ALTHOUGH I have stated the plan of this work in a full title-page, and have more- over somewhat enlarged upon it in the Introduction, there seems to me still a propri- ety in, if not a necessity for, a few detailed remarks, by way of Preface. A little reflection will satisfy any one that my undertaking in these pages is a difficult, if not a hazardous one. I seek to comprise a subject of vast, nay, boundless extent, within the narrow compass of two volumes; I endeavor to reconcile something of the stern- ness of science with the license of the describer, the narrator, and the anecdotist; I place myself between the Scylla of scientific naturalists on one side, and the Charybdis of popular taste on the other. Therefore, even if a preface be, as is generally held, , an author's weakness, I ask the kindly indulgence usually extended to these perform- ances, inasmuch as they are regarded like the plea of a criminal at the bar, and the Public would not pronounce judgment without giving him a hearing. At the outset, then, I beg to say that this book is not designed for the benefit of scientific naturalists, and yet I hope to obtain their approbation, however defective and deficient it may appear in their view. It is written for the great mass of readers, who have not the means of purchasing the hundreds and thousands of volumes in which the History of Animated Nature is now embodied; for those who do not under- stand the technicalities of science, and who are, as a matter of necessity, driven from I vi PREFACE. 3 a the pursuit of it by the difficulties with which it is encompassed; for those, in short, who have not time, opportunity, or capacity for scientific research. My design is—while maintaining a systematic arrangement, or in other words, a scientific classification- still to present the subject in a form so simple, and so far divested of technicalities, that any person of common education may read it, understand it, and profit by it. The ultimate object of Natural History is not to furnish an array of hard names in the form of a complicated classification ; these, so dear, so significant to the scientific student, are only the means and instruments by which certain practical results are to be attained. They are the skeleton : the blood, the flesh, the palpitating life, consist in what is perfectly appreciable by common minds—the wonderful structure, the beau- tiful adaptations, the amazing instincts, the admirable powers, the interesting quali- ties, the prodigious diversities of form, to be traced in the Animal Kingdom. These are revelations which expand the mind, elevate the heart, and inevitably lead the student of nature up to nature's God. These are the beneficent fruits of science; they are the practical results of the profound and toilsome researches of scientific men; and yet, but for some such work as this now presented to the public, they must remain beyond the reach of the million, locked up in quartos, hidden in the libraries of the learned, or at best, seen darkly and confusedly in the dizzying mist of long Greek and Latin names. My task, in comparison with that of those who explore and discover scientific facts, and even of those who merely assign them to their places in the gallery of science, is a humble one, and yet it seems to me necessary to be accomplished, in order to make the world at large participators in the golden fruit of scientific research. I regard myself as a simple interpreter of the language of the gods of science, seeking to make it familiar to this lower world of common men. In this I hope to render a practical hom- age to science and scientific men, and not merely to make the generation of the living and breathing present share in the fruit of their researches, but to beget a taste for science in the rising generation, and thus-through popular exhibitions of its inter- esting and useful facts—in the end to train up naturalists who will hereafter them- selves contribute to the enlargement of the boundaries of science, and thus make the stupendous labors of those who have gone before, and accumulated the immense mass of truths now embodied in the subject, productive of a double harvest. Therefore it is that, regarding my labors as thus subsidiary to the works of scientific naturalists, I hope for their approbation. There is another and still larger view of this subject. The Natural History of An- imals is one of universal interest to mankind, alike from our constant connection with many of the species, and the curious and interesting facts which their structure, hab- its, and instincts unfold to the student of nature. It is a subject as full of poetry as of philosophy, of romance as of reason; and it has, moreover, been commended to the popular mind by two remarkable authors—Buffon, who wrote in French, and Gold- smith, who, in translating a portion of his works into our language, even adorned the 3 PREFACE. vii original.* Thus Animated Nature was popularized, at least in English, at once and forever. Even now, after the lapse of nearly a century, though science has overturned the systems on which these authors founded their writings, and has proved a multi- tude of their details to be either imperfect or fabulous, still their felicitous descriptions, their lively anecdotes, their fascinating narratives, continue to be published and repub- lished, as a never cloying feast, for generation after generation. Nor has this subject been less fortunate in its scientific treatment. Not to speak of Linnæus, who wrote a century ago, and whose great name can never be overshadowed by comparison, George Cuvier, the Master Mind of his age, though by no means neglect- ing the external qualities of animals, explored with a profound sagacity their internal structure. The result is well known—the new science of Comparative Anatomy, that has waked from their sleep of ages the multitudinous races of extinct animals; and furthermore, Cuvier's example has led to the study of the structure of existing races as the very basis of Scientific Zoology. And what an array of great names has since fol- lowed in his track! The general effect is an expansion of the science beyond the com- prehension of any single mind, and hence different authors have devoted themselves to special branches, one to insects, nay, often to a single genus of insects; another to reptiles; another to star-fishes ; another to the infusoria, and so on.t Often has the whole life of a great man been devoted to the study of a single family, even of the lower forms of life; and this, after all his studies, has been found to have depths yet unsounded. The amazing extent and wonderful developments resulting from these efforts are illus- trated in the recent work of Professor Agassiz—two volumes, quarto, upon American Tortoises—creatures that creep beneath our feet in the brooks and puddles, many of them familiar to us, all objects of general indifference or contempt, and yet the whole furnishing an example of the most profound research, the most beautiful adaptations, the most wonderful revelations: a theme in the hands of its master, fruitful of the most sublime and inspiring trains of thought. And what has been done in respect to this one class of animals, has been done with more or less ability and success, in respect to a multitude of others. Nor is this all. Travelers in modern times are naturalists, and those especially who have recently explored new countries, have brought to the general stock a vast mass a * Goldsmith's "Animated Nature” was not an express translation of Buffon; it was, to a great extent, original; still he followed in Buffon's footsteps, and in some cases translated and in others paraphrased him. When Dr. Johnson was informed that Goldsmith had undertaken this work, he remarked, "He will make it entertaining as a Persian tale;" and Irving, in his life of Goldsmith, says the prediction was fulfilled. + As an illustration of special study in Natural History, we may mention the Oology of the Birds of North America, by Dr. T. M. Brewer, whose name is so often mentioned by Audubon, Nuttall, &c., as having furnished them with useful ornithological facts. This work, which will make a quarto volume of a thousand pages, is soon to appear under the auspices of the Smithsonian Institution. It will initiate a new branch of study in ornithology, as furnishing the best possible means of determining the species and geographical range of particular genera of birds. viii PREFACE. of interesting materials for Natural History. The whole Australian world has been made known in our day, and it has furnished its Ark of Beasts and Birds and Creep- ing Things-curious, strange, and wonderful—its birds alone filling seven volumes folio! The navies and armies of every civilized nation have now their corps of nat- uralists, and even the Explorations for a Railroad to the Pacific—a stupendous project, and worthy of great and good results-give to the world whole quartos of the most profound scientific research in respect to our local zoology.* And hence it is that the treatises on Natural History amount to entire libraries. The works consulted by Professor Baird, in the compilation of his Mammals and Birds of North America, are in every language of Europe, and comprise, I believe, over two thousand vol- umes; and all this in addition to his examination of specimens. Such is the vast ex- tent of this subject as presented in the books! And yet, notwithstanding this affluence of materials, and this grandeur to which the subject has been elevated by the combined labors of the civilized world; notwith- standing its inherent interest, and its general popularity through traditional associa- tions with eminent writers of the past century, it is a remarkable fact, that there is not, in this country, a single publication which even pretends to give a popular view of the Animal Kingdom, as science now presents it. It is to be observed, that nearly all these works which we have mentioned are strictly scientific, and at the same time special, and, in view of the whole science, fragmentary. It is true that in England, France, and more particularly in Germany, there are many popular treatises on Natural History, but these for the most part are confined to particular branches of science—one to birds, another to quadrupeds, another to insects, and another to mol- lusca, &c. Some of our state governments have caused works on zoology to be pub- lished, such as that of New York, issued under the superintendence of Dr. De Kay, that of Massachusetts, by Dr. Storer and others, and that of Ohio, by Dr. Kirtland; but even these clever works are not only in mere outline, but they are local and partial. No one, at least in the English language, has recently ventured upon the attempt to present the whole subject in a comprehensive, popular form. There are condensed scientific outlines, indeed, but these are little more than expanded cata- logues or classifications of the whole science, and one of them—that of Dr. Chenu, for instance, now near its completion in Paris—comprises ten volumes quarto! The cele- brated classification of the Genera of Birds, by G. R. Gray, published in London in 1849, comprises three volumes quarto, and costs one hundred and fifty dollars ! There are also other works giving abridged skeletons or outlines of the whole field; but one suited to the people, or even designed for the general reader, does not exist * See the two volumes on the Mammalia and Birds of North America, by Professor Baird, of the Smithsonian Institution, and just issued among the documents of the United States Senate; these to be followed by a third volume on Reptiles. PREFACE. ix a a in our language.* And yet the desirableness, nay, the necessity of such a work, is obvious, but who shall attempt to popularize a subject so vast, so boundless ? No one has entered upon a task so formidable, if not so hopeless. The audacity, or per- haps the folly, as it may prove, of attempting to supply this want, seems to have been reserved for the author of these pages. The immense extent of the subject is not the only, nor indeed the chief difficulty with which the compiler has to contend. The popular mind of our day—at least in this country—is too far advanced to be content with mere descriptions of isolated spe- cies; all know at least something of classification, and nearly all desire to know more. It would neither satisfy the public, nor be doing justice to the opportunity, in de- scribing animals, to neglect to show them in their relations to other animals. Every beast and bird and reptile and fish has its place in a chain of beings, and neither these individuals, nor the Mighty Plan of Creation, can be at all comprehended unless by treating each in connection with its affiliated genera. Classification, therefore-or in other words, a Systematic Arrangement-was indispensable; and inasmuch as all systems are expressed in technical terms, a considerable array of Greek and Latin words, so frightful to many readers, was inevitable. The scientific writer presumes that his readers understand Latin and Greek as well as their mother tongue. I write for a different class, and am bound to presume that they are not familiar with these languages. While, therefore, I am compelled to use them, I have sought to mitigate the difficulty by abundant explanations of technical terms. Nevertheless, the skeleton of system and classification remains, and I must reconcile with this, an abundance of details, descriptions, incidents. To hit upon a just balance between these necessities, may demand a nicer judgment than belongs to any man. That I have satisfied the requisitions of the scientific naturalist on the one side, and of the lovers of narrative, anecdote, and illustration, on the other, is indeed my hope, though hardly my expectation. If I am crushed between the two, I shall console myself as well as I may with the consciousness that the attempt was worthy of better a success. To these considerations I have little to add. I may be permitted, however, to no- tice particularly one principal feature of the work, and that is, the abundance of the engravings. It is admitted that pictures are the best describers of the forms of ani- mals. A single wood-cut will give a more accurate and indelible impression of the personal appearance and aspect of a lion, a giraffe, an eagle, or a hippopotamus, than whole pages of verbal description. I have known children, born and bred in the city, *"It is not to be overlooked," says Agassiz, in the preface to his "Contributions to the Natural History of the United States," "that while our scientific libraries are still very defective, there is a class of elementary works upon Natural History widely circulated in Europe, and accompanied with numerous illustrations, which are still entirely unknown in this country." * "There has not been published in the United States) a single text-book embracing the whole animal kingdom." X PREFACE. on going for the first time into the country, and seeing the milking of the cow, the plowing of the field, the scampering of the lambs, the gambols of the calf, the swim- ming of the ducks and geese, immediately recognize them as things they had seen in the humble but still speaking wood-cuts in their primers. I have frequently seen children, on going into a menagerie, name the principal beasts, though they had never seen one of them before; but they had become acquainted with them from the wood- cuts in their story-books. Every person must be familiar with similar evidences, derived from his own experience, of the effect of these unpretending illustrations. Wood engraving, for several reasons, is, indeed, especially adapted to popular works on Natural History. One is the greater economy, so that we are able in this work to give more than fourteen hundred portraits of animals. Another is, that from its nature it is very effective in the representation of feathers and hair, the integuments of birds and quadrupeds; it is hardly less adapted to the representation of the scales of fishes and the shells of mollusca. A still more important reason is, that these en- gravings are now universally made from drawings on the wood, and the engraver merely cuts out the lights, leaving the shades just as the designer drew them. There- fore, a wood engraving is a fac simile of the original design, and hence it is that these generally possess a spirit, life, and verisimilitude, even beyond many copper or litho- graphic engravings. The “English Cyclopedia of Natural History" asserts that the wood engravings in Bell's and Yarrell's Beasts and Birds of Great Britain and which, by the way, we have extensively copied in the following pages—are manifestly supe- rior, for the conveyance of accurate impressions of the aspects of animals, to some of the colored engravings in the more imposing books of science. The majestic air of the lion, the sly visage of the fox, the vivacity of the squirrel, the pertness of the wren, the crawling gait of the spider, and indeed all the characteristics of external , appearance in animals, except color-all those indeed which mere words cannot convey—are generally more successfully represented in fine wood engravings than in a any other. And finally, what is more important than all in a work like this, for the house and the home, and for daily use, these engravings-being in immediate contact with the descriptive text-are consulted without the trouble of referring to an index and turning over leaves, and are therefore more convenient and useful, as illustrations, than the ma- jority of steel and copper engravings, which are, of necessity, separated from the text. , It is hoped, therefore, that the numerous and clever engravings of this work-more ample than have ever appeared in any similar publication, and inserted, not as mere embellishments, but for the most part as descriptions of animals—may render it acceptable, even if in any other respects it may see may seem defective. It may be necessary to state the extent to which this work carries the notice of particular species of animals. As there are a quarter of a million of species in the Animal Kingdom, a very narrow selection for particular description must of course be PREFACE. xi I made. In the United States there are seven hundred known and described species of birds; more than five hundred recognized species of fish; several hundred mam- malia, and reptiles, insects, mollusca, and protozoa without number. In South Amer- ica, Mexico, and Central America, there are three hundred kinds of humming-birds, and according to Mr. Sclater, in the same regions there are nearly two hundred tana- gers, &c. In respect to other parts of the world the multiplicity of species is equally great. In choosing amid this multitudinous mass, I have endeavored to select for description the most remarkable species; and as all could not be noticed, I have chosen those which are representatives of large classes of analogous genera. may indicate the extent of particular descriptions by saying that I have noticed, with greater or less detail, all or nearly all the species of birds and quadrupeds in Audubon's great work on the Ornithology of North America; in the admirable works of Wilson and Nuttall ; in the excellent work of Audubon and Bächman on the quadrupeds of North Amer- ica; in the able reports of De Kay, Storer, and Kirtland on the zoology of New York, Massachusetts, and Ohio ; and in the more recent publication of Cassin on the birds of California, &c.—the only fault of which is its brevity. There is, therefore, I believe, no very important quadruped or bird, in the United States, not noticed here. It is true that there are some species which I have omitted, to be found in Baird's great and important national work on the Mammalia and Birds of North America, issued under the auspices of the government, to which I have already alluded; but these are chiefly of the smaller kinds, and generally belong to the remote and unexplored regions of our continent. The recent acquisitions of Texas, New Mexico, California, and Utah have brought within the bounds of the United States a vast extent of territory, and thus have greatly enlarged the circle of our national fauna; but all the important addi- tions, even within these new territories, have, I believe, a place in the following pages. In respect to other parts of the world, where the species are still more numerous and diversified, the scale of selection is more circumscribed; but still I believe no species of particular interest among the higher orders of animals, either in Europe, Asia, Africa, or Oceanica, has been omitted. That these volumes, while being primarily designed for popular reading, should also be suited for general reference, is manifest; and this necessity has not been disregarded. In the General Index, at the close of the second volume, references will be found, giving the popular and scientific names, and in most cases the form, size, color, and habitat of more than four thousand species, and these, it is hoped, will be a sufficient key to the whole field, however boundless, of the Animal Kingdom. Notwithstanding the multiplicity of species in the existing and living races of ani- mals, those which geology has unfolded to our view—the Dead Kingdom of Nature, doubtless as populous as the living—could not be overlooked. It is a stupendous fact, that in all the bones of these extinct generations, the same plan of organization is visible as that which governed the structure of the living races; thus showing that a xii PREFACE. the same Almighty Mind presided over Creation in ages so remote as to seem on the verge of a past eternity, as in that Adamic Creation which peopled a new and regen- erated world. The study of the relics of these lost races often throws great light on the present animal kingdom, and therefore the Natural History of to-day necessarily includes a reference to them. We have therefore, in these pages, given some general notices on this subject, which, with the curious engravings illustrating them, we hope may prove interesting and instructive. One thing more. In consideration of the frequent use of the French, German, and Italian languages in this country-owing alike to the great number of foreigners among us, the general enlargement of our literature, and the involving of whole territories within our bounds, to many of the people of which one or other of these is a native a tongue—we have given the popular names of prominent species of animals in these several languages. Finally, in view of the whole subject, considering its vast extent, its amazing reve- lations, its boundless details—curious, strange, wonderful, and all immediately and inevitably traceable to that God whom we worship, in whom we believe, hope, and trust–I cannot but feel that it is well worthy the earnest study of the wise and the simple, the learned and the unlearned. If I have placed it within the reach of an enlarged circle of readers, and if I have succeeded in commending it effectively to their attention, I shall feel that this, my patient labor of some years, has not been in vain.

In whatever direction we turn our eyes, we everywhere meet the varied forms of animal life. Earth, air, water, are all alike occupied by multitudes of living creatures, each fitted especially for the habitation assigned to it by nature. Every wood or meadow—nay, every tree or shrub, or tuft of grass—has its inhabitants; even beneath the surface of the ground, numbers of animals may be found fulfilling the purposes for which their species were called into existence. Myriads of birds dash through the air, supported on their feathered pinions, or solicit our attention by the charming song which they pour forth from their resting-places; while swarms of insects, with still lighter wings, dispute with them the empire of the air. The waters, whether salt or fresh, are also filled with living organisms; fishes of many forms and varied colors, and creatures of yet more strange appear- ance, swim silently through their depths, and their shores are covered with a profusion of polypes, sponges, starfishes, and other animals. "The sounds and seas, each creek and bay, With fry innumerable swarm, and shoals Of fish that with their fins and shining scales Glide under the green wave, in sculls that oft Bank the mid sea: part single, or with mate, Graze the sea-weed their pasture, and through groves Of coral stray; or sporting with quick glance, Show to the sun their waved coats dropped with gold; VOL.

To whatever elevation we attain on the mountain-sides, to whatever depth in the ocean we may sink the lead, everywhere shall we find traces of animal existence, everywhere find ourselves surrounded by living creatures, in a profusion and variety which may well excite our wonder and admiration. Nor are these phenomena confined to any region of the earth; on the contrary, the diversity of climate only adds to the variety of objects which the zoologist is called upon to contemplate. Thus the bold voyager of the inclement regions of the north, in losing sight of those productions of nature which met his eyes at home, finds, as it were, a new creation in his new abode,-seals, by the hundred, basking in the scanty rays of the Arctic sun, or diving into the deep waters in search of their finny prey,—the whale, rolling his vast bulk in the waves, and ever and anon driving high mto the air his curious fountain—water, be it remembered, strained from the myriads of small animals which constitute the food of the leviathan. The air is peopled by innumerable flights of marine birds; the sea by still more countless swarms of fishes; and the land affords a habitation to the elk and the reindeer, the Arctic fox, and other creatures peculiar to those regions. If we turn our regards southward, to the tropical regions of the earth, the abundance and variety of animated beings increase more and more. Here the colossal elephant and the unwieldy rhinoceros, crash through primeval forests ; the lion and the tiger, and other predatory beasts, prowl through the thickets, seeking for their prey; on vast plains, countless herds of antelopes browse in fancied security, or dash swiftly past at the approach of danger; gigantic snakes lie coiled in horrid folds among the bushes, or hang from the trees awaiting their victims. The air and trees swarm with birds of gorgeous plumage, and insects of strange forms and brilliant colors. Nor are the waters less bountifully provided with inhabitants : every form with which we are acquainted in our own seas is here represented, but with still greater profusion and variety. a * * * "Full nature swarms with life. Through subterranean cells, Where searching sunbeams scarce can find a way, Earth animated heaves. The flowery leaf Wants not its soft inhabitants. Secure Within its winding citadel, the stone Holds multitudes. But chief, the forest boughs, That dance unnumbered to the playful breeze, The downy orchard, and the melting pulp Of mellow fruit, the nameless nations feed Of evanescent insects. Where the pool Stands mantled o'er with green, invisible, Amid the floating verdure, millions stray. Each liquid too, whether it pierces, soothes, Inflames, refreshes, or exalts the taste, With varying forms abounds. Nor is the stream Of purest crystal, nor the lucid air, Though one transparent vacancy it seems, Void of their unseen people." And there is a feature in this abounding animal life of the sea, which strikes the mind as one of the most beautiful provisions of nature. At night, the ocean sparkles with a brilliancy which rivals the splendor even of a tropical sky; and this phenomenon, which may be witnessed, although in an inferior degree, in more temperate climes, is due to the presence of vast multitudes of minute phosphorescent animals, whose very existence would frequently remain unknown, but for their powers of illuminating the waves by night. And when we have exhausted the study of external nature, there is yet another world to which we may turn. Within our bodies, and those of every species of animal, from the highest to nearly the very lowest, exist various forms of parasites, preying upon our substance or our food: creatures INTRODUCTION. 3 whose very existence and development are a mystery—a mystery, however, which, as far as it has yet been unraveled, serves to raise our expectations as to what remains behind. As the telescope has revealed myriads of stars beyond the reach of unassisted sight, on account of their distance, so has the microscope unfolded countless generations of beings, as much beyond the reach of vision, on account of their littleness. When we are told that, in addition to what has been previously stated, eight hundred millions of living things may exist in a cubic inch of water, we begin to have some faint conception of the scope of our subject, to which is given the name of Zoology, or the SCIENCE OF ANIMAL LIFE. THE EQUILIBRIUM MAINTAINED AMONG ANIMAL TRIBES. Notwithstanding the variety in size, form, structure, and habits, amidst this profusion of animal life, a due balance of power and number is maintained by the influence of species upon species. They are destined to act and react upon each other by laws of destruction and renovation, through which the proportions of animal existence are preserved in just equilibrium. Multitudes are doomed to become the prey of others—whole races are created as though for slaughter; but, great as is the loss, the increase is equivalent, in order to the preservation of the species. As regards indi- viduals, the instinctive means of attack on the one hand, and of self-preservation on the other, are such as to equalize their respective chances. Speed, caution, watchfulness, inaccessible retreats, the nature of their clothing, and even its color, alike protect the timid and defenceless; while the bolder oppose force to force. Those that are most obnoxious to destruction, are the most prolific. Insects, for example, are the common prey of birds and beasts, reptiles and fishes, and often of each other; yet who has ever known their numbers perceptibly diminished? How great is the daily havoc among fishes! They are the prey of each other : the cachalot, the grampus, the por- poise, the otter, and the seal, devour them in multitudes: thousands of oceanic birds find in them their natural aliment, whilst man draws them by shoals from the deep; such, however, is their astonishing fecundity, that all these losses are duly repaired. The number of eggs in the roe of the codfish has been calculated to be 3,687,760; of the founder, 1,357,400; of the herring, 36,960; of the mackerel, 546,680; of the smelt, 38,280; of the sole, 100,360; of the tench, 383,250. Of an increase by numbers like these, no examples exist among the higher classes of vertebrata, viz., birds and mammalia : still, the law of the balance of increase and decrease is not the less established among them; hence we justly conclude, that each part of the creation depends upon another; and though, at a single glance, all may seem confusion, it will be found, upon mature reflection, that order and due equipoise of parts are the results of a scheme equally well а adapted and wisely ordained. a a ADVANTAGES OF THE STUDY OF NATURAL HISTORY. The advantages attending the study of such a subject as this are obvious. So many animals are directly or indirectly subservient to the necessities, pleasures, or luxuries of man, from so many does he experience direct or indirect injuries, that a knowledge of them is almost indispensable to his existence. Our table, our dress, our household furniture, and a variety of conveniences which we enjoy, will remind us, if we reflect for a moment, of a multitude of animals, which, in one way or other, are essential to our comfort ; and we may, with equal ease, form a catalogue of such as, on the contrary, are injurious to our welfare. But, leaving out of the question the necessity thus imposed upon us of gaining a general knowledge of natural objects, we may observe, that the study of natural history is peculiarly fitted for strengthening and enlarging the mind. It disci- plines the memory; it demands the exercise of patient investigation ; it enforces an attention to minutiæ; it leads us to detect differences, where none but the practiced eye would perceive them, and to trace out analogies, or affinities, which reflection alone can discover. Its aim is truth; and so far, it must be a noble and elevating pursuit. If to correct the imagination, and strengthen the powers of reason, be among the advantages attending the study of the exact sciences, not less beneficial are the results attending the study of Nature. Yet, independently of this consideration, Nature holds out other motives to excite our interest; she asserts her intrinsic value, and, while claiming our admiration of her work, speaks of unerring Wisdom and almighty Power. 4 ILLUSTRATED NATURAL IIISTORY, 66 THE TEACHINGS OF NATURAL HISTORY. “ To every man,” says Martin, from whom we derive some of the preceding suggestions, “whose heart is well attuned, whose feelings are pure and undebased, Nature presents a thousand charms.

The result is an accumulated mass of riches, which, transmitted to our immediate successors, may be by them assayed, refined, and increased, and, in due order, passed on to generations following." THE MYSTERY OF LIFE. a It is quite true, that after all the researches of philosophers, one question of vital interest remains unanswered: What is Life? There is a mystery behind that little word, says Gosse, which no one has yet been able to solve. Science, with the experience of ages, with all the appliances of art, and with all the persevering ingenuity and skill that could be brought to bear upon it, has ardently labored to lift the veil; but philosophy, and science, and art stand abashed before the problem, and confess it a mystery still. The phenomena, the properties of life, are readily observ- able. We take a bird in our hands : a few moments ago it was full of energy and animation; it shook its little wings as it hopped from perch to perch; its eyes glanced brightly, and its throat quivered as it poured out the thrilling song which delighted us. Now the voice has ceased, the eye is dim, the limbs are stiffening, and we know that it will move no more. Chemical changes have already begun to operate upon its organs ; decomposition is doing its work, and soon the beautiful little bird will be a heap of dust. We say that its life has gone; but what is it that has gone? If we put the body in the most delicate balance, it weighs not a grain less than when it was alive; if we measure it, its dimensions are precisely the same; the scalpel of the anatomist finds all the constituent parts that made the living being; and what the mighty principle is, the loss of which has wrought such a change, alike eludes research and baffles conjecture. We are compelled here to recognize the Great First Cause, and to rest in the reverent declaration, “ In Him we live, and move, and have our being." The researches of modern science, however, aided by the inventions which it has brought into existence, though they have been unable to throw a single ray of light on the nature of Life itself, have yet done much to make us familiar with its phenomena. It is a material part of the design of the present volume to acquaint the reader with the more interesting portion of these results. OBJECT AND SOURCES OF THE PRESENT WORK. The plan of the author is to give a popular compend of the Natural History of the Animal Kingdom, as it is now found in publications of a professed scientific character. In doing this, he will necessarily lay under contribution the works of the great masters in zoological science, as Linnæus, Cuvier, and Buffon; together with those of numerous authors, distinguished in spe- cial branches, as Gervais, Le Maout, T. Rymer Jones, Milne Edwards, Gould, Bell, Yarrell, Forbes, Dallas, Agassiz, Bennett, Newman, Martin, Nuttall, Wilson, Audubon, Bonaparte, and many others ; besides the productions of a multitude of travelers who have incidentally described the animal productions of the various countries they have visited. To them, whatever there may be of actual discovery in the following pages, must be credited. The author, however, will be particularly indebted for many lively descriptions of animals to two recent Paris publications on the Garden of Plants, and the two volumes on the Garden and Menagerie of the Zoological Soci- ety of London, both illustrated by many clever, because life-like, engravings. It is to the two noble institutions which have given birth to these works, that the world is indebted for a sort of personal acquaintance with many of the rarest and most curious specimens of the animal kingdom, and also for accurate descriptions of a great number of exceedingly interesting animals—birds, beasts, and reptiles; thus, in many cases, dissipating errors which had lingered in works of natural history for hundreds of years.* * During my late residence in Paris, the “Garden of Plants” was my favorite resort, not only as a means of study- ing Natural History, but for the purpose of enjoying its beautiful walks and charming views. The interest thus excited in my mind has led me to undertake the present volume, which I shall be able to enrich by numerous en- gravings of animals belonging to that celebrated seat of science. The establishment of a similar institution in one of the great cities of the United States, would be worthy the exertions of our wealthy and cnlightened citizens. INTRODUCTION. 7 GEOLOGICAL REVELATIONS. However vast and varied may be the view suggested to the mind by a glance at the animal kingdom, as it exists at the present day, there is still something beyond even this. Geology has revealed to us the startling fact that immense numbers of animals, of species entirely dis- tinct from those of which we are to give an account, have once flourished upon the earth; and, having ful- filled their destiny, have ceased to exist, leaving no trace of their history, except their vestiges in the soils and rocks which constitute the crust of the globe. Of these extinct animals, there were whole races, some of strange and uncouth forms, some of enormous magnitude, some resembling the existing types, and others which have left no living representatives upon the earth. In our own country, the bones of an enormous animal, resembling the elephant, have frequently been found, to which the name of mastodon has been given. In the mountains of India have been found the bones of an ani- mal larger than the rhinoceros, having four horns and a proboscis. On this has been bestowed the name of sivathe- rium. In the pampas of South America, scattered over an extent of six hundred miles, have been discovered the remains of an animal of the dimensions of an elephant, yet combining the peculiarities of the sloth and the ant-eater. This extraordinary creature has been called the megatherium. The dinotherium, whose bones have been met with in France and Germany, was larger even than the mastodon, and formed a striking resemblance to the tapir. LOSSIN ARRITI 8. ILLUSTRATED NATURAL HISTORY. Among the amphibious animals, there were creatures of still more extraordinary proportions. One of these, the ichthyosaurus, was a fish-lizard, with the teeth of a crocodile, the head of a lizard, and the fins of a whale. The plesiosaurus was similar, but still more remarkable. Cuvier asserts that its structure was altogether monstrous. To the head of the lizard it united the teeth of the crocodile, with a neck of enormous length resembling the body of a serpent; it had a trunk and tail of the proportions of an ordinary quadruped, with paddles similar to those of the turtle or whale. Twenty species of this have been discovered, having a general structure like that of the ichthyosaurus. A skeleton is to be seen in the British Museum, eleven feet long, and so nearly perfect, that the form of the original creature may be readily traced. It was probably carniv- orous, and lived in shallow seas and estuaries, and breathed the air like the ichthyosaurus and our modern cetacea. The vertebræ of the neck are about thirty-three, equal to those of the longest-necked bird, the swan. This neck was probably of great use in aiding it to seize upon fish beneath the waters, and perhaps flying reptiles and insects. Its tail was so short that it could not have been used, like the tail of fishes, to impel the creature rapidly forward, but was doubtless employed employed as a rudder to steer him when swimming, as well as to raise or depress him when ascending or descending in the water. Mr. Conybeare, after considering all the character- istics of the animai, draws the following inferences with respect to the habits of the plesiosaurus. “ That it was aquatic, is evident from the form of its paddles; that it was marine is almost equally so, from the remains with which it is universally associated; that it may have occasionally visited the shore, the resemblance of its extremities to those of the turtle may lead us to conjecture; its motion, however, must have been awkward on land, and its long neck must have impeded its progress through the water,--presenting a striking contrast to the organization which so admi- rably fitted the ichthyosaurus to cut through the waves. May it not, therefore, be concluded-- since, in addition to these circumstances, its respiration must have required a frequent access of air—that it swam upon or near the surface; arching its long neck like the swan, and occasion- ally darting it down at the fish which happened to float within its reach? It may, perhaps, have lurked in shoal water along the coast, concealed among the sea-weed, and, raising its nostrils to a level with the surface from a considerable depth, have found a secure retreat from the assaults of dangerous enemies." The iguanodon, whose bones were found in the soil of Tilgate forest, England, was of altogether more monstrous proportions, its length having been probably nearly fifty feet. It was, in fact, a gigantic lizard, bearing a resemblance to the iguana of Brazil. It is supposed that such an animal could only have existed in a hot country, and hence it is concluded that a torrid climate once prevailed in England. The large bones of the iguanodon having been evidently filled with marrow, this, with the form of the bones of the feet, shows that the animal was adapted and designed to move on the land. Its teeth, also, prove that they were remarkably fitted for cropping tough vegetable food, such as the clatharia, and similar plants, which are found buried with its bones. As the iguana lives chiefly upon vegetables, it is furnished with long and slender feet, by which it is enabled to climb trees with facility in search of food; but no tree could have borne the weight of the colossal iguanodon. Its movements must have been confined to the land and water, and it is evident that its enormous bulk must have required limbs of great strength. Accordingly, we find that the hind feet, as in the hippopotamus, rhinoceros, and other large mam- malia, were composed of strong, short, massy bones, furnished with claws,--not hooked, as in the iguana, but compressed, as in land tortoises; thus forming a powerful support for the enormous leg and thigh. But the bones of the hands or fore-feet are analogous to those of the iguana,—long, slender, flexible, and armed with curved claws; thus furnishing prehensile instruments fitted to seize the palms, arborescent ferns, and dragon-blood plants, which probably constituted the food of the iguanodon. Another of these fossil mammals was the pterodactyle, whose bones were of such strange con- formation, that the first specimen discovered was classed by one naturalist as a bird, by another as a species of bat, and by yet a third as a flying reptile. The creature, indeed, combined certain characteristics of all three. The head, and the length of the neck, resemble those of a bird; its wings, in proportion and form, are like those of the bat; while the body and tail approximate in INTRODUCTION. 9 ci 82224 REDMALSO LI EXTINCT ANIMALS. structure to the body and tail of the mammalia. The skull, also, is small, the head being furnished with a beak which has not less than sixty pointed teeth. These singular characteristics, so puz- zling to investigators, it was reserved for the genius of Cuvier to reconcile. He ranks the ptero- dactyles among the most extraordinary of all extinct animals; and if we could see them restored to life, they would strike us as being singularly unlike any thing that exists in the present world. Many species have been discovered, varying from the size of a snipe to that of a cormorant. In external form, these creatures bore a resemblance to the bat or vampire. The snout was elongated like that of the crocodile, and armed with conical teeth. The eye, as appears from the orbit, must have been of enormous size, thus fitting them, like the bat, to fly by night. They resembled the bat also in having fingers, terminating with long hooks, which projected from their wings. They were thus furnished with a powerful paw, which enabled them to creep, or climb, or hang from the trees. It is thought, also, that the pterodactyle, like some existing species of bats in the East, pos- sessed the power of swimming. As this creature had wings, it was natural to look for the structure of the bird or bat in the bones. The beak, however, had teeth, and the form of a single bone enabled Cuvier to decide that the animal belonged to the lizard tribe, so that it was a kind of flying reptile. The vertebræ of the neck, also, are to those of birds only as six or seven to from nine to twenty-three, while those of the back are in the reverse proportion; the ribs, too, like those of the lizard, are thin and thread-shaped, and thus differ from those of birds, as do the bones of the feet and toes. They are supposed to have fed on insects, and the presence of large fossil dragon-flies and other insects in the same quarries where the pterodactyles are found proves that they existed at the same period, and probably formed a portion of their food. They may also have fed upon fish, and some of the small marsupial animals, or those of the opossum kind, which then existed on the earth. The creature was evidently capable of perching on trees, or standing firmly on the ground, and, by folding its wings, could hop or walk like a bird. Dr. Buckland, alluding to the peculiarities of the pterodactyle, and the age in which it lived, says: “Thus, like Milton's fiend, qualified for all services and all elements, the creature was a fit companion for the kindred reptiles that swarmed in the seas or crawled on the shores of a turbulent planet. VOL. 1.-2 10 ILLUSTRATED NATURAL HISTORY. The fiend, O'er bog, o'er steep, through straight, rough, dense, or rare, With head, hands, wings, or feet, pursues his way, And swims, or wades, or creeps, or flies.' « With flocks of such creatures flying in the air, and shoals of no less monstrous ichthyosauri and plesiosauri swarming in the ocean, and tortoises crawling on the shores of the primeval lakes and rivers,-air, sea, and land must have been strangely tenanted in these early periods of our infant world." In speaking of this age of reptiles, the period of the iguanodon, Dr. Mantell says: “The country it inhabited must have been diversified by hill and dale, by streams and torrents, the tributaries of its mighty rivers. Arborescent ferns, palms, and yuccas constituted its groves and forests; delicate ferns and grasses, the vegetable clothing of its soil; and in its marshes, equiseta, and plants of a like nature, prevailed. It was peopled by enormous reptiles, among which the colossal iguanodon and the megalosaurus were the chief. Crocodiles and turtles, flying reptiles and birds, frequented its fens and rivers, and deposited their eggs on the banks and shoals; and its waters teemed with lizards, fishes, and mollusca. But there is no evidence that man ever set his foot upon that wondrous soil, or that any of the animals which are his contemporaries found there a habitation; on the contrary, not only is evidence of their existence altogether wanting, but, from numberless observations made in every part of the globe, there are conclusive reasons to infer that man and the existing races of animals were not created till myriads of years after the destruction of the iguanodon country,-a country which language can but feebly portray, but which the magic pencil of a Martin, by the aid of geological research, has rescued from the oblivion of the past, and placed before us in all the hues of nature, with its appalling dragon-forms, its forests of palms and tree-ferns, and the luxuriant vegetation of a tropical clime." These are some of the extinct animal wonders which geology presents to our view. There were, however, almost countless species of others, inferior in size, but often no less curious in their structure and endowments. These include whole races of quadrupeds, birds, fishes, reptiles, insects, and still lower organizations. There is hardly a single existing animal which has not its semblance in this field of fossil wonders. It would seem that for millions of ages the earth has been the theater of a succession of creations of animal forms; and so multitudinous are these, that the crust of the globe is, in great part, composed of their relics. A celebrated author says that “there is hardly an atom of its rocks and soil which has not passed through the complex and wonderful laboratory of life.” All the orders of animals, from the highest to the lowest, have contributed to swell the amount of the solid materials of the earth. It is supposed that limestone constitutes one- seventh part of the crust of the globe; and this, with the immense beds of chalk, flint, marl, gyp- sum, sandstone, lias, and jasper, are all of animal origin. They are, in fact, the bones and shells of the innumerable races which have lived on the carth in ages past, and which, for the most part, have become extinct. The subject of organic remains constitutes of itself a separate science, to which is given the name of Paleontology. The classification of extinct animals has been pursued with great zeal, and nearly 25,000 species have been identified. This is a field of wonders, calculated to enlarge our view of the boundaries of creation; but we must now take leave of it, and give attention to those animal races which constitute the living inhabitants of our globe. PRELIMINARY REMARKS ON THE CLASSIFICATION OF ANIMALS. When we consider the immense number of animals existing on the face of the earth, we are soon convinced that an attempt to obtain a knowledge of each of them individually, and without any acquaintance with their mutual relationships, would be a hopeless task. We We are, in fact, compelled to call in the aid of some system of classification, which, by bringing together those animals which most resemble each other, and characterizing them by some common point of structure, may enable us to form a general idea of the whole, and thus to remember more readily the peculiarities of each. Some such classification, rough and imperfect as it may be, is, indeed, formed by every obser- vant mind; and its terms find a place in ordinary language. Beasts, birds, and fishes, reptiles, INTRODUCTION. 11 PARALLELISMS BETWEEN QUADRUPEDS AND BIRDS. 12 ILLUSTRATED NATURAL HISTORY. and insects, are words familiar to every one, and convey to the minds of those to whom they are addressed a more or less definite idea, according to the preconceived notions of the hearer. Ingenious authors have, at different times, suggested systems of classification, based upon less obvious analogies. Linnæus, for instance, long since remarked a curious parallel between certain classes of quadrupeds and birds, as well in their structure as their habits and destination in the great economy of animal life. A late writer of distinction, M. Le Maout, in his “Histoire Naturelle des Oiseaux," has exemplified this in an engraving, which we here insert. On the left hand, in the top of a palm-tree, is seen a monkey, and opposite, in a similar situation, is a parrot. These are severally at the summit of their orders, by reason of their cerebral development. They also approach each other by their capacity for climbing and their habit of living on fruit; both use their limbs for carrying food to their mouth ; both are endowed with the instinct of imitation—the one simulating the gestures of mankind, and the other the human voice. The next types, seen in the top of the engraving, are flesh-eaters—the leopard and the eagle; both subsisting upon living prey; both gifted with the keenest faculties for pursuing and seizing it; both supplied with means to rend and devour it; both remarkable for their ferocity and their rapid and powerful muscular action. Both are seen pursuing the same game—the antelope of the wilderness. The next types are still flesh-eaters, but of an inferior order, and living upon carrion. One con- sists of hyenas, the other of vultures; both cowardly, but voracious, and finding a relish in putre- faction; both live in the vicinity of man, and serve as scavengers to remove animal matter, that, in its decomposition, might beget pestilence; both are grouped in the engraving as feasting together on the same carcase. The next group consists of a tupaia-an animal resembling the squirrel—and a starling; both feeding on insects, and living mostly upon the trees. The next consists of the field-mouse and the sparrow, feeding upon seeds. The next presents a herd of antelopes—ruminants of complex stom- achs, feeding on mountain pasturage, with the gallinaceous nepaul, the two horns of which form a close analogy to these animals. Next comes the dromedary, a ruminant without horns, and living upon herbs in the desert; and the ostrich, with its capacious crop, also herbivorous, and making the desert its home. Finally, we have the seal and the penguin, both possessing abortive limbs, and both plunging under the water for their food. These analogies are curious and striking, but they are not so obvious and useful, for the basis of scientific arrangement, as the more common grouping to which we have alluded—that of beasts, birds, fishes, and reptiles. The received zoological classification is, in point of fact, to a certain extent, coincident with this popular classification. The latter being the result of observation, the only foundation of natural history, must necessarily be more or less correct, according to the extent to which the different kinds of animals are brought under the notice of mankind; thus we find that tolerably clear notions exist as to the differences between a beast, a bird, and a fish, — these being creatures that pass constantly before our eyes; although, even with respect to these groups, we find some erroneous ideas to prevail. But with respect to insects, and other lower animals with which mankind at large are not familiar, the classification of ordinary language is by no means so precise ; so that while, in the former cases, zoology can adopt the popular groups merely by submitting them to a few modifi- cations, in the latter, science is compelled to invent a system of its own. This scientific classification is not, however, a mere arbitrary arrangement like that of the words in a dictionary, with the sole object of enabling us to find out all that is known of a given animal in the shortest possible period of time: it has another and a higher purpose in view—that of showing the mutual relations of the various members of the animal kingdom, and tracing, in a manner, the steps taken by the Creator in the modification of the same type to suit the various conditions in which His creatures were to be placed. a OF CERTAIN TERMS USED IN NATURAL HISTORY. A clear idea of the terms species, variety, genus, family, tribe, order, class, and division, which are constantly occurring in treatises on natural history, is essential to an understanding of the subject. INTRODUCTION. 13 . Species is applied to the several animals of one kind; thus all the ducks, of one kind, constitute the species. This classification is founded upon similarity of color, size, proportion, form, &c. Variety is a term applied to animals which vary in some of their qualities from the general character of their kindred, while they are, in fact, of the same nature and structure. Genus is founded upon some of the less important characteristics of anatomy, such as the number and arrangement of the teeth, claws, fins, &c., and usually includes several species. Thus the lion, tiger, jaguar, puma, cat, &c., resemble each other in the qualities of their feet, teeth, and limbs, and therefore constitute a genus called felis. The term family is used to designate a group of several genera which have a resemblance to each other. Thus, the sprat, shad, herring, pilchard, and alewives, each forming a genus, con- stitute the family Clupeide. The jays, jackdaws, crows, and ravens constitute the family Corvidæ. Several of these families combined form an order, and several orders constitute a class, and classes form divisions. Another word of great use in natural history is type, which means the general idea of some animal which combines most fully the characteristics of the group to which it belongs. Thus the falcon may be selected as the type of the hawks, generally; the duck may be taken as the type of the diving birds, generally; and the mallard the type of the duck species. The knowledge of species constitutes the foundation of all zoological knowledge; without this, we can never arrive at sound generalizations. The species, which forms the first step in classifi- cation, consists of an assemblage of individual animals which are supposed all to have descended from the same parents, and exhibit the closest possible resemblance in all parts of their structure. This definition, if definition it may be called, must not, however, be taken in the strictest sense which might be applied to the words; for in many cases we find that individuals undoubtedly belonging to the same species vary considerably among themselves, principally in color and size. Variation is generally to be observed, however, in animals under the influence of domestication; the individuals of most species of wild animals resembling each other so closely that it would be difficult to overlook their specific identity. A test for the specific identity of animals, upon which much stress has been laid, is founded upon the supposed fact, that when two animals of different species breed together, their offspring, called hybrids, are barren. This test is evidently applicable only when we can have the animals alive, subject to our notice; while, even under the most favorable circumstances, such observations would be very inconclusive, as hybrids between undoubtedly distinct species have been frequently known to breed. MODERN SYSTEMS OF CLASSIFICATION. The arrangement of the species of animals in genera, gives rise to the modern system of zoo- logical nomenclature. This is called the binomial system, from the circumstance that, according to this method, every animal receives two names,-one belonging to itself exclusively, the other in common with all the other species of the genus in which it is included. For example, the genus Felis, or cat, includes the lion, tiger, leopard, and cat, as species ; they all accordingly bear the generic name Felis, with the addition of a second name specially applied to each, serving to distinguish it from all other species of the genus : thus the lion is called Felis leo, the tiger Felis tigris, the leopard Felis leopardus, and the cat Felis catus. This method of nomenclature has at least this advantage over the plan of conferring only a single name upon each species—that when we hear for the first time the name of a newly discovered animal, if we are at all acquainted with the genus to which it belongs, the mere mention of the name puts us at once in possession of a considerable amount of information as to its structure, form, and habits. It was first adopted by the illustrious Linnæus, the modern founder of Natural History, in the tenth edition of his Systema Naturæ," published in 1758. Proceeding with our ascending scale of classification, as indicated above, we find that the genera in their turn are sometimes united by common characters of importance into families, and these combine to form orders. In some cases we meet with intervening steps, uniting the tribes belonging to one order into two or three subordinate groups. The orders in their turn group themselves 14 ILLUSTRATED NATURAL HISTORY. into classes ; and these lead us up to certain primary divisions, which, when put together, con- stitute the ANIMAL KINGDOM. The classification of Linnæus was an immense improvement upon all that had gone before, and though it is now in a great measure superseded, it is still partially retained and often referred to in modern systems : it may therefore be useful to present it to the reader. It was as follows: LINNÆAN SYSTEM. According to this system, the objects comprehended within the animal kingdom are divided into six classes : Mammalia or Mammiferous Animals, Birds, Amphibia or Amphibious Animals, Fishes, Insects, and Worms, which are thus distinguished : CLASSES. Hot blood With vertebræ.. Body Cold red blood.... Viviparons 1 Oviparous. With lungs. With gills Having antenna Having tentacula. I. MAMMALIA II. BIRDS. III. AMPHIBIA. IV. FISTIES. V. INSECTS. VI. WORMS. Without vertebræ Cold white blood.. a Class. I.-MAMMALIA. The first class, or Mammalia, consists of such animals as produce living offspring, and nourish their young ones with milk supplied from their own bodies; and it comprises both the quadrupeds and the cetacea. This class is divided into seven orders, viz. : primates, bruta, feræ, glires, pecora, belluæ, and cetacea or whales. The characteristics of these were founded, for the most part, on the number and arrangement of the teeth ; and on the form and construction of the feet, or of those parts in the seals, manati, and cetacea, which supply the place of feet. I. PRIMATES. -Having the upper front teeth, generally four in number, wedge-shaped and parallel ; and two teats situated on the breast, as the apes and monkeys. II. BRUTA.—Having no front teeth in either jaw ; and the feet armed with strong hoof-like nails, as the elephant. III. FERÆ.--Having in general six front teeth in each jaw; a single canine tooth on each side in both jaws; and the grinders with conic projections, as the dogs and cats. IV. GLIRES.—Having in each jaw two long projecting front teeth, which stand close together; and no canine teeth in either jaw, as the rats and mice. V. PECORA. --Having no front teeth in the upper jaw ; six or eight in the lower jaw, situated at a considerable distance from the grinders ; and the feet with hoofs, as cattle and sheep. VI. BELLUÆ.—Having blunt wedge-shaped front teeth in both jaws; and the feet with hoofs, as horses. VII. CETACEA.-Having spiracles, or breathing-holes on the head ; fins instead of fore-feet; and a tail flat- tened horizontally, instead of hind-feet. This order consists of the narwhals, whales, cachalots, and dolphins. Class II.-BIRDS. The second class, or Birds, comprises all such animals as have their bodies clad with feathers. This part of zoology, being called Ornithology, is divided into six orders. 1. Land Birds. I. RAPACIOUS BIRDS (Accipitres).-Having the upper mandible hooked, and an angular projection on each side near the point, as the eagles, hawks, and owls. II. PIES (Picæ).-Having their bills sharp at the edge, somewhat compressed at the sides, and convex on the top, as the crow. III. PASSERINE BIRDS (Passeres). --Having the bill conical and pointed, and the nostrils oval, open, and naked, as the sparrow and linnet. IV. GALLINACEOUS BIRDS (Gallinæ. -Having the upper mandible arched, and covering the lower one at the edge, and the nostrils arched over with a cartilaginous membrane, as the common poultry. 2. Water Birds. V. WADERS (Grallæ).-Having a roundish bill, a fleshy tongue, and the legs naked above the knees, as the herons, plovers, and snipes. VI. SWIMMERS (Anseres). --Having their bills broad at the top, and covered with a soft skin, and the feet webbed, as ducks and geese. CLASS III.-AMPHIBIA. The third class, or Amphibia, included such animals as have a cold, and generally naked body, a lurid color, and nauseous smell. They respire chiefly by lungs, but they have the power of suspending respiration for a INTRODUCTION. 15 long time. They are extremely tenacious of life, and can repair certain parts of their bodies which have been lost. They are also able to endure hunger, sometimes even for months, without injury. This class was divided into two orders. I. REPTILES. --Having four legs, and walking with a crawling pace, as the tortoises, toads, and lizards. II. SERPENTS. -Having no legs, but crawling on the body. Class IV.-FISHES. This class included inhabitants of the water, which move by certain organs called fins. Those situated on the back are called dorsal fins; those on the sides, behind the gills, pectoral fins; those below the body, near the head, are ventral; those behind the vent are anal ; and that which forms the tail is called the caudal fin. The fishes were divided into six orders. I. A PODAL.-Having bony gills; and no ventral fins, as the eel. II. JUGULAR. —Having bony gills ; and the ventral fins situated in front of the pectoral fins, as the cod, had- dock, and whiting. III. THORACIC.—Having bony gills; and the ventral fins situated directly under the pectoral fins, as the perch and mackerel. IV. ABDOMINAL. Having bony gills ; and the ventral fins on the lower part of the body below the pectoral fins, as the salmon, herring, and carp. V. BRANCHIOSTEGOUS. -Having gills destitute of bony rays. VI. CHONDROPTERYGEOUS.-Having cartilaginous fins, as the sturgeons, sharks, and skate. Class V.-INSECTS. This class comprised the Insects; and the branch of zoology which treats of them is called Entomology. It was divided into seven orders. I. COLEOPTEROUS.-Having elytra, or crustaceous cases covering the wings; and which, when closed, form a longitudinal division along the middle of the back, as the cockchafer. II. HEMIPTEROUS.-Having four wings, the upper ones partly crustaceous and partly membraneous; not di- vided straight down the middle of the back, but crossed, or incumbent on each other, as the cock- roach. III. LEPIDOPTEROUS.—Having four wings covered with fine scales almost like powder, as the butterflies and moths. IV. NEUROPTEROUS.—Having four membraneous and semi-transparent wings, veined like net-work; and the tail without a sting, as the dragon-fly and ephemera. V. HYMENOPTEROUS.—Having four membraneous and semi-transparent wings, veined like net-work; and the tail armed with a sting, as the wasp and bee. VI. DIPTEROUS.—Having only two wings, as the common house-flies. VII. APTEROUS. -Having no wings, as the spiders. Class VI.–VERMES, OR WORMS. These are slow of motion, and have soft and fleshy bodies. Some of them have hard internal parts, and others have crustaceous coverings. I. INTESTINAL.- Are simple and naked, without limbs : some of them live within other animals, as the ascarides and tape-worms; others in water, as the leeches ; and a few in the earth, as the earth- worm. II. MOLLUSCOUS. ---Are simple animals, without shells, and furnished with limbs, as the cuttle-fish, medusæ, star-fish, and sea-urchin. III. TESTACEOUS. —Are animals similar to the last, but covered with shells, as oysters, cockles, snails, and limpets. IV. ZOOPHYTES.- Are composite animals, and appear to hold a rank between animals and vegetables; though a they are in fact true animals, and possess sensation and voluntary motion. In many instances a great number of them inhabit the same stone, but some are soft, naked, and separate. The coral, sponge, and polypes are instances of this order. V. ANIMALCULES.- Are destitute of tentacula or feelers, and are generally so minute as to be invisible to the naked eye. They are chiefly found in different infusions of animal and vegetable substances. This classification continued to be the leading one among scientific men, till the publication of the Animal Kingdom of George Cuvier, in 1816. This admirable work, being founded upon a profound study of the structure of animals by means of dissection, was generally adopted; and ; though portions of it have been modified by the researches of eminent naturalists in particular branches of zoological science, and hence new systems of classification have been proposed and adopted, it still remains as the basis of all those which have acquired reputation with the learned world. This classification is as follows: 16 ILLUSTRATED NATURAL HISTORY. THE ANIMAL KINGDOM ARRANGED ACCORDING TO THE SYSTEM OF CUVIER. CLASS I. MAMMALIA, including Eight Orders. CLASS II.

ANALYSIS OF THE SYSTEM OF CLASSIFICATION ADOPTED IN THIS WORK. a a In this volume we shall adopt a system of classification suited to the present improved state of zoological science. It may be well to indicate, at this point, the mode of analysis by which this arrangement is reached. But it is necessary first to state that modern investigations, aided by the wonderful powers of the microscope, have enabled scientific men to analyze the various substances of which the bodies of animals are composed, and to reduce them into their elements. Numerous and varied as are these substances—bone, cartilage, sinew, nerve, muscle, hair, teeth, nails, claws, even the trans- parent lens of the eye—all are reducible to one kind of structure, and this is a cell. All organic substances are made up of cells. The primary organic cell is a minute pellucid globule, invisible to the naked eye, and containing within it a smaller cell, called the nucleus, which again contains a still more minute granule, called the nucledus, or little nucleus. Even the highest animals, in the early development of the embryo, are composed entirely of nucleated cells, which afterward assume the forms peculiar to the various tissues of which their bodies are composed. At the lowest point of the animal kingdom, verging so closely on the lowest forms of plants to leave us at first in doubt to which of the great divisions of organized nature they should be referred, we meet with a series of creatures in which the functions of organic life are performed by its simplest element—the cell. From this circumstance they have received from naturalists the denomination of unicellular animals, or PROTOZOA. These animals, though presented to us in a variety of forms, from the simple monad up to the complicated sponges, consist entirely of elementary nucleated cells, or of aggregations of such cells, in which each still retains, to a certain extent, an existence independent of its fellows, and generally possesses the power, when separated from its attachments, not only of continuing its own life, but even of producing another compound structure similar to that from which it had been detached. These simple creatures possess no digestive cavity, their food, when solid, being received into the substance of the body, and there gradually assimilated. The nervous and vas- cular systems are equally deficient; in fact, the nucleus, which is an essential portion of the elementary cell, and one or more contractile vesicular spaces, are the only traces of internal organ- ization observable in the clear gelatinous substance of which they are composed. Reproduction is effected in general by the division of the substance of the animal: the phenom- ena of sexuality, which we shall meet with in all the higher animals, are here never witnessed. From these simple creatures we pass to a group of animals, the lowest members of which exhibit but little, if any, advance in point of organization. They do not, it is true, consist of isolated cells, Vol. I.--3 18 ILLUSTRATED NATURAL HISTORY, ru WAN Bles www wwwNN Wiki STAR-FISH: DIVISION RADIATA. or of aggregations of similar independent cells; but in many instances their bodies and organs are constructed entirely of a gelatinous cellular matter very like that of which the Protozoa are com- posed, and which appears to possess almost an equal power of retaining vitality in its smallest particles. As we advance in the group, however, we find the organization of its constituent ani- mals growing more and more complicated, from the vital functions becoming more and more differentiated—that is to say, performed by organs specially devoted to each; until, from creatures roughly shaped out of a homogeneous semi-gelatinous mass, we gradually arrive at animals fur- nished with distinct nervous and vascular systems, with organs of motion and reproduction. , The most striking character of the animals included in this group consists in the radiate arrange- ment of their organs, as in the star-fish, round a central axis, which generally passes through the mouth. From this peculiarity they have been denominated by zoologists radiated animals, and constitute the division RADIATA. This group includes those animals which were formerly supposed to approach very closely to plants, or indeed rather to partake of a sort of mixed nature interme- diate between animals and vegetables, hence called zoophites, or animal-plants ; and some authors still make use of this name in preference to that of Radiata, to indicate the present group. The nervous system can only be recognized distinctly in the most highly organized of these animals. In these it partakes of the radiate arrangement of the body, the nerve distributed to each division of the body corresponding exactly with those of its neighbor, and arising from a separate center. These centers are all placed in a circle round the mouth, and united by a cord which forms a complete ring. The sense of touch appears to be the only one which can with certainty be ascribed to these animals; this resides in the general covering or integument, and is also frequently exercised by special organs. All the Radiata possess a mouth and intestinal cavity; but very few of them have a second opening for the discharge of fecal matters. They generally possess a more or less distinct vascular system: in some of the higher forms a sac-like heart occurs. Sexual reproduction occurs in all the Radiata, and the sexes are generally on separate individ- nals. Propagation is also very commonly effected in this division by the formation of buds or gemmules; and these either remain attached to the parent stock, which thus goes on increasing continually in size, or become free, and lead an independent existence. In the two preceding divisions of the animal kingdom we find the body formed upon two very INTRODUCTION. 19 SCORPION AND CENTIPEDE: DIVISION ARTICULATA. different principles. In the first and lowest, it may almost be said to be amorphous. The organs, such as they are, follow no particular arrangement; and in many cases it is impossible even to fix their relative position. In the second, however, a certain symmetry is observable; and this is the case also with the remaining groups, the characters of which we have yet to lay before the reader. But this symmetry is of a very different kind : in the Radiata, the parts of the body are all grouped around a common axis, every organ being merely a repetition of its fellows; while in those which must now pass under consideration, the organs of the body are arranged more or less distinctly in pairs on each side of the body, so as to produce what has been termed by zoolo- gists a bilateral symmetry. In none do we find this mode of construction so completely exhibited as in the animals forming the third primary division of the animal kingdom, to which we must now direct attention. The most striking peculiarity of these animals, by which—although the division contains an almost infinite variety-insects of all kinds, crabs, lobsters, centipedes, &c.—they may generally be distinguished at the first glance from all other creatures, is, that their bodies and limbs are composed more or less distinctly of segments or rings. From this, which is their most prominent character, they have been denominated articulated animals. They are also sometimes called annulose or ringed animals. These constitute the division ARTICULATA. The joints or segments of which their bodies are composed are formed essentially by a series of transverse folds in the integument of the animal. In many of the lower forms, the skin still remains perfectly soft and flexible ; but in by far the greater number these folds become trans- formed into a series of horny or crustaceous rings, united to each other by a softer portion of the integument, so as to permit a greater or less degree of flexibility. The limbs, as well as the body, are constructed of rings of various forms; and these, taken together, may be regarded, to a certain extent, as a sort of external skeleton, fulfilling, as they do, most of the purposes of the skeleton in man and the animals most related to him. Like this, it gives support to all the soft parts of the body, and furnishes points of attachment for the muscles; which again, by their action on the , movable pieces composing it, give rise to the various movements of the creature. In many cases, all the segments composing the body, with the exception, perhaps, of those at the two extremities, are exactly similar,—each presenting the same form and bearing the same organs as its neighbor. An instance of this may be seen in the centipede, figured above ; and it is still more strikingly exemplified in many marine worms. Generally, however, the segments present marked differences of form and comparative size, and in the structure of their appendages : this is very distinctly observable in the insects and crabs. 20 ILLUSTRATED NATURAL HISTORY. CRABS : DIVISION ARTICULATA. Every segment is supposed to be capable of bearing two pairs of appendages or members-one connected with the central, the other with the dorsal, portion of the segment. Both pairs of members do in fact occur upon all or a portion of the segments, in some of these animals; but in general, the ventral members alone are developed, and these only on certain segments. In the insects, in addition to three pairs of ventral members or legs, we find generally two pairs of dorsal appendages—the wings. Sometimes, as in the earthworm and leech, the limbs are entirely defi- cient, or only represented by a few bristles; but, when present, their number is never less than six. The nervous system of the Articulata generally exhibits the tendency to segmentary repetition, characteristic of the group, very distinctly. In its most characteristic form, it consists of a double nervous cord running down the middle of the ventral portion of the body, and uniting a series of knots or ganglia which lie in its course : these ganglia give rise to nerves which are distributed to the various organs. The more elongated the body, and the more similar the different seg- ments of which it is composed, the more regularly do the ganglia follow one another; while, when the segments become more or less amalgamated, the individual ganglia fuse in a correspond- ing degree into larger masses. This ventral cord originates from one or more cephalic ganglia of considerable size, situated in the head above the esophagus, which give off two filaments to join the first ventral ganglion, and thus form a nervous ring surrounding the æsophagus. From this the ventral cord takes its rise. In the lowest animals arranged in this division we have some difficulty in referring the nervous system to the articulate type; but when these animals present us with a distinct nervous system, it consists of one or two ganglia situated in the neighborhood of the æsophagus, and giving off two thin branches which run down the body. The majority of the Articulata possess the senses in tolerable perfection. The eyes in many cases present a highly complex structure, consisting of a great number of hexagonal facets, each of which may be regarded as a distinct eye; this construction of the eyes is especially prevalent in insects, and is peculiar to the annulose division. When these eyes are wanting, and even when they are present, we frequently meet with simple eyes, which agree very closely in structure with the individual eyes, by the aggregation of which the compound visual organs are formed. The senses of hearing, taste, and smell appear also to be possessed by a great many of these creatures; but the organs by which these faculties are exercised can seldom be indicated with any degree of INTRODUCTION. 21 SPIDERS: DIVISION ARTICOLATA. certainty. The sense of touch of course resides in the general integument; but special organs of touch are also frequently developed. The mouth is nearly always furnished with several pairs of jaws, placed one behind the other, some serving for the prehension and others for the mastication of food. These jaws open later- ally, so that the aperture of the mouth is vertical, or in the direction of the axis of the body. Most of the Articulata have whitish or colorless blood. The only exceptions are to be met with among the worms, some of which have red blood. In these, however, the color of the blood is inherent in the fluid portion, and not due to the presence of red corpuscles. Their circulation is effected by means of a dorsal vessel, which carries the blood from behind forward : it returns to the posterior portion of the body, either through a proper vascular system, or by passing through interstices left in the tissues of the body. Sexual oviparous reproduction prevails throughout this division. The sexes are generally sep- arate, although in some of the lower forms we meet with complete hermaphrodism. In the fourth great division of animals, the bilateral type of structure is far from being so distinct as in the Articulata. It is stiil, however, to be recognized in the general arrangement of the external organs, especially of those surrounding the head. Those animals of which the snail, clam, oyster, and nautilus may be taken as familiar examples, are usually inclosed in a tough skin, to the inner surface of which the muscles are attached, and by its contraction and dilatation the movements of the animal are effected. With the exception of the cuttle-fishes, in which a sort of cartilaginous support is present, none of these creatures possess any thing which can be regarded as analogous to a skeleton; the body forms a soft mass, frequently varying greatly in form at the will of the creature. These peculiarities have led zoolo- gists to give them the name of molluscous or soft-bodied animals: they constitute the division MOLLUSCA. In most of these animals the nervous system consists of a number of knots or ganglia, scattered more or less irregularly through the body, united with each other by nervous filaments, and giving off finer filaments, the true nerves, to the various organs. In the more highly organized Mollusca, three or four of these ganglia are collected in the head, forming a cephalic mass, which represents a brain; but even in its most condensed form, the cephalic ganglia may still be recognized, form- ing a sort of ring through which the æsophagus passes. 22 ILLUSTRATED NATURAL HISTORY. 0 € LOG 100 SEGEL CUTTLE-FISH: DIVISION MOLLUSCA. Some of the lower forms, arranged with the molluscous animals by modern zoologists, possess only a single ganglion, from which filaments are given off in all directions; and between this and the highly complicated structure, we meet with every conceivable gradation. As might be expected from the great differences displayed by the members of this division of the animal kingdom, in regard to the degree of development of the nervous system, the senses are possessed by them in very various degrees of perfection. In some of the lowest forms the universal sense of touch appears to be the only one present; but as we ascend in the scale, we meet with creatures more highly endowed in this respect. Tentacles, or special organs of touch, , frequently occur, generally in the neighborhood of the head; organs of sight, hearing, smell, and taste make their appearance, until in the highest forms of molluscous animals we find the organs of the senses as fully developed as in many of those belonging to the highest division. The skin of these animals generally lies loosely about the body, so as to form a sort of cloak or mantle. The mantle frequently possesses the power of secreting a hard substance, well known as the shell, which serves for the protection of the creature. It increases with the growth of the ani- mal, and varies in form according to the species which inhabits it. The intestinal canal is very variable in its structure, but always presents two openings—a mouth and an anus; the liver frequently attains a very great degree of development. The circulatory system is generally very highly organized; a heart, often divided into several compartments, with arteries and veins penetrating all parts of the body, existing in nearly all the Mollusca. The blood is colorless, or nearly so. The Mollusca are oviparous animals; the male and female organs are frequently in separate in- dividuals, although many species are hermaphrodite. In the fifth and highest division of the animal kingdom, we meet with a series of organs to which nothing similar occurs in the groups which have already passed under review. All these animals possess a nervous system, consisting essentially of a brain, inclosed within a bony case, the skull, beneath which the wesophagus passes, and a single cord of nervous matter, a INTRODUCTION. 23 power NAUTILUS WITH THE SHELL : DIVISION MOLLUSCA. originating from the lower part of the brain, passing through a large hole in the base of the skull and running down through a bony canal, formed by the vertebral column, of which the skull is, in fact, only the anterior portion. As this set of organs—the brain and the spinal cord, the skull and the vertebral column-while possessed by no other animals, is, with a few rare exceptions, con- stantly present in these, its existence will always serve to distinguish them from the rest of the animal kingdom. They are accordingly called vertebrate animals, and the division which they form, VERTEBRATA. These, however, are not the only characters possessed in common by vertebrate animals. The vertebral column forms only a portion of an internal bony framework or skeleton, which serves for the support of the soft portions of the body, and by furnishing the necessary points of attach- ment for the muscles, assists in effecting the movements of the animal. This framework generally consists of the vertebral column, including the skull; the jaws, which are regarded as appendages of the vertebræ, of which the skull is considered to be composed; the ribs, a series of bony arches, articulated at one extremity with the bones of the vertebral column, and at the other either at- tached to a central bony piece, the sternum, or lying perfectly free in the tissues of the body; and the limbs, which are never more than four in number. The jaws in these animals always separate in a vertical direction, so that the opening of the mouth is transverse. They all have red blood and a muscular heart. Their reproduction is sexual, and the sexes are never united in the same individual. The animals constructed upon this type are the most highly organized of living beings. In no others is the nervous matter, the seat of sensation, intelligence, and volition, presented in so con- centrated a form ; in none are the senses so perfect, or the various functions of the animal econo- my so completely isolated. We thus see that animals are constructed upon Five Primary Types or Plans, of which all the varied forms presented by these creatures are but modifications; as though the Creator, in design- a 24 ILLUSTRATED NATURAL HISTORY. مجيد به 1560 NAUTILUS WITHOUT THE SHELL : DIVISION MOLLUSCA. ing the animal world, had imposed upon himself, in the beginning, certain fixed rules, from which he would not swerve. In this manner we obtain Five Groups or Divisions, each of which leads us a step higher than the others—although it is by no means to be supposed that we have here that gradually ascend- ing chain of beings so much talked of, in which every species, from the lowest to the highest, is supposed to form a link. It is merely in their most highly organized members that the mutual superiority or inferiority of these divisions can be recognized; and, as a general rule, it may be said, at all events in respect to the Radiata, Articulata, and Mollusca, that the highest members of each group are considerably more perfectly organized than the lower members of the others. The Pro- tozoa and Vertebrata appear to be exceptions to this rule; for the most highly organized of the former can scarcely be regarded as superior even to the lowest forms of the other divisions, while the fishes, which constitute the lowest members of the vertebrate division, still appear to be more highly organized than the lowest Mollusca. These five divisions are represented in the following classification, though they are presented in a reversed order, it being more according to our habits of observation to begin the study of the animal kingdom with the highest classes, and thence to proceed to those of a lower grade, as they follow in the places assigned to them. In regard to this classification, we may remark that, simplicity being a leading object, we have only presented the divisions of Species, Genera, Orders, Classes, and Divisions, leaving out many subdivisions of tribes, families, &c., as unnecessary in a table of this naiure. In the progress of the work we shall have occasion to repeat, and in some instances to enlarge upon, the outline given in the preceding pages.

The one here adopted serves all practical purposes, and rests on good authorities. Other ways of classifying some of the groups are shown in the Appendix.–See this volume for Mammals, and the second volume for the other groups. OF SPECIES BELONGING TO THE ANIMAL KINGDOM. The preceding Classification embraces the entire animal kingdom, exclusive of fossil remains. The number of species belonging to this has been estimated as follows: Mammalia, 2,000; Birds, 6,000; Reptiles, 2,000; Fishes, 10,000; Mollusca, 15,000; Articulata, 200,000; Radiata, 10,000: making 245,000 in all. It is supposed the fossil species may be equal in number to these, making nearly half a million. It is highly probable the actual number of species in the animal kingdom is even beyond this. All these, however, are not yet actually known. About a century ago, the whole number of as- certained species did not exceed 8,000; but such have been the earnestness and activity of re- search, that 60,000 species have now been made out and described. Specimens of about 1,500 mammalia, 5,000 birds, 1,500 reptiles, 6,000 fishes, 10,000 mollusca, and 50,000 insects and other articulata are in the various collections and museums of Europe. a * It is proper to state that in preparing this Classification, and in various parts of the preceding Introduction, we have been largely indebted to the excellent Natural History of W. S. Dallas, London, 1856.
