THE NOACHIAN DELUGE.
PART II.
A centuryhas not yet gone by since all the organic remains on which the science of Palæontology is now founded were regarded as the wrecks of a universal deluge, and held good in evidence that the waters had prevailed in every known country, and risen over the highest hills. Intelligent observers were not wanting at even an earlier time who maintained that a temporary flood could not have occasioned phenomena so extraordinary. Such was the view taken by several Italian naturalists of the seventeenth century, and in Britain by the distinguished mathematician Hooke, the contemporary, and in some matters rival, of Newton. But the conclusions of these observers, now so generally adopted, were regarded both in Popish and Protestant countries as but little friendly to Revelation; and so strong was the opposite opinion, and so generally were petrifactions regarded as so many proofs of a universal deluge, that Voltaire felt himself constrained, first in his Dissertation drawn up for the Academy at Bologna, and next in his article on shells in the Philosophical Dictionary, to take up the question as charged with one of the evidences of that Revelation which it was the great design of his life to subvert. And with an unfairness too characteristic of his sparkling but unsolid writings, we find him arguing, that all fossil shells were either those of freshwater lakes and rivers evaporated during dry seasons, or of land snails developed in unusual abundance during wet ones; or that they were shells which had been dropped from the hats of pilgrims on their way from the Holy Land to their homes; or that they were shells that had gone astray from cabinets and museums; or, finally, that they were not shells at all, but mere shell-like forms, produced by some occult process of nature in the bowels of the earth. In fine, in order to destroy the credibility of the Noachian deluge, the brilliant Frenchman exhausted every expedient in his attempts to neutralize that Palæontologic evidence on which geologists now found some of their most legitimate conclusions. But he only succeeded, instead, in producing compositions of which every sentence contains either an absurdity or an untruth, and in raising a reaction against the special school of infidelity which he had founded, that at length bore it down. He wrote in the middle of the Paris basin, with its multitude of fossil shells and bones; and, when penning his article for the Encyclopædia, he had, he tells us, a boxful of the shell-charged soil of the Faluns of Touraine actually before him; but the deluge had to be put down, whatever the nature or bearing of the facts; and so he could find in either no evidence of a time when the sea had covered the land. He found, instead, only "some mussels, because there were ponds in the neighborhood." As for the "spiral petrifactions termedcornu ammonis," of which the Jurassic Alps are full, they were not nautili, he said; they could be nothing else than reptiles; seeing that reptiles take almost always the form of a spiral when not in motion; and it was surely more likely, that when petrified they should still retain the spiral disposition, than that "the Indian Ocean should have long ago overflowed the mountains of Europe." Were there not, however, real shells of the Syrian type inFrance and Italy? Perhaps so. But ought "we not to recollect," he asked, "the numberless bands of pilgrims who carried their money to the Holy Land, and brought back shells? or was it preferable to think that the sea of Joppa and Sidon had covered Burgundy and Milanais?" As for the seeming shells of the less superficial deposits, "Are we sure," he inquired, "that the soil of the earth cannot produce fossils?" Agate in some specimens contains its apparent sprigs of moss, which, we know, never existed as the vegetable they resemble; and why should not the earth have, in like manner, produced its apparent shells? Or are not many of these shells mere lake or river petrifactions?—one never sees among them "true marine substances"!! "If therewereany, why have we never seen bones of sea dogs, sharks, and whales?"!!! And thus he ran on, in the belief apparently that he had to deal with but an ignorant priesthood, too little acquainted with the facts to make out a case against him in behalf of the Mosaic narrative, and whom at least, should argument fail him, he could vanquish with a joke.
There was, however, a young German, who had not at the time quite made up his mind either for the French school or against it, who was no uninterested reader of Voltaire's disquisitions on fossil shells. And this young man was destined to be in the coming age what the Frenchman had been in the closing one,—the leading mind of Europe. He, too, had been looking at fossils; and having no case to make out either for or against Moses, or any one else, he had received in a fair and candid spirit the evidence with which they were charged. And the gross dishonesty of Voltaire in the matter formed so decided a turning point with him, that from that time forward he employed his great influence in bearing down the French school of infidelity, as a school detestably falseand hollow;—a warning, surely, to all, whether they stand up for Revelation or against it, of the danger of being, like the witty Frenchman, "wicked overmuch." "To us youths," says Goethe, in his Autobiography, "with our German love of truth and nature, the factious dishonesty of Voltaire, and the perversion of so many worthy subjects, became more and more annoying, and we daily strengthened ourselves in our aversion from him. He could never have done with degrading religion and the sacred books for the sake of injuring priestcraft, as he called it; and thus produced in me many an unpleasing sensation. But when I now learned, that to weaken the tradition of a Deluge, he had denied all petrified shells, and only admitted them aslusus naturæ, he entirely lost my confidence; for my own eyes had on the Baschberg plainly enough shown me that I stood on the bottom of an old dried-up sea, among theexuviæof its ancient inhabitants. These mountains had certainly been once covered with waves,—whether before or during the Deluge did not concern me: it was enough that the valley of the Rhine had been a monstrous lake,—a bay extending beyond the reach of eyesight: out of this I wasnotto be talked. I thought much more of advancing in the knowledge of lands and mountains, let what would be the result." I know not in the whole history of opinion a more instructive passage than this. Little could Voltaire have known what he was in reality doing, or how egregiously he was overreaching himself, when, in laboring to bear down the evidence borne by fossils to the ancient upheavals and cataclysms, he suffered himself to make use of assertions and arguments so palpably unfair. And those who employ, in their zeal against the geologists, what is still exceedingly common,—the Voltairean style of argument,—especially if they employ it in whatthey deem the behalf of religion, might do well to inquire whether they are not in some little danger of producing the Voltairean result.
No man acquainted with the general outlines of Palæontology, or the true succession of the sedimentary formations, has been able to believe, during the last half century, that any proof of a general deluge can be derived from theoldergeologic systems,—Palæozoic, Secondary, or Tertiary. It has been held, however, by accomplished geologists, within even the last thirty years, that such proof might be successfully sought for in what are known as the superficial deposits. Such was the belief of Cuvier,—a man who, even in geologic science, which was certainly not his peculiar province, exerted a mighty influence over the thinking of other men. "I agree with MM. Deluc and Dolomieu in thinking," we find him saying, in his widely famed "Theory of the Earth," "that if anything in geology be established, it is, that the surface of our globe has undergone a great and sudden revolution, the date of which cannot be referred to a much earlier period than five or six thousand years ago." But from the same celebrated work we learn that Cuvier held that this sudden catastrophe,—occasioned, as he supposed, by an elevation of the sea bottom and a submergence of the previously existing land,—hadnotbeen universal; seeing he could entertain the belief that the three great races of the human family,—Ethiopian, Mongolian, and Caucasian,—had all escaped from it in several directions. In referring to the marked peculiarities of the Mongolian race, so very distinct from the Caucasian, he merely intimates, that he was "tempted to believe their ancestors and ours had escaped the great catastrophe on different sides;" but in dwelling on the still more marked peculiarities of the Negroes, we find him explicitly stating, that, "all theircharacters clearly show that they had escaped from the overwhelming deluge at another point than the Caucasian and Altaic races; from which they had perhaps been separated," he adds, "for a long time previous to the occurrence of that event." For a season, geologists of high standing in our own country, such as Buckland and Conybeare, followed Cuvier so far as to hold, that the superficial deposits bore evidence everywhere of a great cataclysm, the last of the geologic catastrophes; and which might be identified, they believed, with the Noachian Deluge. Against this view one of the most distinguished of Scottish naturalists, Dr. John Fleming, raised a vigorous protest as early as the year 1826, and conclusively showed that no temporary flood could have produced the existing appearances. And so thoroughly were his facts and reasonings confirmed by subsequent discovery, that the geologists of name who had acquiesced, wholly or in part, in the Cuvierian view, read in succession their recantations: Dr. Buckland in especial, who had written most largely on the subject, and committed himself most thoroughly, did so a very few years after: nor does the hypothesis of Cuvier appear to have been since adopted by any writer of scientific reputation. Instead, therefore, of contending with arguments or inferences which there are now no parties in the field to maintain, I shall briefly refer to a few of the leading characteristics of those superficial deposits on which the abandoned conclusions were originally based, and show, in the passing, that they are not such as a temporary deluge could have produced.
The superficial deposits include what is known as the mammaliferous crag, the drift, the boulder and brick clays, the stratified sands and gravels, the travelled rocks, the ösars, and moraines of thehigherlatitudes. For it is a fact very significant in its bearings on the diluvial controversy,that it is in the higher latitudes in both hemispheres that these peculiar deposits are chiefly to be found. They have been traced in Patagonia in the one hemisphere, from the southern limits of the country to the forty-first degree of south latitude; and in Europe in the other, to the fortieth; and in America to even the thirty-eighth degree of north latitude. But in the great belt, nearly eighty degrees in breadth, which, encircling the globe from east to west, includes with the torrid the warmer portions of the temperate zones, they have scarce any existence at all, or exist at least in different forms and exceedingly reduced proportions. The superficial deposits, in their most characteristic conditions, are deposits of the colder portions of the globe, and in many parts indicate that there prevailed during their formation a much severer climate than now obtains in the regions in which they occur. The shells which they contain in Britain, for instance, though almost all of existing species, are many of them such as are not now to be found in the British seas, but in seas about ten degrees further to the north; and there is evidence that the line of perpetual snow must have descended at the time to a lower level than that attained by our second-class hills, and that almost every Highland valley had its glacier. They represent, too, vast periods of time;—earlier periods, during which the land gradually sank, till only its higher eminences were uncovered, and great floats of icebergs went careering over its submerged plains and lower hills; and later periods, during which the land as gradually arose, after apparently many pauses and oscillations, until at length, when it had reached a level scarce eighty feet higher than that which it at present maintains, the climate softened, and the glaciers which had formed in the later times among its hills ultimately disappeared. Beds of sea-shells of the boreal type, that belong to thoseice ages, may be still found occupying the places in which they had lived and died, many miles inland, and hundreds of feet over the sea level. Boring shells, such as the pholodadidæ, may be detected far out of sight of the ocean, still occupying the cells which they had scooped out for themselves in hard limestone or yielding shale; and serpula and nuliporate encrustations may be seen still adhering to rocks raised to giddy elevations over the sea. The group of mammals, however, which lived during this period, and to whose abundant tusks and skeletons one of its older deposits (the mammaliferous crag) owes its name, was marked by so peculiar a character, that evidence of a universal deluge has been often sought for in their remains. The group,—that which immediately preceded the animals of our own times, and included not a few of the indigenous species which still inhabit our country,—was chiefly remarkable for containing many genera, all of whose existing species are exotic. It had its great elephant, its two species of rhinoceros, its hippopotamus, its hyæna, its tiger, and its monkey; and much ingenious calculation has been employed by writers such as Granville Penn, in attempting to show how these remains might have been transported from the intertropical regions during the Flood, not only to Britain, but even to the northern wastes of Siberia,—a voyage of from four to five thousand miles. There are instances on record in which the bodies of the drowned have been drifted from ninety to a hundred and fifty miles from the spot where they had been first submerged; but they have always been found, in these cases, in a condition of sad mutilation and decay; whereas the carcass of the ancient elephant which was discovered, a little ere the commencement of the present century, locked up in ice in Siberia, three thousand six hundred miles from where elephants now live, was in such a state of excellent keeping,that the bears and dogs fed upon its flesh. It seems a significant circumstance too, that the remains of these fossil elephants, tigers, and hyænas, should be associated in even our own country with those of well known northern species,—with the remains of the reindeer, of the red deer, of the Lithuanian auroch, of the European beaver, of the European wolf, of the wild cat, the fox, and the otter. Writers, however, such as Mr. Penn, got over both difficulties. He showed, for instance, how a ship had once run across the Atlantic under bare poles, during an almost continued hurricane, at the rate of two hundred and eighty-eight miles in twenty-four hours,—nearly the rate at which the great American steamers cross the same ocean now; and why, he asked, might not the carcasses of elephants have drifted northwards at an equal rate on the tides of the deluge? And as for the mixed character of the group with which these remains are found associated,thatwas exactly what Mr. Penn would have expected in the circumstances. It was the result of a tumultuary flood, which had brought together in our northern region the floating carcasses of the animals of all climates, to sink in unwonted companionship, when putrefaction had done its work, into the same deposits. He had, however, unluckily overlooked the fact, that comparative anatomy is in reality a science; and further, that it is a science of which men such as Cuvier and Owen know a great deal more than the men who never studied it, however respectable. It is the recorded decision of these great anatomists,—a decision which has been many times tested and confirmed,—that the northern species of elephant, rhinoceros, tiger, and hyæna, were entirely different from the intertropical species; that they differed from them very considerably more than the ass differs from the horse, or the dog from the wolf; and that, while there is a preponderating amountof evidence to show that they were natives of the countries in which their remains are now found, there is not a shadow of evidence to show that they had ever lived, orcouldhave lived, in an intertropical country. Of the northern elephant, it is positively known, from the Siberian specimen, that it was covered, like many other sub-arctic animals, with long hair, and a thick crisp undergrowth of wool, about three inches in length,—certainly not an intertropical provision; and so entirely different was it in form from either of the existing species, African or Indian, that a child could be taught in a single lesson to distinguish it by the tusks alone. In fine, the assumption that challenges the remains of the old Pleistocene carnivora and pachydermata as those of intertropical species brought northwards by a universal deluge, is about as well based and sound as if it challenged the bones of foxes occasionally found in our woods for the remains of dogs of Aleppo or Askalon brought into Britain by the Crusaders, or as if it pronounced a dead ass to be one of the cavalry horses of the fatal charge of Balaklava, transported to England from the Crimea as a relic of the fight. The hypothesis confounds as a species the Rosinante of Quixote with the Dapple of Sancho Panza, and frames its argument on the mistake.
That this extinct group of animals inhabited for ages the countries in which their remains are now embedded, is rendered evident by their great numbers in some localities, and from their occurrence in various states of preservation, and in beds of various ages. The five hundred mammoths whose tusks and grinders were dragged up in thirteen years by the oyster dredgers of the Norfolk coast from a tract of submerged drift, could not all have been contemporary in a small corner of England, but must have represented several generations. And of course the twothousand grinders brought up from the exposed surface of the drift must have borne but a small proportion to the thousands still dispersed throughout the entire depth of the deposit. Any argument, however, founded on the mere numbers of these elephantine tusks and grinders, and which evaded the important question of species, might be eluded, however unfairly, by the assertors of a universal deluge. Floods certainly do at times accumulate, in great heaps, bodies of the same specific gravity; and why might not a universal flood have accumulated on this special tract of drift, the carcasses of many elephants? But it will be found greatly more difficult to elude the ingenious argument on the general question of Professor Owen. Next, perhaps, to the extinct elephant, one of the most numerous animals of this ancient group was the great Irish elk,Megaceros Hibernicus, a creature that, measured to the top of its enormous antlers, stood ten feet four inches in height, and exceeded in bulk and size the largest horses. Like all other species of the deer family, the creature annually shed and renewed its horns; "and a male deer may be reckoned," says Professor Owen, "to have left about eight pairs of antlers, besides its bones, to testify its former existence upon the earth. But as the female has usually no antlers, our expectations might be limited to the discovery of four times as many pairs of antlers as skeletons in the superficial deposits of the countries in which such deer have lived and died. The actual proportion of the fossil antlers of the great extinct species of British Pliocene deer (which antlers are proved by the form of their base to have been shed by the living animals) to the fossil bones of the same species, is somewhat greater than in the above calculation. Although, therefore, it may be contended that the swollen carcass of a drowned exotic deer might be borne along a diluvialwave to a considerable distance, and its bones ultimately deposited far from its native soil,it is not credible that all the solid shed antlers of such species of deer could be carried by the same cause to the same distance; or that any of them could be rolled for a short distance, with other heavy debris of a mighty torrent, without fracture and signs of friction. But the shed antlers of the large extinct species of deer found in this island and in Ireland havecommonly their parts or branches entire as when they fell; and the fractured specimens are generally found in caves, andshow marks of the teeth of the ossivorous hyænasby which they had been gnawed; thus at the same time revealing the mode in which they were introduced into those caves, andproving the contemporaneous existence in this island of both kinds of mammalia."
Fig. 111.Fig. 111.MEGACEROS HIBERNICUS.(Irish Elk.)
But the contents of the bone caves, consisting in large part of the extinct mammals, ought of themselves to be decisive in this question. As the opening of the Kirkdale cavern is only about four feet each way, a diluvial wave, charged with the wreck of the lower latitudes, could scarce have washed into such an orifice any considerable number of the intertropical animals. And yet there has been found in this cave,—with the teeth of a very young mammoth, of a very great tiger, of a tiger-like animal whose genus is extinct, of a rhinoceros, and of a hippopotamus,—the fragmentary remains of from two to three hundred hyænas. Further, even supposing, what is impossible, that a diluvial wave had swept them all from the tropics into the four-feet hole, on what principle is it to be explained that the bones thus washed into the cave should be all gnawed bones, even those of the hyænas themselves, whereas the bones of the same creatures found in the mammaliferous deposits of the country bear no marks of teeth? Mr. Granville Penn, however, gets over the difficulty of the cave, which is hollowed, I may mention, in a limestone of the Oolitic series, inclosing the ammonite and belemnite, by asserting that its mammaliferous contents may besomewhat older than itself! The limestone existed, he holds, as but a mere unformed pulp at the time the intertropical animals came floating northwards: they sank into it; the gasses evolved during putrefaction blew up the plastic lime above them into agreat oblong bubble, somewhat as a glass-blower blows up a bottle; and hence the Kirkdale cavern, with its gnawed bones and its amazing number of teeth. And certainly ageologicargument of this ingenious character has one signal advantage,—it is in no danger whatever of being answered by the geologists. Mr. Penn, in a second edition of his work, expressed some surprise that an Edinburgh Reviewer should have merely stated hisargumentwithout replying to it!!
But I need not dwell on the arguments for a universal deluge which have been derived from the superficial deposits. They all belong to an immature age of geologic science, and are of no value whatever. Let us pass rather to the consideration of the facts and arguments which militate against the universality of the catastrophe.
The form and dimensions of Noah's ark are definitely given in the sacred record. It seems to have been a great oblong box, somewhat like a wooden granary, three stories high, and furnished with a roof apparently of the ordinary angular shape, but with a somewhat broader ridge than common; and it measured three hundred cubits in length, fifty cubits in breadth, and thirty cubits in height. A good deal of controversy has, however, arisen regarding the cubit employed; some holding, with Sir Walter Raleigh, and most of the older theologians, such as Shuckford and Hales, that the Noachian cubit was what is known as the common or natural cubit, "containing," says Sir Walter, "one foot and a half, or a length equal to that of the human fore-arm measured from the sharp of the elbow to the point of the middle finger;" others contending that it was the palm-cubit, "which taketh," adds my authority, "one handful more than the common;" yet others, the royal or Persian cubit of twenty-one inches; and so on; for there are, it seems, fiveseveral kinds of cubit to choose from, all differing each from the others. The controversy is one in which there is exceeding little footing for any party. I am inclined, however, to adopt, with Raleigh and Hales, thenaturalcubit, for the following reason. The given dimensions of the ark form the oldest example of measurement of which we have any record; and all, or almost all, the older and simpler standards of measure bear reference to portions of the human frame. There is the span, the palm, the hand-breadth, the thumb-breadth (or inch), the hair-breadth, and thefoot. The simple fisherman on our coasts still measures off his fathoms by stretching out both his arms to the full; the village sempstress still tells off her cloth-breadths by finger-lengths andnails; the untaught tiller of the soil still estimates the area of his little field bypacing along its sides. Man's first and most obvious expedient, when he sets himself to measure, is to employ his own person as his standard; and the first or common cubit was a measure of this natural description equal in length to the extended fore-arm and hand. All the other cubits were artificial compounds of after introduction; and so, in the absence of direct evidence on the point, I accept the most natural and oldest cubit as in all probability the one employed in the oldest recorded piece of cubit measurement. And the ark, if measured by the common or natural cubit, must have been a vessel four hundred and fifty feet in length, seventy-five feet in breadth, and forty-five feet in height. Dr. Kitto, however, though we find him remarking that in computations of Scripture measures the cubit may be regarded as half a yard (Sir Walter's estimate), adopts, in his own computation of the size of the ark, without assigning any reason why, the palm-cubit, or cubit of twenty-one inches and nearly nine lines (21.888 inches); and, waving all controversyon the question, let us, for the argument's sake, admit the larger measure. Let us,—however much inclined to hold with Raleigh, Shuckford, and Hales,—agree with Dr. Kitto that the ark was five hundred and forty-seven feet in length, by ninety-one feet in breadth. Such dimensions, multiplied by three, the number of stories in the vessel, would give an area equal to about one seventh that of the great Crystal Palace of 1851. Or, to take a more definite illustration from the same vast building, the area of the three floors of the ark, taken together, would fall short by about twenty-eight thousand square feet of that of the northern gallery of the Palace, which measured one thousand eight hundred and forty-eight feet in length, by ninety-six feet in breadth. And thus, yielding to our opponents their own large measurements, let us now see whether the non-universality of the deluge cannot be fairly predicated from the dimensions of the ark.
I may first remark, however, that measures so definite as those given by Moses (definite, of course, if we waive the doubt regarding the cubit employed) were effectual in setting the arithmeticians to work in all ages of the Church, in order to determine whether all the animals in the world, by sevens and by pairs, with food sufficient to serve them for a twelvemonth, could have been accommodated in the given space. It was a sort of stock problem, that required, it was thought, no very high attainments to solve. Eighty years have not yet passed since kind old Samuel Johnson, in writing to little Miss Thrale a nice little letter, recommending her to be a good girl, and to mind her arithmetic, advised her to try the ark problem. "If you can borrow 'Wilkins' Real Character,'" we find him saying to the young lady, "a folio which perhaps the booksellers can let you have, you will have a very curious calculation,which you are qualified to consider, to show that Noah's ark was capable of holding all the known animals of the world, with provision for all the time in which the earth was under water." Unluckily, however, though the dimensions of the ark were known, the animals of the world were not; and so the question, in at least one of its terms, had to be very frequently restated. Let us take it as we find it presented (drawn, however, from a much older source), in Sir Walter Raleigh's magnificent "History of the World." "If in a ship of such greatness," says this distinguished man, "we seek room for eighty-nine distinct species of beasts, or, lest any should be omitted, for a hundred several kinds, we shall easily find place both for them and for the birds, which in bigness are no way answerable to them, and for meat to sustain them all. For there are three sorts of beasts whose bodies are of a quantity well known; the beef, the sheep, and the wolf; to which the rest may be reduced by saying, according to Aristotle, that one elephant is equal to four beeves, one lion to two wolves, and so of the rest. Of beasts, some feed on vegetables, others on flesh. There are one-and-thirty kinds of the greater sort feeding on vegetables, of which number only three are clean, according to the law of Moses, whereof seven of a kind entered into the ark, namely, three couples for breed, and one odd one for sacrifice; the other eight-and-twenty kinds were 'taken by two of each kind; so that in all there were in the ark one-and-twenty great beasts clean, and six-and-fifty unclean; estimable for largeness as ninety-one beeves; yet, for a supplement (lest, perhaps, any species be omitted), lot them be valued as a hundred and twenty beeves. Of the lesser sort feeding on vegetables were in the ark six-and-twenty kinds, estimable, with good allowance for supply, as fourscore sheep. Of those which devour flesh were two-and-thirty kinds, answerableto threescore and four wolves. All these two hundred and eighty beasts might be kept in one story or room of the ark, in their several cabins; their meat in a second; the birds and their provision in a third, with space to spare for Noah and his family, and all their necessaries." Such was the calculation of the great voyager Raleigh,—a man who had a more practical acquaintance withstowagethan perhaps any of the other writers who have speculated on the capabilities of the ark; and his estimate seems sober and judicious. It will be seen, however, that from the vast increase in our knowledge of the mammals which has taken place since the age in which the "History of the World" was written, the calculation which embraced all the eighty-nine known animals of that time would embrace those of but a single centre of creation now; and that the estimate of Sir Walter tells, in consequence, on the side, not of a universal, but of a partial deluge.
As man extended his acquaintance with the mammals, he found their number greatly increasing on his hands. Button, like Raleigh, though a professed naturalist, and a writer of admirable genius, had no very distinct notions of species. He was inclined to question whether even the ass might not be merely a degraded horse; and confounded many of the mammals of the New World with their representative congeners in the Old. And yet, in summing up his history of the mammaliferous division, he could state, that though it included descriptions of "a hundred and thirty-four different species of creatures that suckled their young, many of which had not been observed or described before," it was necessarily incomplete, as there were still others to add to the list, for whose history there existed no materials. At the same time he remarked, however, that the "number of quadruped animals whose existence is certain and well established does not amount to morethan two hundred on the surface of the known world." Yet here was the extreme estimate made by Raleigh, with what he deemed large allowance for the unknown animals, fairly doubled; and under the hands of more discriminating naturalists, and in the inevitable course of discovery, the number has so enormously increased, that the "eighty-nine distinct species" known to the great voyager have been represented during the last thirty years by the one thousand mammals of Swainson's estimate, the one thousand one hundred and forty-nine mammals of Charles Bonaparte's estimate, the one thousand two hundred and thirty mammals of Winding's estimate, and the one thousand five hundred mammals of Oken's estimate. In the first edition of the admirable "Physical Atlas" of Johnston (published in 1848) there are one thousand six hundred and twenty-six different species of mammals enumerated; and in the second edition (published in 1856), one thousand six hundred and fifty-eight species. And to this very extraordinary advance on the eighty-nine mammals of Raleigh, and the two hundred mammals of Buffon, we must add the six thousand two hundred and sixty-six birds of Lesson, and the six hundred and fifty-seven reptiles of Charles Bonaparte; or at least,—subtracting the sea snakes, and perhaps the turtles, as fitted to live outside the ark,—his six hundred andforty-tworeptiles.[29]
Such is the number of the known vertebrates, exclusive of the fishes, with which in this question we have now to deal. Still, however, there are a few lingering theologians, some of them very intelligent men, who continue to regard the ark as quite big enough for them all. Dr. Hamilton of Mobile, for instance, after fairly stating Swainson's estimate, namely, one thousand mammalia, six thousand birds, and one thousand five hundred reptiles and amphibiæ, goes on to say, that "it must not be forgotten, that of all these, the vastly greater proportion are small; and that numbers of them could be placed together in the same compartment of the ark." This, however, permit me to say with all respect, is not meeting the real difficulty. No doubt many of the birds are small,—many of the reptiles are small,—many even of the mammals are small,—many small animals were known in the days of Raleigh, and a much greater number of small animals are known now; but the question proper to the case seems to be, What proportions do both the large and the small animals now known bear to the large and small animals known in the days of Raleigh or Buffon; and how much additional accommodation-room would they require during their supposed voyage of a twelvemonth? There are two different ways in whichthe list of the known animals has been increased, especially of the known mammals. They have been increased in a certain appreciable proportion bydiscovery; and as discovery has been made chiefly in islands,—for the great continents had been previously known,—and as the mammals of islands, as has been well remarked by Cuvier, are usually small, of this appreciable proportion the bulk is comparatively not great. The great kangaroo (Macropus giganteus), though the inhabitant of an island which ranks among the continents, would not much exceed in bulk, tried by Raleigh's quaint scale of measurement, a sheep and a half, or at most two sheep; and yet I know not that discovery in the islands has added a larger animal to the previously known ones than the great kangaroo. Mr. Waterhouse, when he published, in 1841, his "History of the Marsupialia," reckoned up one hundred and five distinct species of pouched animals; and eighteen species more,—in all one hundred and twenty-three,—have been since added to the order. With the exception of an opossum or two, all these marsupiata may be regarded as discoveries made since the time of Buffon; most of them, as I have said, are small. And such, generally, has been the nature of the revelations made during the last seventy years by positivediscovery. It is not, however, by discovery, but by scientific scrutiny into the true nature and distinctions of species, that the recent enormous increase in the number of the known mammals has mainly taken place. And in these cases it will generally be found that the new species, which had been previously confounded with some old ones, so nearly resemble the latter in bulk, as well as aspect, as to justify in some degree the mistake. Let us take two of the greatest animals as examples,—the elephant and the rhinoceros. Buffon confounded the African with the Asiatic elephant. We now know that they representtwo well marked species,Elephas AfricanusandElephas Indicus; and that an ark which contained the ancestors of all the existing animals would require to have itstwopair of elephants, not the one pair only which would have been deemed sufficient eighty years ago. Again, with respect to the rhinoceros, Buffon was acquainted with the single horned animal, and hadheardof the animal with two horns; and so, though by no means certain that the "varietywas constant," he yet held that "two distinct species might possibly be established." But we now know that there are six species of rhinoceros (seven, according to the "Physical Atlas,")—Rh. Indicus,Rh. Javanus,Rh. Sumatrensis,Rh. Africanus,Rh. simus, andRh. ketloa; and that, instead ofpossiblyfour, at least twelve, or more probably fourteen, animals of the genus would require, on the hypothesis of a universal deluge, to have been accommodated in the ark. Buffon even held that the bison of America might be identical with not simply the auroch of Europe, which it closely resembles, but with even the European ox, which it doesnotresemble. But it is now known, that while the European aurochs are provided by nature with but fourteen pairs of ribs, the American bison is furnished with fifteen. Of each of the ruminants that divide the hoof, there weresevenintroduced into the ark; and it may be well to mark how, even during the last few years, our acquaintance with this order of animals has been growing, and how greatly the known species, in their relation to human knowledge, have in consequence increased. In 1848 (in the first edition of the "Physical Atlas") Mr. Waterhouse estimated the oxen at thirteen species; in 1856 (in the second edition) he estimates them at twenty. In 1848 he estimated the sheep at twenty-one species; in 1856 he estimates them at twenty-seven. In 1848 he estimated the goats at fourteen species; in 1856 he estimates themat twenty. In 1846 he estimated the deer at thirty-eight species; in 1856 he estimates them at fifty-one. In short, if, excluding the lamas and the musks as doubtfullyclean, tried by the Mosaic test, we but add to the sheep, goats, deer, and cattle, the forty-eight species of unequivocallycleanantelopes, and multiply the whole by seven, we shall have as the result a sum total of one thousand one hundred and sixty-two individuals,—a number more than four times greater than that for which Raleigh made provision in the ark, and considerably more than twice greater than that provided for by the students of Buffon. Such is the nature and amount of the increase which has taken place during the last half century in the mammaliferous fauna. In so great a majority of cases has it increased itsbulkin the ratio in which it has increased its numbers, that if one ark was not deemed more than sufficient to accommodate the animal world known to the French naturalist of eighty years ago, it would require at least from five to six arks to accommodate the animal world known in the present day.
Even in the days of Buffon, however, and at a still earlier period, the ark, regarded as a natural means of preservation from death bydrowning, was usually coupled, in the case of at least the carnivorous animals, with certain miraculous provisions against death bystarving. It seems to have been generally taken for granted, that the flesh-eating animals, when introduced to the shelter of the ark, entirely changed the nature indicated by their form of teeth, the character of their stomachs, and the shortness of their bowels, and fed, for the time they remained in it, exclusively on vegetable substances, which, in ordinary circumstances, their lacteals could not have converted into chyle. Certain figurative expressions in Scripture taken literally, which refer to a class of wild animals whose real destiny israther, it would seem, to be extirpated than to be changed, coupled with the belief, now no longer tenable, that there was a time, ere man had sinned, when there was no death among the inferior creatures, and of course no eaters of flesh, rendered the belief easy of reception; but it involved a miracle nowhere recorded; and the burden of the proof that such a miracle actually took place in the circumstances lies of necessity on the assertors of a universal deluge. Further, of even the creatures that live on vegetables, many are restricted in their food to single plants, which are themselves restricted to limited localities and remote regions of the globe. Dr. Hamilton has not referred, in his list of animals, to the insects,—a class which, though they were estimated in 1842 to consist of no fewer than five hundred and fifty thousand species, might yet be accommodated in a comparatively limited space. But how extraordinary an amount of miracle would it not require to bring them all together into any one centre, or to preserve them there! Many of them, like the myriapoda and the thysanura, have no wings, and but feeble locomotive powers; many of them, such as the ephemera and the male ants, live after they have got their wings only a few hours, or at most a few days; and there are myriads of them that can live upon but single plants that grow in very limited botanic centres. Even supposing them all brought into the ark by miracle as eggs, what multitudes of them would not, without the exertion of further miracle, require to be sent back to their proper habitats as wingless grubs, or as insects restricted by nature to a few days of life! Or, supposing the eggs all left in their several localities to lie under water for a twelvemonth amid mud and debris,—though certain of the hardier kinds might survive such treatment, by miracle alone could the preponderating majority of the class be preserved. And be it remembered,that the expedient of having recourse to supposititious miracle in order to get over a difficulty insurmountable on every natural principle, is not of the nature of argument, but simply an evidence of the want of it. Argument is at an end when supposititious miracle is introduced.
But the very inadequate size of the ark, though a conclusive proof that all, or nearly all, the progenitors of our existing animals could not have harbored within it from any general cataclysm, does not furnish a stronger argument against the possibility of any such assemblage, than the peculiar manner in which we now find these animals distributed over the earth's surface. Linnæus held, early in the last century, that all creatures which now inhabit the globe had proceeded originally from some such common centre as the ark might have furnished; but no zoologist acquainted with the distribution of species can acquiesce in any such conclusion now. We now know that every great continent has its own peculiar fauna; that the original centres of distribution must have been, not one, but many; further, that the areas or circles around these centres must have been occupied by their pristine animals in ages long anterior to that of the Noachian Deluge; nay, that in even the latter geologic ages, they were preceded in them by animals of the same general type. There are fourteen such areas or provinces enumerated by the later naturalists. It may be well, however, instead of running any risk of losing ourselves amid the less nicely defined provinces of the Old World, to draw our illustrations from two and a half provinces of later discovery, whose limits have been rigidly fixed by nature. "The great continents," says Cuvier, "contain species peculiar to each; insomuch that whenever large countries of this description have been discovered, which their situation had kept isolated from the rest of the world, the class of quadrupedswhich they contained has been found extremely different from any that had existed elsewhere. Thus, when the Spaniards first penetrated into South America, they did not find a single species of quadruped the same as any of Europe, Asia, or Africa. The puma, the jaguar, the tapir, the cabiai, the lama, the vicuna, the sloths, the armadilloes, the opossums, and the whole tribe of sapajous, were to them entirely new animals, of which they had no idea. Similar circumstances have recurred in our own time, when the coasts of New Holland and the adjacent islands were first explored. The various species of kangaroo, phascolomys, dasyurus, and perameles, the flying phalangers, the ornithorynchi, and echidnæ, have astonished naturalists by the strangeness of their conformations, which presented proportions contrary to all former rules, and were incapable of being arranged under any of the systems then in use." New Zealand, though singularly devoid of indigenous mammals and reptiles,—for the only native mammal seems to be a peculiar species of rat, and the only native reptile a small, harmless lizard,—has a scarce less remarkable fauna than either of these great continents. It consists almost exclusively of birds, some of them so ill provided with wings, that, like thewikaof the natives, they can only run along the ground. And it is a most significant fact, that both in the two great continents and the New Zealand islands there existed, in the later geologic ages, extinct faunas that bore the peculiar generic characters by which their recent ones are still distinguished. The sloths and armadilloes of South America had their gigantic predecessors in the enormous megatherium and mylodon, and the strongly armed glyptodon; the kangaroos and wombats of Australia had their extinct predecessors in a kangaroo nearly twice the size of the largest living species, and in so huge a wombat, that itsbones have been mistaken for those of the hippopotamus; and the ornithic inhabitants of New Zealand had their predecessors in the monstrous birds, such as the dinornis, the aptornis, and the palapteryx,—wingless creatures likethe ostrich, that stood from six to twelve feet in height. In these several regions twogenerationsof species of the genera peculiar to them have existed,—the recent generation by whose descendants they are still inhabited, and the extinct gigantic generation, whose remains we find locked up in their soils and caves. But how are such facts reconcileable with the hypothesis of a universal deluge?
