cuts, reproduced from photographs, perfect as they are, by no means do it justice. I promptly gave an account of this discovery in The Nation, in its issue for April 24, 1890, and repeated it in substance with some additional particulars on page 620 of the third edition of my volume on The Ice Age in Xorth America. This account was also reprinted in The Popular Science Monthly, Volume XXXIX, pages 314: to 319. The account in my later volume, on Man and the Glacial Period, is still more condensed. The more detailed evidence is published in Tract No. 75 of the Western Reserve His- torical Society, Cleveland, Ohio, containing the report of the meet- FiG. 5. — Edge View of the Pkeceiiing. I ing when Mr. Mills was present and gave his own testimony. This was held December 12, 1890. The facts are these : There is a glacial gravel terrace in New- comerstown at the mouth of Buckhorn Creek, where it enters the larger valley of the Tuscarawas River. There can be no question about the glacial age of this terrace. It is continuous up the 36 THE POPULAR SCIENCE MONTHLY river to the terminal moraine. Its surface is about thirty-five feet above the fiood-pkiiu of the Tuscarawas ; it consists of strati- fied material, containing many granitic pebbles and much gra- nitic gravel. The deposit at Newcomerstown extends over many acres, having been protected from erosion in the recess at the Fig. 6. mouth of Buckhorn Creek. Through the middle of this deposit the railroad had cut its road-bed, and for years has been appro- priating the gravel for ballast. Mr. Mills is an educated business man, who had been a pupil in geology of Prof. Orton, of the State University, and had with him done considerable field-work in geology. Mr. Mills's charac- ter and reputation are entirely above suspicion. In addition to his business he took a laudable interest in the collection of Indian relics, and had in his office thousands of flint implements, col- lected by him and his associates in the vicinity, who had been organized into an archeeological society. His office was but a short distance from the gravel pit from which I have said the EVIDENCES OF GLACIAL MAN IN OHIO. 37 railroad liad been for so many years obtaining ballast. The per- pendicular face of this bank of gravel as it was exposed from time to time by the excavations of the railroad men was frequently examined by Mr. Mills, not with special reference to finding im- plements, for that thought had not entered his mind, but for the sake of obtaining specimens of coral, which occasionally occurred in the gravel. While engaged in one of these rounds, on the 27th of October, 18S0, he found this specimen projecting from a fresh exposure of the perpendicular bank, fifteen feet below the sur- face, and, according to his custom, recorded the facts at the time in his note-book. There was no lack of discrimination in his ob- servations, or of distinctness in his memory.

C. Mills found a Paleo- lithic Implement. the base of the deposit, shows the spot in the bank from which the implement was taken. In looking for objects of his ciuest, Mr. Mills thrust in his cane into the coarser gravel which is seen to overlie the finer deposits. This resulted in detaching a large mass about six feet long and two feet wide, which fell down at his 38 THE POPULAR SCIENCE MONTHLY. feet. It was in the face of the bank behind this mass that Mr. Mills's eye, so long trained for the detection of artificially chipped flints, discovered the implement under consideration, which he removed with his own hands, and placed in his collection, with little thought at the time of the significance attach- ing to the position in which it was found. The accompanying map of the vicinity and drawing of the bank were made by Mr, Mills at the time of our visit, and furnish, with the photograph, all the additional informa- tion necessary. There is no possibility of mistake concerning the undisturbed character of the gravel from which Mr. Mills took the implement, and observed by him.

We had all the op- portunity to question and cross-question that could be desired. In conclusion, it is proper to say that the sweeping character and the suddenness of these attacks of Mr. Holmes and his asso- ciates upon the evidence of glacial man in America have been somewhat bewildering. It has come like thunder from a clear sky. One has but to go back to Mr. McGee's article in The Popu- lar Science Monthly for November, 1888, to find an unquestioning and enthusiastic indorsement of nearly all the facts concerning glacial man which I have incorporated in my recent volume upon Man and the Glacial Period, together with a number which I have omitted, except the discovery at Newcomerstown, which had not then been made. Had I been aware of the preparations which these investigators were making to discredit all past observers on the matter, I should have introduced more detailed evidence in my summar}^ in the volume referred to. Still, it is probably as well that the statements were left as they are, for they are all capable of ample proof ; and it is perhaps better for the public to be re- ferred for details to such fuller reports as are made in this article and in the other publications here indicated. I submit that this evidence is neither " chaotic " nor " unsatis- factory," but is as specific and definite and as worthy to be be- lieved as almost anything any expert in this country, or any other country, can be expected to produce. GROWTH OF OUR KNOWLEDGE OF THE DEEP SEA. By G. W. LITTLEHALES, chief of the division of chart consterction, united states iiy drogfaphic office. BEFORE the time of the project for the Atlantic telegraph cable in 1854, there seemed to be no practical value attached to a knowledge of the depths of the sea, and, beyond a few doubt- ful results obtained for purely scientific purposes, nothing was clearly known of bathymetry, or of the geology of the sea bottom. The advent of submarine cables gave rise to the necessity for an accurate knowledge of the bed of the ocean where they were laid, and lent a stimulus to all forms of deep-sea investigation. But although our extensive and accurate knowledge of the deep sea is of so late an origin, the beginnings of deep-sea research date far back into antiquity. The ancients can not be said to have had any definite conceptions of the deep sea. Experienced mariners, like the Phoenicians and Carthaginians, must necessarily have possessed some knowledge of the depths of the waters with which they were familiar, but this knowledge, whatever its extent, has 40 THE POPULAR SCIENCE MONTHLY. now passed away. To the writings of Aristotle, who lived during the fourth century B. c, are credited the first bathymetric data. He states that the Black Sea has whirlpools so deep that the lead has never reached the bottom ; that the Black Sea is deeper than the Sea of Azov, that the ^gean is deeper than the Black Sea, and that the Tyrrhenian and Sardinian Seas are deeper than all the others. The first record of a deep-sea sounding should be credited to Posidonius, who stated, about a century B. c, that the sea about Sardinia had been sounded to a depth of one thousand fathoms. No account is given of the manner in which the sound- ing was taken, and we have no information as to the methods employed by the ancients in these bathymetric measurements. The opinions of the learned with respect to the greatest depth of the sea, in the first and second centuries a. d., may be gleaned from the writings of Plutarch and Cleomedes, the first of whom says, " The geometers think that no mountain exceeds ten stadia [about one geographic mile] in height, and no sea ten stadia in depth." And the second : " Those who doubt the sphericity of the earth on account of the hollows of the sea and the elevation of the mountains, are mistaken. There does not, in fact, exist a mountain higher than fifteen stadia, and that is also the depth of the ocean," There was no important addition to our knowledge of the deep sea during the middle ages, and no definite attempt to provide effective means for deep-sea sounding appears to have been made until Nicolaus Causanus, who lived in the first half of the fifteenth century, invented an apparatus consisting of a hollow sphere, to which a weight was attached by means of a hook, intended to carry the sphere down through the water with a certain velocity. On touching the ground the weight became detached and the sphere ascended alone. The depth was calculated from the time the sphere was under water. This apparatus was afterward mod- ified by Pliicher and Alberti, and, in the seventeenth century, by Hooke, who substituted a piece of light wood well varnished over for the hollow sphere. Hooke's instrument was no doubt fairly accurate in shallow water, but useless in great depths, where the enormous pressure waterlogged the wood and, by materially in- creasing its density, greatly diminished the speed with which it rose from the bottom. When used in currents the float was car- ried away and the record lost. During the period when the voyages of Columbus, Vasco da Gama, and Magellan added a hemisphere to the chart of the world and forever established the fundamental principles of all scientific geography, navigators had sounding lines of one hundred and two hundred fathoms in length, and, although they eagerly studied the oceanic phenomena revealed at the surface, the deep sea did not OUR KNOWLEDGE OF THE DEEP SEA. 41 engage their attention. Kirclier, in his Mundus Subterraneus, gives the ideas as to the depths of the sea that were accepted in the first half of the seventeenth century, stating that " in the same manner as the highest mountains are grouped in the center of the land, so also should the greatest depths be found in the middle of the largest oceans ; near the coasts with but slight ele- vations the depth will gradually diminish toward the shore. I say coasts with but slight elevations, for, if the shores are sur- rounded by high rocks, then greater depths are found. This is proved by experience on the shores of Norway, Iceland, and the islands of Flanders." Several soundings were taken in deep water during the eight- eenth century, but they were not of much value. The first at all reliable were made by Sir John Ross during his well-known arc- tic expedition in 1818. He brought up six pounds of mud from 1,050 fathoms in Baffin Bay, and obtained correct soundings in 1,000 fathoms in Possession Bay, finding worms and other animals in the mud procured. Sir James Clark Ross, during his antarctic expedition from 1839 to 1843, obtained satisfactory soundings of 2,425 and 2,677 fathoms in the South Atlantic, with a hempen cord. He also dredged successfully in depths of 400 fathoms. Meanwhile, about the middle of the eighteenth century, the first definite ideas about the formation of the bottom soil began to be advanced, although there had been speculations on the formation of alluvial layers since the time of Herodotus. In 1725 Marsilli made a few observations on the bathymetric knowledge then pos- sessed concerning the nature of the bottom of the sea. He admit- ted that the basin of the sea was excavated " at the time of the creation out of the same stone which we see in the strata of the earth, with the same interstices of clay to bind them together," and pointed out that we should not judge of the nature of the bot- tom of the basins by the materials which seamen bring up in their soundings. The dredgings almost always indicate a muddy bot- tom, and very rarely a rocky one, because the latter is covered with slime, sand, and sandy, earthy, and calcareous concretions, and organic matter. These substances, he said, conceal the real bottom of the sea, and have been brought there by the action of the water. Lastly, by way of explanation, he compared the bed of the sea to the inside of an old wine cask, which seems to be made of dregs of tartar although it is really of wood. Donati's studies on the bottom of the Adriatic Sea led him to announce, about the middle of the eighteenth century, that it is hardly different from the surface of the land, and is but a prolon- gation of the superposed strata in the neighboring continent, the strata themselves being in the same order. The bottom of this sea is, according to him, covered with a layer formed by crusta- VOL. XLIII. 4 42 THE POPULAR SCIENCE MONTHLY. ceans, testaceans, and polyps, mixed with sand, and to a great ex- tent petrified. This crust may be seven or eight feet deep, and he attributed to this deposit, bound together with the remains of or- ganisms and sedimentary mineral matter, the rising of the bot- tom of the sea, and the encroachment of the water on the coasts. In 1836 Ehrenberg produced the first of a long series of publi- cations relating to microscopic organisms which distinguished him as a naturalist of rare sagacity. He devoted the whole of his life to the study of microscopic organisms, to the examination of ma- terials brought up from deep-sea soundings, and to all questions appertaining to the sea. Having discovered that the siliceous strata known as tripoli, found in various parts of the globe, are but accumulations of the skeletons of diatoms, sponges, and radio- laria, and having found living diatoms and radiolaria on the sur- face of the Baltic of the same species as those found in the Ter- tiary deposits of Sicily, and having shown that in the diatom layers of Bilin in Bohemia the siliceous deposit had, under the influ- ence of infiltrated water, been transformed into compact opaline masses, he concluded that rocks like those which play so impor- tant a part in the terrestrial crust are still being formed on the bottom of the sea. The investigation of the distribution of marine animals accord- ing to the depths of the sea may be said to have commenced in 1840 with Forbes's studies in the Mediterranean. He maintained that the dredgings showed the existence of distinct regions at suc- cessive depths, having each a special association of species ; and remarks that the species found at the greatest depths are also found on the coast of England — concluding, therefore, that such species have a wider geographical distribution. He divided the whole range of depth occupied by marine animals into eight zones, in which animal life gradually diminished with increase of depth, until a zero was reached at about three hundred fathoms. He also supposed that plants, like animals, disappeared at a certain depth, the zero of vegetable life being at a less depth than that of animal life. It has already been mentioned that probably the first reliable deep-sea soundings ever made were by Sir John Ross in 1818. To him is due the invention of the so-called deep-sea clam, by means of which specimens of the bottom were for the first time brought up from great depths in any quantity. This instrument was in the form of a pair of spoon-forceps, kept apart while descending, but closed by a falling weight on striking the bottom. Two separate casts were usually made, one to ascertain the depth and the other to bring up a specimen of the bottom soil. For the development of accurate knowledge of the depths of the sea the world will ever be indebted to the genius of Midship- OUR KNOWLEDGE OF THE DEEP SEA. 43 man Brooke, of the United States Navy, who made the first great improvement in deep-sea sounding in 1854 by inventing a machine in which, applying Causanus's idea of disengaging a weight at- tached to the sounding line, the sinker was detached on striking the bottom and left behind when the tube was drawn up. The arrangement of the parts is shown in the accompanying figure. When the tube B strikes the bottom, the lines A A slack and allow the arms C C to be pulled down by the weight D. When these arms have reached the positions indicated by the dotted lines, the slings supporting the weight have slipped off, and the tube can be hauled up, bringing within it a specimen of the bottom. This implement has been improved from time to time by various officers of our own and foreign navies by changing the manner of slinging and detaching the sinker, and by adding valves to the upper and lower ends of the tube to prevent the specimen from being washed out during the rapid ascent which has been rendered possible by the use of wire sounding line and steam hoisting engines ; but in all the essential features it is the same as the most successful modern sounding apparatus. The impulse given to deep-sea sounding by Brooke was seconded by the successful adaptation of pianoforte wire to use as a sounding line, in 1872, by Sir William Thomson ; and within recent years soundings have been taken far and wide in all the seas by national vessels during their cruises, by vessels engaged in laying submarine cables, and by various specially organized expeditions, among which that known as the Challenger Expedition, sent out by the Government of Great Britain during the period from 1873 to 1876, stands pre-eminent. As a result of this work many of the ques- tions which perplexed the naturalists of the middle of the present century have now been cleared away. Many of the specimens of the bottom that were brought up in the early days of deep-sea sounding were studied through the microscopes of Ehrenberg, of Berlin, and Bailey, of West Point. Maury, who believed that there are no currents and no life at the bottom of the sea, wrote : " They all tell the same story. They teach us that the quiet of the grave reigns everywhere in the profound depths of the ocean ; that the repose there is beyond the reach of wind ; it is so perfect that none of the powers of earth, save only the earthquake and volcano can disturb it. The 44 THE POPULAR SCIEXCE MONTHLY. specimens of deep-sea soundings are as pnre and as free from the sand of tlie sea as the snowflake that falls when it is calm upon the lea is from the dust of the earth. Indeed, these soundings suggest the idea that the sea, like the snow cloud with its flakes in a calm, is always letting fall upon its bed showers of these micro- scopic shells; and we may readily imagine that the 'sunless wrecks ' which strew its bottom are, in the process of ages, hid under this fleecy covering, presenting the rounded appearance which is seen over the body of a traveler who has perished in the snowstorm. The ocean, especially within and near the tropics, swarms with life. ' The remains of its myriads of moving things are conveyed by currents, and scattered and lodged in the course of time all over its bottom. The process, continued for ages, has covered the depths of the ocean as with a mantle, consisting of organisms as delicate as the macled frost and as light as the un- drifted snowflake. of the mountain." Maury was right in respect to the covering of the bed of the deep sea, for, as a result of all our researches, it is found that in waters removed from the lajid and more than fourteen hundred fathoms in depth there is an almost unbroken layer of pteropod, globigerina, diatom, and radiolarian oozes, and red clay which occupies nearly 115,000,000 of the 143,000,000 square miles of the water surface of the globe. But he was wrong in asserting that low temperature, pressure, and the absence of light preclude the possibility of life in very deep water. Ehrenberg held the opposite opinion with regard to the condi- tions of life at the bottom of the sea, as may be seen from the fol- lowing extract from a letter which he wrote to Maury in 1857 : " The other argument for life in the deep which I have established is the surprising quantity of new forms which are wanting in other parts of the sea. If the bottom were nothing but the sedi- ment of the troubled sea, like the fall of snow in the air, and if the biolithic curves of the bottom were nothing else than the prod- uct of the currents of the sea which heap up the flakes, similarly to the glaciers, there would necessarily be much less of unknown and peculiar forms in the depths. The surface and the borders of the sea are much more productive and much more extended than the depths ; hence the forms peculiar to the depths should not be perceived. The great quantity of peculiar forms and of soft bodies existing in the innumerable carapaces, accompanied by the obser- vation of the number of unknowns, increasing ivith the depth — these are the arguments which seem to me to hold firmly to the opinion of stationary life at the bottom of the deep sea." It would appear to have been definitely established by the re- searches of the last fifty years that life in some of its many forms is universally distributed throughout the ocean. Not only in the OUR KNOWLEDGE OF THE DEEP SEA. 45 shallower waters near coasts, but even in the greater depths of all oceans, animal life is exceedingly abundant. A trawling in a depth of over a mile yielded two hundred specimens of animals be- longing to seventy-nine species and fifty-five genera. A trawling in a depth of about three miles yielded over fifty specimens be- longing to twenty-seven species and twenty-five genera. Even in depths of four miles fishes and animals belonging to all the chief invertebrate groups have been procured, and in a sample of ooze from nearly five miles and a quarter there was evidence to the naturalists of the Challenger that living creatures could exist at that depth. Recent oceanographic researches have also established beyond doubt that while in great depths the water is not subjected to the influence of superficial movements like waves, tides, and swift currents, there is an extremely slow movement, in striking con- trast with the agitation of the surface water. Although the movement at the bottom is so slow that the ordinary means of measuring currents can not be applied accurately to them, the thermometer furnishes an indirect means of ascertaining their ex- istence. Water is a very bad conductor of heat, and consequently a body of water at a given temperature passing into a region where the temperature conditions are different retains for a long time, and without much change, its original temperature. To illustrate : The bottom temperature near Fernando do Noronha, almost under the equator, is 0"2° C, or close upon the freezing point ; it is obvious that this temperature was not acquired at the equator, where the mean annual temperature of the surface layer of the water is 21° C, and the mean normal temperature of the crust of the earth not lower than 8° C. The water must therefore have come from a place where the conditions were such as to give it a freezing temperature ; and not only must it have come from such a place, but the supply must be continually renewed, how- ever slowly, for otherwise its temperature would gradually rise by conduction and mixture. Across the whole of the North Atlantic the bottom temperature is considerably higher, so that the cold water can not be coming from that direction ; on the other hand, we can trace a band of water at a like temperature at nearly the same depth continuously to the Antarctic Sea, where the condi- tions are normally such as to impart to it this low temperature. There seems, therefore, to be no doubt that there is a current from the antarctic to the equator along the bottom of the South Atlantic. From the millions of reliable deep-sea soundings that have been made during the last forty years the more general features of the bathymetric chart of the world have been firmly estab- lished; and the ancient idea, derived chiefly from a supposed 46 THE POPULAR SCIENCE MONTHLY. physical relation, that the depths of the sea are about equal to the heights of the mountains, has given place to exact notions as to the depths as well as the heights. The greatest known depths that have been reliably sounded in the different oceans are given in the following list : Latitude. Longitude. Depth in fathoms.

WESLEY MILLS, M. A., M. D., MC GILL UNIVERSITY, MONTREAL. THE main object of every society for the prevention of cruelty to animals I take to be the establishment of right feelings toward our speechless fellow-creatures. But feeling, to be correct, strong, and abiding, must be based on sound conceptions of the nature of that toward which it is exercised. So long as any indi- vidual believes that another wishes to injure him, so long will he find it most difficult to entertain kindly feelings toward the man that he deems his enemy ; but let it appear that he has entirely misunderstood the motive and actions of the individual in ques- tion — that instead of an enemy he proves to be a friend — and the whole current of .feeling is changed. Thus would it be, in my opinion, with thousands of people if they could be made to see animals in their true light. Glancing at historical and national views of animal life, we find at all periods widely different conceptions, and consequently * An Address before the American Humane Association, Philadelphia, October 27, 1892. HUMANE IDEAS AND FEELINGS. 47 feelings, in regard to some of our domestic animals. A certain animal regarded as a fit subject for contempt by some peoples lias been an object of worship, or something akin to it, by others ; hence it is not surprising that the lot of such animals has been very different in some parts of the world as compared with others. To illustrate this we need go no further than the universally dis- tributed dog and cat. In the East the dog is rarely other than a homeless, despised outcast. In Europe generally he is a mem- ber of the family. But it is to Great Britain especially that we look to find all our domestic animals in the highest perfection, and cherished with feelings of peculiar regard. In Britain it is contrary to law to hitch a dog, however large and strong, to a cart to draw even a small child, while in Germany dogs may be seen used as beasts of burden in all the large cities. In no part of the world are the good qualities of dogs so appreciated and valued as in Great Britain ; hence it is not at all inexplicable that cruelty to the dog and other animals is there comparatively rare. It may safely be said that never before in civilized countries were animals — and especially our domestic animals — treated so well, because never before were they so thoroughly understood. To what is this to be attributed ? Not alone to the spread of kind- lier feelings and better principles generally, but largely to the advance of science. There was a time, well within the recollec- tion of persons not yet old, when man, we were told by those to whom we looked for light and guidance, stood utterly apart from all else in the universe as the one being in whom the Creator specially, and we might say solely, delighted, and for whose benefit every other object, animate and inanimate, existed. How natu- ral, then, for man to believe that animals, as such, had few if any rights ! The one test to which many persons naturally enough brought every animal was just this : Is the creature of any use whatever to man ? If not, then it was held that it simply cumbered the ground. People, it is true, admitted that man was an animal ; but they did not realize what this expression meant, or did not accept it in its full significance. To them man was an " animal," but not like the others. He was too exalted to have any more than the common principle of life. Men could not realize then as now that mind and body are so closely related that for every mental process there must be a corresponding physical correlative. But this once being admitted it became possible to understand that animals be- low man may have minds whose processes are akin to ours. The question then became, not have animals minds, but what sort of minds. Wherein does animal intelligence in the widest sense dif- fer from human intelligence ? As soon as man himself became better understood it was plain that his feelings were, on certain 48 THE POPULAR SCIENCE MONTHLY. planes, parallel witli groups of animals much lower in the scale generally. To them pleasures and pains were just as real as they were similar to those of human beings. I suggest that these most important advances are owing chiefly to the progress and the diffusion of scientific knowledge and the scientific spirit. The doctrine of organic evolution published by Darwin over thirty years ago at once offered to man a broader kinship than he had previously been able to comprehend. In my opinion the importance of this conception will, for a right under- standing of the relations of man and other animals, outweigh all others, because it will bring us to see that, with a common origin, there must always remain numerous similarities of nature. But, without taking advantage of the doctrine of evolution, it has become apparent that the claim for man of a nature entirely distinct and different from that of other forms of life is baseless. Gradually, from many different quarters, this conception of simi- larity of nature is spreading among the masses ; and the friend of animals can not do better than encourage people to dwell upon the resemblances rather than the differences between the highest and the lower grades of animal life. It will be readily perceived, then, that my conviction is that we shall best advance the cause we have at heart — the humane treatment of our animals — by spread- ing sound views of their nature, and in that keeping prominent the resemblances to man rather than the differences from him, many of them questionable, at all events as to kind. Inasmuch as science has done more than all other agencies in dissipating man's prejudices and freeing the mind from erroneous and enslaving views, it will be wise for all societies with a hu- mane object to think well before in any way interfering with sci- entific investigations of any kind. Without research the true nature of those diseases which afflict man and the lower animals can not be known. With many persons dogs and hydrophobia are closely associ- ated mentally, and I recently read an article in which the author spoke of the dog as the " breeder of hydrophobia." The societies will do good by publishing actual statistics and other details bear- ing on the nature of this dreaded disease. I have also read argu- ments for the complete extirpation of dogs based on the fact that some sheep were worried. The plain preventive for rabies is the proper care and management of dogs; and for sheep-worrying, the confinement of dogs at night, which would be, indeed, a proper proceeding if no sheep existed. A roaming dog is no more desirable than a human tramp ; but no one has advocated the destruction of the human race to get rid of tramps. In attempt- ing to spread sound views in regard to diseases that are common to man and our domestic animals, such as rabies, indirectly much HUMANE IDEAS AND FEELINGS. 49 information will be given to the public about the care of dogs, with a view to avoiding conditions that simulate this terrible malady. The " mad dog " of the streets is, we know, rarely rabid, and usually only needs a little judicious and kindly assistance to restore him to health. It is just about as reasonable to pounce on and kill a human being that falls in an epileptic fit, as the majority of the dogs that are attacked and killed by an excited crowd. Above all, the public needs enlightenment regarding the true nature of animals. When that is complete and thorough, right feelings toward them will spring up in the larger proportion of people. I would especially direct attention to the education of children in and out of school on this subject. It should be held before a child as a more cowardly thing to abuse a defenseless animal than one of its own species. But this will not weigh much with the child if all it hears tends to belittle the creatures by which it is surrounded, and to exalt man beyond all measure. I should begin with very young children by pointing to similarities of structure and function between themselves and the family cat or dog. They have eyes, ears, tongues, etc. ; they see, hear, taste, feel pain, and experience pleasure just as children do ; therefore, let us recognize their rights, avoid giving them pain, and increase their pleasures. I strongly advocate each family having some one animal, at least, to be brought up with the household to some extent, whether it be bird, cat, or dog. But, on the other hand, it seems to me to be a great mistake to introduce any animal as a mere toy or plaything for very young children. Such a proceed- ing rather tends to encourage cruelty. It is of great importance for the education of the public mind that fine specimens of animals be exhibited. All shows for our domestic animals are worthy of encouragement as educators. Many a person that regards the ordinary mongrel dogs of the street with indifference, if not aversion, has his views and feelings changed when he attends a dog show, with its numerous speci- mens of fine, pure-bred animals ; and the same may be said of horse, cattle, and poultry shows. The aesthetic has a very great influence in our age. We devote a large share of our energies to securing the gratification of our sense of the beautiful. It will be judicious, therefore, to present the beautiful in animals to the public. For this reason, again, exhibitions of superior specimens of domestic animals, zoological gardens, museums, and kindred institutions prepare the public mind to appreciate animals more ; and, as I am endeavoring to show, to understand and to admire are usually necessary steps to the generation of humane feelings toward the creatures with which we come in contact. Once establish the proper feelings, and fitting conduct is likely to follow ; but before these feelings arise we must have right con- yoL.

While many persons are ready to admit that, so far as phys- ical organization is coiicerned, man and other animals are on the one plane, they either do not believe in any likeness beyond this, or more probably they have never examined the subject. It is not unlikely that the great majority of persons have not devoted a half hour of their lives, taken altogether, to any thought upon such a subject. It has been taken for granted that man is on
