IN presenting this version of the “Animal Kingdom” of the celebrated Cuvier to the British public, the Translator feels assured that he has only acted in compliance with the wishes of the most intelligent portion of the community, inasmuch as the great deficiency in our language of a complete work in this grand department of Natural History is thus supplied in a manner that it is impossible to excel. It is essential for the reader to understand that the attempts hitherto made by English authors to enrich British scientific literature with the labours of Cuvier, have been confined to the translation of the first edition of the “ Regne Animal,” which made its appearance so far back as the year 1816. With respect to that translation, it is not necessary that we should dwell upon it farther than to observe, that it is the version of a work which may now be deemed to be completely superseded. The great French author himself, indeed, has acknowledged the imperfections of his first edition, as compared with the last, which is now enriched with the results of labours, whereby, during the interval of twelve years, an immense pro- gress is declared by Cuvier to have been effected in this science. It is scarcely necessary to add, that no part of those labours, and no por- tion of that improvement, failed to be examined by this indefatigable naturalist. His connection with the government of France, his reputa- tion throughout Europe, and his consequent unbounded facilities of com- munication with fellow-labourers in all quarters of the globe, gave to Cuvier opportunities of procuring information of new facts, or corrections of former errors, such as could not be accessible to almost any other individual. From considering these facts, the reader will not fail to conclude that a difference, to no small amount, must necessarily exist between the former and the latter edition of the “ Animal Kingdom;” nor will he, upon due examination, be prepared to deny that the latter is essentially a new and distinct work, from the number of alterations and improvements which have been incorporated with it. Cuvier records, with the most grateful expressions, his sense of the value of the information derived by him from the vast number of faithfully executed figures in Natural History which were supplied by recent travellers. The difficulties presented in the arrangement of the synonymes in the nomenclature of animals were also found by our great author very seriously diminished when he came to prepare the second edition of his “ Regne Animal.” Naturalists of 11 ADVERTISEMENT. all countries felt the necessity of more minute distinctions being esta- blished amongst those extensive groups which they had previously formed, and the result was a much nearer approximation than ever to an exact definition of each of the species. We refer to the Preface, at page xxx of the present volume, for a more copious account of the advantages which the last edition of the “ Animal Kingdom” presents, as compared with the first. It remains for us, then, merely to state, that we felt the great importance of at once adding to our scientific literature a work of such permanent value as the “ Animal Kingdom” of Cuvier. The character of the author for a profound knowledge of his subject — the conviction which we entertained of his exact accuracy in all that related to his labours, seemed to be sufficient to authorize us in trusting altogether to his authority ; and if we have added a few notes occasionally in the present volume, our object only was to enable our readers to make such an application of the text as our local advantages in this country enabled us to do. In the following work, therefore, the reader will not find himself di- verted from the regular current of the simple text by any protracted and tedious notes, which dispute, as it were, the right to the space of every page with the actual contents of the original. We have, in the front of our announcement to the public, pledged ourselves to place the British reader on a level with the French one, in comprehending the result of Cuvier’s researches into the most interesting of the subjects that can engage the mind of man ; and to the fulfilment of that pledge we feel it to be our duty to adhere. Fidelity, then, in the translation, was the first grand object of our care. We have laid it down as a fixed rule, never to depart, even in a casual expression, from a most faithful representation of the thoughts and words of the original ; and we trust that we have not failed altogether in our attempt to transfer from his pages some portion at least of the energetic spirit, yet true simplicity, by which Cuvier’s style is so happily distinguished. It has been, therefore, no object of our ambition, on this occasion, to attempt the improvement of the charming colours of the lily, or give fresh beauty to the glowing hues of the violet. Our task was plain ; and we felt that we performed enough, in devoting the whole of our exertions to effect the nearest possible approximation to the style and manner of the great Original — in other words, to secure to the English nation all the advantages of such an easy and instructive exposition of scientific knowledge as the French nation had already at their command. MEMOIR OF BARON CUVIER. ALTHOUGH France is entitled to all the glory which is reflected upon her by the fame of the illustrious Cuvier, yet he was only her child by adoption, if we are to consider the claims of locality as capable of deciding the point of affinity between country and individuals. He was born on the 23d of August, 1769, at Montbeillard, which was, at the period of his birth, and for several years afterwards, included in the duchy of Wirtemberg. Here it was that his father had ultimately chosen his re- sidence, after having devoted the best years of his life to the military service. The elder Cuvier was a Swiss, who had in early life entered the French army, and, having faithfully adhered to the government of France, he, at the conclusion of his active labours, retired to his native town of Montbeillard, on a small pension, which eventually was considerably in- creased by the revenue accruing from a fresh appointment as com- mandant of the artillery. In his childhood, the subject of our memoir exhibited all the charac- teristic marks of a feeble constitution. The cares of his mother were for this reason redoubled; and her affectionate vigilance was rewarded in the unceasing veneration of the surviving object of it to the latest moment of his existence. It was to her that he was indebted for his early devotion to books and the art of drawing. He was successively placed in the in- stitutions for education in its various branches, which had, even at that early period, been common in the country ; and, it is a curious fact, that his first impressions of partiality for natural history were derived from the sight of a Gesner with coloured plates, and also from the perusal of those accompanying the work of Buffon, of which a copy was by accident accessible to him. The sort of talent displayed by young Cuvier whilst still occupied in the rudimentary schools of Montbeillard, was of a nature to point him out as a fit candidate for the church ; and, as he was educated in the Protestant religion, the local government, which was Pro^- testant also, took the usual measures for securing the services of such a promising auxiliary in maintaining a religion surrounded by an opposition of the most formidable nature. In furtherance of these views, Cuvier was sent to Studtgard, and was placed, by order of Prince Charles of Wirtemberg, in the college called VOL. i. 6 11 MEMOIR. the Academie Caroline, an institution belonging to the university of that city. After having spent some time in the various studies which were en- joined on pupils of his age, Cuvier appears to have been closely attended to by the Duke, and, as there is reason to believe that the latter acknow- ledged some serious obligations in former times to members of the Cuvier family, so did he feel a peculiar interest in forwarding the views of the young aspirant. It appears, that though the youth was at first intended for the clerical profession, yet at Studtgard his studies were all directed to his education for performing political duties. We can readily believe that the courses thus enjoined upon him were sufficiently agreeable to his tastes, when we remember that they comprehended the branches of natural history. He seems to have had leisure enough to perform herborizing ex- cursions, to visit collections of objects in art and nature, and even to copy the representations of animals. At Studtgard he distinguished himself by obtaining many of the prizes, and succeeded in attaining the order of chi- valry, a sort of distinction which fell to a very small number of the pupils who won it by their merit. The accident of the retirement of Duke Frederick, the governor of Montbeillard, into Germany, deprived young Cuvier of his most powerful friend, and, for a moment, he suspended those ambitious hopes which had long floated before him. Without patrimony, or the means of entering upon any permanent system for his life, Cuvier was under the necessity of seeking out a tutorship. In 1788, we find him in the family of Count d’Hericy, at Caen, in Normandy, where he was engaged in the instruc- tion of an only son. The proximity of this Norman residence to the sea afforded to the active tutor facilities for such observations on natural pro- ductions as his instinctive inclinations led him to seek ; and it was to the accidental opportunities thus presented to him, that he owed the impulse, which, in its subsequent influence, so vastly contributed to build up his great reputation. Cuvier, being destitute of books or other means of re- ference at the period we are speaking of, committed the results of his disco- veries to paper, and the manuscripts survived to be of essential service to him afterwards. At this interesting era of the life of Cuvier, a circum- stance occurred which must not be omitted in the detail of the auspicious events which led him gradually to his exalted destiny. At the little town of Yalmont, near the residence of the Count d’Hericy, a society used to meet for the purpose of discussing points connected with the most im- portant public question of the locality, viz. its agriculture. At this so- ciety an individual of the place usually took a leading part; and it was not long before the penetrating tutor recognised in him a contributor on this subject to the Encyclopedic Methodique, then a highly popular scientific work, published in Paris. Cuvier, in the ardour of an energetic spirit, MEMOIR. Ill made known to this individual the nature of his discovery, when the latter exclaimed, “ Then I am lost!” “ Lost?” replied the young man; “ no, no; henceforth you shall be the object of my anxious care.” The fact was, that the person spoken of was M. Tessier, who wras resident at the place in question in a disguised character, having fled from Paris to avoid the dangerous chances of the reign of terror. Through M. Tessier, the aspiring young naturalist had the gratification of opening a correspondence with the most celebrated naturalists of the day. In the spring of 1795, the reflecting portion of the Parisian commu- nity saw the necessity of making some attempt at restoring at least the literary institutions, which with every other means of utility had fallen in the recent revolutionary devastation. Cuvier had laid such a foundation for the eminence of his character by this time, as to be received into the select few who were to take a practical part in the great work of intel- lectual renovation ; and, being invited to Paris, was at once appointed Commissioner of Arts, and Professor at the Central School of the Pan- theon. Shortly afterwards, M. Mertrud, who had occupied the chair of Comparative Anatomy, finding the duties of his situation too fatiguing for a person of his advanced age, obtained the consent of his colleagues, the illustrious triumvirate, Jussieu, Geoflroy, and Lacepede, to appoint Cuvier as his assistant. In this fortunate promotion, Cuvier saw that he had passed the portals of that high way of fame to which all his ambition had been directed. It was towards the close of 1795, that he fixed his residence at the Gar- den of Plants, and a moment did not pass after he became master of a comfortable home, before he determined on sharing it with his aged father and his brother, the only members remaining of his immediate family. In a letter, which is found prefixed to the first volume of his Compa- rative Anatomy, and which was addressed by Cuvier to Mertrud, he re- fers to various circumstances connected with this critical epoch of his career. John Claude Mertrud held the situation of Demonstrator of Anatomy in the Garden of Plants, from 1750 up to the period when he was appointed Professor of Comparative Anatomy. He assisted Dauben- ton in the great Natural History; and his services to BufFon are recorded by the latter in terms such as the highest esteem and the warmest affec- tion alone could dictate. In this epistle Cuvier particularly refers to the progress which comparative anatomy was then making; and he shewed how the learned men formerly connected with the National Museum of Natural History, at Paris, strove to aid and promote that science. With respect to those who then filled the offices of the former, Cuvier thus addresses his friend and master: — “The learned men who compose the b 2 IV MEMOIR. present administration of the Museum, are worthy of imitating the glo- rious examples of their predecessors. I have received from them, as well as from you, all the assistance I could have expected from an en- lightened love for science, rendered more grateful by all the attentions the most generous friendship could suggest. Nothing has been spared that could lead to discoveries, or to the completion of the system of our know- ledge in comparative anatomy. The correspondents of the Museum have imitated the example of its depositaries. Citizen Baillon, in parti- cular, so well known by the valuable observations which he furnished to Buffon, and by those which he continues to make, procured me, with un- exampled zeal and generosity, the rarest birds and fishes. Citizen Hom- bert, of Havre, who has applied, with the greatest success, to the study of Mollusca and Sea Worms, has favoured me with a great number of these animals, the perfect preservation of which rendered their examina- tion exceedingly useful. Citizens Beauvois, Bose, and Olivier, the two first returned from North America, the third from Egypt and Persia, have kindly communicated to me some of the valuable specimens they have brought to Europe. I have, therefore, no reason to envy the good fortune of Aristotle, when a conqueror, who was the friend of the sciences, made other men subservient to him, and placed millions at his disposal, to enable him to forward the history of Nature. “ This assertion will not surprise, -when it is known that I have been permitted to dissect, not only the animals which have died in the mena- gerie, but also those which have been brought, during a great number of years, from all parts of the world, and preserved in spirits. Time only was capable of bringing this collection to its present degree of perfection, and has, in this instance, performed what no other power was capable of accomplishing. “ In opening to me your treasures — in admitting me to a share of the labours necessary to their arrangement and their augmentation, you have imposed upon me only one condition : that is, to enable other naturalists to enjoy them, by giving such a description of them as they merit. You know with what assiduity I endeavour to perform this task, but you also know better than any other what time such a work requires. However rich may be the acquisitions that are made, more will still be desired. Sometimes a new species is discovered, which we wish to compare with those we already know. Sometimes the consideration of an organ induces us to make further attempts to develope its structure. On other occa- sions it is necessary to extend our observations ; because something re- mains to be learned respecting the object as a whole, or the relation of its parts. In natural history, in particular, we are always dissatisfied with what we perform, for Nature proves to us, at each step, that she is inex- haustible.” MEMOIR. V The French. National Institute, which has been so powerful an engine in the diffusion of a taste for natural history, was instituted in 1796, and amongst its founders the name of Cuvier is conspicuous. The first of his contributions to the literature of science bears the date of 1792; several detached papers were, about this period, written and published by him in periodical journals, and in them we trace the commencement of that powerful devotion to fossil anatomy, which he subsequently elevated into such an empire of natural wonders. The first of his more extended and important works was the “ Tableau Elernentaire of the Natural His- tory of Animals,” which he published in 1798. In his capacity of assistant to M. Mertrud, Cuvier had to deliver lectures on Comparative Anatomy; and so valuable were they deemed, that a favourite and able pupil of his, M. Dumeril, was induced to take notes of them, which, with the author’s sanction and assistance, he placed before the public. They form the first two volumes of the Comparative Anatomy of Cuvier. The “ Tableau,” just alluded to, was the rudimental form in which the great principles of classification founded by Cuvier were fully developed. In detached memoirs, such as that on the circulation of White-blooded Animals, he had already supplied some knowledge of those principles; but it was only in the larger work that he had entered upon the general plan of classification, which was to rest, perhaps for ever, on the ruins of the Linnaean system. In 1800, Cuvier succeeded Mertrud, and resigned the chair of the Central School of the Pantheon. When the expedition to Egypt was contemplated, Cuvier was amongst the savants who had been nominated as fit to accompany the army, in the capacity of naturalists. But he declined the compliment, having the at- tractions at home, by which were provided for him a quiet life, and un- bounded facilities for his favourite study. When Bonaparte assumed the office of President of the National Institute, he selected Cuvier as one of the six individuals who were to act as Inspectors-General, for the purpose of establishing Lyceums for education in thirty towns of France, and in this character he established useful seminaries for youth in Marseilles, Nice, and Bordeaux, which still flourish under the title of Royal Colleges. Whilst he was engaged in this important duty, a change of the constitu- tion of the National Institute was effected, whereby the secretaryships were made perpetual; and Cuvier being raised to that of the National Sciences, it remained in his hands up to the period of his death. The father of Cuvier having died from a fall, an event which was soon followed by the premature death of his brother’s wife, his home was no longer that centre of domestic comfort which he had found it before. The natural resource of a refined and prudent man placed in such a condition VI MEMOIR. as this was resorted to by Cuvier, and a matrimonial alliance was formed by him in 1803. The lady whom he selected as his partner for life, wras the widow of M. Duvaucel, a fermier general, who fell a sacrifice to the fury of the revolutionary rabble in 1794. The circumstances under which he chose Mrs. Duvaucel for his wife, are at once decisive of the disinterested feelings which accompanied the resolution ; for the calamity to which her late husband had become a victim extended to his fortunes, and only a wreck of what she once was fell to the lot of Cuvier. Nay, he saw, that by the alliance a burden would be placed upon his industry; for the widow had under her protection four children, the fruit of her first marriage. But though these accompaniments formed very powerful objections, as well they might, to a union of his destinies, on the part of Cuvier, with this female, still he saw in her mind and feelings an abundance of what was calculated to make him forget those objections. The four children of the former marriage met with a very various des- tiny. One was assassinated during the retreat of the French army from Portugal, in the memorable campaign of 1809: a second, who had fol- lowed the example of his illustrious step-father, and encountered perils and fatigues in pursuit of science, exhausted his vital powers by a vain attempt to defy the deleterious influence of an uncongenial climate : he died in Madras. The third of the sons of Madame Duvaucel is still living, an officer of customs at Bordeaux ; and his sister, the last of the children, performed the amiable duties of nurse to the illustrious object of all the anxious cares of his family, and remains as the chief source of consolation to the old age of her mother. Madame Cuvier, besides the three sons and daughter just spoken of, had four children more whilst married to her last husband, but, unhappily, both the parents survived them all. There is no one, therefore, now in existence, to whom we can look as the hereditary successor of Cuvier’s peculiar intellect; that great, and to his fellow-creatures, most beneficial endowment, ceased with his life-breath, and is buried, we fear, with him in his grave. In the mean time, as a public man, Cuvier was the object of fresh ho- nours, the testimonies of the increasing esteem which his labours had earned. In 1809, Napoleon appointed him to the office of Councillor of the Imperial University, which that emperor had created; and, in this character, Cuvier was entrusted with the establishment of new seminaries of instruction in that branch of the French empire which, for a season, consisted of several Italian states. The principles which he laid down for the constitution and government of these asylums of science, receive their best panegyric from the circumstance that they were perpetuated by the succeeding governments, who could not have been interested in the pre- servation of national memorials so adverse to their own interest. MEMOIR. Vll The extent to which the time of Cuvier was employed, in consequence of his appointments by Napoleon in political affairs, was such as to induce us to conclude that he found it necessary to abandon the pursuit of science. But the real truth appears to be, that, whilst he scrupulously fulfilled his obligations as a public functionary, he made the very occasions in which he was occupied in that capacity subservient to the one ulterior object of his life; and the affairs connected with the establishment of se- minaries in Marseilles and Bordeaux were only so many inducements to him to proceed to the sea shore, there to behold and to investigate his favourite department of the animal series — the Mollusca tribes. We have mentioned, that the labours of Cuvier in the department of comparative anatomy had been completed in 1805, by the publication of the three successive volumes as the sequel of the first two which appeared in 1800. The knowledge which he acquired by his labours in this de- partment proved the source of some of the most memorable triumphs of his genius; amongst which we may especially mention his grand re- searches on the fossil remains of the bones of animals. The history of the causes which led Cuvier to the investigation of the geology of the site of Paris is amongst the most curious and agreeable chapters in the annals of science. Up to a very recent period, not only in France, but also in England, the conclusions to which the celebrated German, Werner, had come, in the science of mineralogy, appeared to leave nothing to be done for the further elucidation of the knowledge of the crust of the earth. His sys- tem comprised, it was thought, the most perfect explanation of the whole series of the strata of that crust ; and the scientific world seemed to think it a work of superfluity to attempt to add new facts to the series which that naturalist had collected in reference to this subject. But, as edu- cation, assisted by the progress of the habit of a free exertion of mind, scattered abroad the contagion of a disposition to inquiry, the scientific men of Paris began to acknowledge, that, in the very heart of their city, in every inch of the soil upon which they daily trod, they saw before them a series of geological structures, of which the supposed infallible apostle of mineralogy had certainly predicated nothing whatever. A nearer in- spection of the phenomena, which powerfully arrested their attention, brought them at last to the conviction, that either they were incapable of making a due application of the system of Werner, or that that system was altogether inadequate to expound the whole of what it undertook to explain with satisfaction. The savants of Paris, thus forced in self-de- fence to the task of inquiry, directed their own and their pupils’ attention to the German and Swiss mountains, and they wrere ultimately prevailed upon to render justice to science, through the influences which arose from VU1 MEMOIR. tlie grand progress of comparative anatomy, its pioneer being the immor- tal naturalist of the present memoir. In the last years of the late, and during the early part of the present century, the professors of the Garden of Plants, and of most other estab- lishments of Paris, where the teaching of comparative anatomy formed a part of the sciences which were taught, had frequently brought to their at- tention either skeletons, or detached portions of skeletons, dug up from beneath the soil of the city, evidently the relics of animals, and, in com- parison with which, the bony structures of the present race of living beings were altogether on a different scale. The comparative anatomists of the Parisian schools would have lost their reputation, as well as their hearers, were they to allow these discoveries to pass for objects inexpli- cable by human penetration, particularly as every day brought forth, in the neighbourhood of the city, some object that was calculated still further to perplex the mystery of its origin. At last, the multitude of these spe- cimens was such as to reach the power of irritating the pride of Cuvier ; and that chivalrous champion of Nature’s jurisdiction said that there was no alternative but to grapple with the apparition, and ascertain at once its nature and properties. Cuvier, in association with M. A. Brongniart, proceeded to the investigation of the soil, and, after many a laborious year of toil and fatigue in quarries, caverns, &c., after many a tedious ascent up the heights of Montmartre, the indefatigable inquirers collected such a body of information, as at once shed abundant light upon the phe- nomena that had perplexed the scientific world so long. The results were published in 1812, in a large work on the fossil bones, which has since been reproduced with such improvements as to render it, ac- cording to the opinion expressed by one of the most celebrated of the geologists of this country (Mr. Bakewell), “ the most luminous and inte- resting exposition of local geology ever presented to the world.” The great authority just mentioned adds, that it is from the era of this publi- cation that we are to date the first accurate knowledge, of what is called by geologists, the “ tertiary strata*.” From the work on fossil organic remains just mentioned, the conclusion is obvious, that Cuyier was the first, who, by the application of the rarest * The high place assigned by the learned of all countries to this great composi- tion, has induced the proprietor of the present translation of the “ Animal Kingdom,” to prepare a version of the last edition of the “ Fossil Bones” of the same cele- brated author. This is the work which exhibits the wonderful genius of Cuvier in its most triumphant exertion; and it is only surprising that British enterprize, in all that regards the advancement of science, should not, ere this, have secured to our scientific literature a source of knowledge of so much consequence. The translation here announced, and its multitude of graphic illustrations,, will be on the same ex- pensive scale to the proprietor, and the same economical one to the public, as have been adopted in the present work. MEMOIR. IX powers of observation and reflection, and by an unequalled ingenuity, con- verted comparative anatomy into a sort of talisman for unfolding the won- ders of the osseous contents which lay for ages in the caverns of the earth. His researches on the fossil bones, as they now appear in the work to which we have just alluded, form an epoch in the annals of geology, that yields to no part of its history in deep and durable interest ; nor has even the great author himself of this important discovery which he has made in his beautiful scheme of exposition, failed to consider it to be a source of wonder, as it was of pride, to his own heart. “ When,” said he, “ the sight of some bones of the bear and the elephant, twelve years ago, in- spired me with the idea of applying the general laws of comparative ana- tomy to the reconstruction and the discovery of fossil species ; when I began to perceive that these species were not perfectly represented by those of our day, which resembled them the most, I did not suspect that I was every day treading upon a soil, filled with remains more extraordi- nary than any that I had yet seen; nor that I was destined to bring to light whole genera of animals unknown to the present world, and buried for incalculable ages at vast depths under the earth. It was to M. Yeurin that I owe the first indications of these bones furnished by our quarries : some fragments which he brought me one day having struck me with as- tonishment, I made inquiries respecting the persons to whom this indus- trious collector had sent any formerly : what I saw in these collections served to excite my hopes and increase my curiosity. Causing search to be made at that time for such bones in all the quarries, and offering re- wards to arouse the attention of the workmen, I collected a greater num- ber than any person who had preceded me. After some years I was suf- ficiently rich in materials to have nothing further to desire; but it was otherwise with respect to their arrangement and the construction of the skeletons, which alone could conduct me to a just knowledge of the spe- cies. From the first moment, I perceived that there were many different species in our quarries ; and soon afterwards, that they belonged to various genera, and that the species of the different genera were often of the same size ; so that the size alone rather confused than assisted my arrange- ment.

As correct ideas respecting natural history are not very generally formed, it appears necessary to begin by defining its peculiar object, and establish- ing rigorous limits between it and neighbouring sciences. In our language, and in most others, the word nature is variously em- ployed. At one time it is used to express the qualities a being derives from birth, in opposition to those it may owe to art ; at another, the entire mass of beings which compose the universe; and at a third, the laws which'1 govern those beings. It is in this latter sense particularly that we usually personify nature, and, through respect, use its name for that of its Creator. Physics, or Natural Philosophy, treats of the nature of these three re- lations, and is either general or particular. General physics examines abstractedly each of the properties of those moveable and extended beings we call bodies. That branch of them styled Dynamics, considers bodies in mass ; and, proceeding from a very small number of experiments, de- termines mathematically the laws of equilibrium, and those of motion and of its communication. Its different divisions are termed Statics, Hydro- statics, Hydrodynamics, Mechanics, &c. &c., according to the nature of the particular bodies whose motions it examines. Optics considers the particular motions of light, whose phenomena, which hitherto nothing but experiment has been able to determine, are becoming more numerous. Chemistry, another branch of general physics, exposes the laws by which the elementary molecules of bodies act on each other; the combinations or separations which result from the general tendency of these molecules to re -unite ; and the modifications which the various circumstances capable of separating or approximating them produce on that tendency. It is purely a science of experiment, and is irreducible to calculation. The theory of heat and that of electricity belong either to dynamics or chemistry, according to the point of view in which they are considered. VOL. i. A 2 INTRODUCTION. The ruling method in all the branches of general physics consists in isolating bodies, reducing them to their greatest simplicity, in bringing each of their properties separately into action, either by reflection or ex- periment, and by observing or calculating the results ; and finally, in gene- ralising and connecting the laws of these properties, so as to form codes, and, if it were possible, to refer them to one single principle into which they might all be resolved. The object of Particular Physics , or of Natural History — for the terms are synonymous — is, the special application of the laws recognised by the various branches of general physics to the numerous and varied beings which exist in nature, in order to explain the phenomena which each of them presents. Within this extensive range, Astronomy also would be included; but that science, sufficiently elucidated by mechanics, and completely sub- jected to its laws, employs methods, differing too widely from those re- quired by natural history, to permit it to be cultivated by the students of the latter. Natural history, then, is confined to objects which do not allow of exact calculation, nor of precise measurement in all their parts. Meteorology also is subtracted from it and united to general physics ; so that, properly speaking, it considers only inanimate bodies called minerals, and the dif- ferent kinds of living beings, in all of which we may observe the effects, more or less various, of the laws of motion and chemical attraction, and of all the other causes analysed by general physics. Natural history, in strictness, should employ similar methods with the general sciences; and it does so, in fact, whenever the objects it examines are sufficiently simple to allow it. This, however, is but very rarely the case. An essential difference between the general sciences and natural history is, that, in the former, phenomena are examined, whose conditions are all regulated by the examiner, in order, by their analysis, to arrive at general laws ; whereas, in the latter, they take place under circumstances beyond the control of him who studies them for the purpose of discovering, amid the complication, the effects of known general laws. He is not, like the experimenter, allowed to subtract them successively from each condition, and to’ reduce the problem to its elements — he is compelled to take it in its entireness, with all its conditions at once, and can perform the analysis only in thought. Suppose, for example, we attempt to insulate the nu- merous phenomena which compose the life of any of the higher orders of animals ; a single one being suppressed, every vestige of life is annihi- lated. Dynamics have thus nearly become a science of pure calculation; che- INTRODUCTION. 3 mistry is still a science of pure experiment ; and natural history, in a great number of its branches, will long remain one of pure observation. These three terms sufficiently designate the methods employed in the three branches of the natural sciences ; hut in establishing between them very different degrees of certitude, they indicate, at the same time, the point to which they should incessantly tend, in order to attain nearer and nearer to perfection. Calculation, if we may so express it, thus commands nature, and deter- mines her phenomena more exactly than observation can make them known ; experiment compels her to unveil ; while observation pries into her secrets when refractory, and endeavours to surprise her. There is, however, a principle peculiar to natural history, which it uses with advantage on many occasions ; it is that of the conditions of existence , commonly styled final causes. As nothing can exist without the re-union of those conditions which render its existence possible, the component parts of each being must be so arranged as to render possible the whole being, not only with regard to itself but to its surrounding relations. The analysis of these conditions frequently conducts us to general laws, as cer- tain as those that are derived from calculation or experiment. It is only when all the laws of general physics and those which result from the conditions of existence are exhausted, that we are reduced to the simple laws of observation. The most effectual method of obtaining these, is that of comparison. This consists in successively observing the same bodies in the different positions in which nature places them, or in a mutual comparison of dif- ferent bodies ; until we have ascertained invariable relations between their structures and the phenomena they exhibit. These various bodies are kinds of experiments ready prepared by nature, who adds to or deducts from each of them different parts, just as we might wish to do in our labo- ratories ; shewing us, herself, at the same time their various results. In this way we finally succeed in establishing certain laws by which these relations are governed, and which are employed like those that are determined by the general sciences. The incorporation of these laws of observation with the general laws, either directly or by the principle of the conditions of existence, would complete the system of the natural sciences, in rendering sensible in all its parts the mutual influence of every being. To this end, should those who cultivate these sciences direct all their efforts. All researches of this nature, however, pre -suppose means of distin- guishing clearly, and causing others to distinguish, the bodies they are occupied with; otherwise we should be continually confounding them. Natural history then should be based on what is called a system of nature — a 2 4 INTRODUCTION. or, a great catalogue, in which all created beings have suitable names, may be recognised by distinctive characters, and be arranged in divisions and subdivisions, themselves named and characterised, in which they may be found. In order that each being may be recognised in this catalogue, it must be accompanied by its character : habits or properties, which are but mo- mentary, cannot, then, furnish characters— -they must be drawn from the conformation. There is scarcely a single being which has a simple character, or can be recognised by one single feature of its conformation ; a union of several of these traits are almost always required to distinguish one being from those that surround it, who also have some but not all of them, or who have them combined with others of which the first is destitute. The more numerous the beings to be distinguished, the greater should be the number of traits ; so that to distinguish an individual being from all others, a complete de- scription of it should enter into its character. It is to avoid this inconvenience, that divisions and subdivisions have been invented. A certain number only of neighbouring beings are com- pared with each other, and their characters need only to express their dif- ferences, which, by the supposition itself, are the least part of their con- formation. Such a re-union is termed a genus. The same inconvenience would be experienced in distinguishing genera from each other, were it not for the repetition of the operation in uniting the adjoining genera, so as to form an order , the orders to form a class , &c. Intermediate subdivisions may also be established. This scaffolding of divisions, the superior of which contain the inferior, is called a method. It is in some respects a sort of dictionary, in which we proceed from the properties of things to arrive at their names ; being the reverse of the common ones, in which we proceed from the name to arrive at the property. When the method is good, it does more than teach us names. If the subdivisions have not been established arbitrarily, but are based on the true fundamental relations, on the essential resemblances of beings, the method is the surest means of reducing the properties of beings to general rules, of expressing them in the fewest words, and of stamping them on the memory. To render it such, we employ an assiduous comparison of beings, di- rected by the principle of the subordination of characters, which is itself derived from that of the conditions of existence. The parts of a being pos- sessing a mutual adaptation, some traits of character exclude others, while, on the contrary, there are others that require them. When, therefore, we perceive such or such traits in a being, we can calculate before hand those that co-exist in it, or those that are incompatible with them. The parts, INTRODUCTION. 5 the properties, or the traits of conformation, which have the greatest num- ber of these relations of incompatibility or of co-existence with others, or, in other words, that exercise the most marked influence upon the whole of the being, are called the important characters , dominating characters; the others are the subordinate characters, all varying in degree. This influence of characters is sometimes determined rationally, by the consideration of the nature of the organ. When this is impracticable, we have recourse to simple observation ; and a sure mark by which we may recognise the important characters, and one which is drawn from their own nature, is their superior constancy, and that in a long series of different beings, approximated according to their degrees of similitude, these cha- racters are the last to vary. That they should be preferred for distin- guishing the great divisions, and that, in proportion as we descend to the inferior subdivisions, we can also descend to subordinate and variable char- acters, is a rule resulting equally from their influence and constancy. There can be but one perfect method, which is the natural method. We thus name an arrangement in which beings of the same genus are placed nearer to each other than to those of the other genera; the genera of the same order nearer than those of the other orders, &c. &c. This method is the ideal to which natural history should tend ; for it is evident that if we can reach it, we shall have the exact and complete expression of all nature. In fact, each being is determined by its resemblance to others, and difference from them ; and all these relations would be fully given by the arrangement in question. In a word, the natural method would be the whole science, and every step towards it tends to advance the science to perfection. Life being the most important of all the properties of beings, and the highest of all characters, it is not surprising that it has in all ages been made the most general principle of distinction; and that natural beings have always been separated into two immense divisions, the living and the inanimate. Of Living Beings , and Organization in general. If, in order to obtain a correct idea of the essence of life, we consider it in those beings in which its effects are the most simple, we quickly perceive that it consists in the faculty possessed by certain corporeal combinations, of continuing for a time and under a determinate form, by constantly at- tracting into their composition a part of surrounding substances, and ren- dering to. the elements portions of their own. Life then is a vortex, more or less rapid, more or less complicated, the direction of which is invariable, and which always carries along molecules of similar kinds, but into which individual molecules are continually entering, 6 INTRODUCTION. and from whicli they are continually departing ; so that the form of a living body is more essential to it than its matter. As long as this motion subsists, the body in which it takes place is living — it lives. When it finally ceases, it dies. After death, the ele- ments which compose it, abandoned to the ordinary chemical affinities, soon separate, from which, more or less quickly, results the dissolution of the once living body. It was then by the vital motion that its dissolution was arrested, and its elements were held in a temporary union. All living bodies die after a certain period, whose extreme limit is fixed for each species, and death appears to be a necessary consequence of life, which, by its own action, insensibly alters the structure of the body, so as to render its continuance impossible. In fact, the living body undergoes gradual, but continual changes, dur- ing the whole term of its existence. At first, it increases in dimensions, ac- cording to proportions, and within limits, fixed for each species and for each one of its parts ; it then augments in density in the most of its parts — it is this second kind of change that appears to be the cause of natural death. If we examine the various living bodies more closely, we find they pos- sess a common structure, which a little reflection soon causes us to per- ceive is essential to a vortex, such as the vital motion. Solids, it is plain, are necessary to these bodies, for the maintenance of their forms ; and fluids for the conservation of motion in them. Their tissue, accordingly, is composed of network and plates, or of fibres and so- lid laminae, within whose interstices are contained the fluids ; it is in these fluids that the motion is most continued and extended. Foreign substan- ces penetrate the body and unite with them ; they nourish the solids by the interposition of their molecules, and also detach from them those that are superfluous. It is in a liquid or gaseous form that the matters to be exhaled traverse the pores of the living body ; but in return, it is the so- lids which contain the fluids, and by their contraction communicate to them part of their motion. This mutual action of the fluids and solids, this transition of molecules, required considerable affinity in their chemical composition; and such is the fact — the solids of organized bodies being mostly composed of ele- ments easily convertible into fluids or gases. The motion of the fluids needing also a constantly repeated action on the parts of the solids, and communicating one to them, required in the latter both flexibility and dilatibility ; and accordingly we find this charac- ter nearly general in all organized solids. This structure, common to all living bodies ; this areolar tissue, whose more or less flexible fibres or laminae intercept fluids more or less abund- ant; constitutes what is called the organization. As a consequence of INTRODUCTION. 7 what we have said, it follows, that life can be enjoyed by organized bodies only. Organization, then, results from a great variety of arrangements, which are all conditions of life ; and it is easy to conceive, that if its effect be to alter either of these conditions, so as to arrest even one of the partial mo- tions of which it is composed, the general movement of life must cease. Every organized body, independently of the qualities common to its tis- sue, has a form peculiar to itself, not merely general and external, but ex- tending to the detail of the structure of each of its parts ; and it is upon this form, which determines the particular direction of each of the partial movements that take place in it, that depends the complication of the ge- neral movement of its life — it constitutes its species and renders it what it is. Each part co-operates in this general movement by a peculiar action, and experiences from it particular effects, so that in every being life is a whole, resulting from the mutual action and re-action of all its parts. Life, then, in general, pre-supposes organization in general, and the life proper to each individual being pre-supposes an organization peculiar to that being, just as the movement of a clock pre-supposes the clock; and accordingly we behold life only in beings that are organized and formed to enjoy it, and all the efforts of philosophy have never been able to discover matter in the act of organization, neither per se, nor by any external cause. In fact, life exercising upon the elements which at every moment form part of the living body, and upon those which it attracts to it, an ac- tion contrary to that which, without it, would be produced by the usual che- mical affinities, it seems impossible that it can be produced by these affini- ties, and yet we know of no other power in nature capable of re-uniting previously separated molecules. The birth of organized beings is, therefore, the greatest mystery of the organic economy and of all nature : we see them developed, but never be- ing formed ; nay more, all those whose origin we can trace, have at first been attached to a body similar in form to their own, but which was deve- loped before them — in a word, to a parent. So long as the offspring has no independent existence, but participates in that of its parent, it is called a germ. The place to which the germ is attached, and the cause which detaches it, and gives it an independent life, vary ; but this primitive adhesion to a similar being is a rule without exception. The separation of the germ is called generation. Every organized being reproduces others that are similar to itself, other- wise, death being a necessary consequence of life, the species would be- come extinct. Organized beings have even the faculty of reproducing, in degrees vary- INTRODUCTION. 8 ing with the species, particular parts of which they may have been de- prived— this is called the power of reproduction . The developement of organized beings is more or less rapid, and more or less extended, as circumstances are more or less favourable. Heat, the abundance and species of nutriment, with other causes, exercise great in- fluence, and this influence may extend to the whole body in general, or to certain organs in particular : thence arises the impossibility of a perfect similitude between the offspring and parent. Differences of this kind, between organized beings, form what are termed varieties. There is no proof, that all the differences, which now distinguish or- ganized beings, are such as may have been produced by circumstances. All that has been advanced upon this subject is hypothetical. Experi- ence, on the contrary, appears to prove, that, in the actual state of the globe, varieties are confined within rather narrow limits, and go back as far as we may, we still find those limits the same. We are thus compelled to admit of certain forms, which, from the origin of things, have perpetuated themselves without exceeding these limits, and every being appertaining to one or other of these forms constitutes what is termed a species. Varieties are accidental subdivisions of species. Generation being the only means of ascertaining the limits to which va- rieties may extend, species should be defined — the re-union of individuals descended one from the other , or from common parents , or from such as resemble them as strongly as they resemble each other. But although this definition is strict, it will be seen that its application to particular in- dividuals may be very difficult, where the necessary experiments have not been made. Thus then it stands — absorption, assimilation, exhalation, developement, and generation, are functions common to all living bodies ; birth and death the universal limits of their existence ; an areolar, contractile tissue, con- taining within its laminae fluids or gases in motion, the general essence of its structure ; substances, almost all susceptible of conversion into fluids or gases, and combinations capable of an easy and mutual transformation, the basis of their chemical composition. Fixed forms that are perpetuated by generation distinguish their species, determine the complication of the se- condary functions proper to each of them, and assign to them the parts they are to play on the great stage of the universe. These forms are nei- ther produced nor changed by their own agency — life supposes their exist- ence, its flame can only be kindled in an organization already prepared, and the most profound meditation and lynx-eyed and delicate observation can penetrate no farther than the mystery of the pre-existence of germs. INTRODUCTION. 9 Division of Organized Beings into Animals and Vegetables. Living or organized beings have always been subdivided into animate beings , that is, such as are possessed of sense and motion ; and into inani- mate beings , which are deprived of both these faculties, and are reduced to the simple faculty of vegetating. Although the leaves of several plants shrink from the touch, and the roots are steadily directed towards mois- ture, the leaves to light and air, and though parts of vegetables appear to oscillate without any apparent external cause, still these various motions have too little similarity to those of animals, to enable us to find in them any proofs of perception or will. The spontaneity in the motions of animals required essential modifications even in their purely vegetative organs. Their roots not penetrating the earth, it was necessary they should be able to place within themselves a supply of aliment, and to carry its reservoir along with them. Hence is derived the first character of animals, or their alimentary canal, from which their nutritive fluid penetrates all other parts through pores or vessels, which are a kind of internal roots. The organization of this cavity and its appurtenances required varying, according to the nature of the aliment, and the operation it had to under- go, before it could furnish juices fit for absorption; whilst the air and earth present to vegetables nought but elaborated juices ready for ab- sorption. The animal, wdiose functions are more numerous and varied than those of the plant, consequently necessitated an organization much more com- plete ; besides this, its parts not being capable of preserving one fixed re- lative position, there were no means by which external causes could pro- duce the motion of their fluids, which required an exemption from, atmos- pheric influence ; from this originates the second character of animals — their circulating system , one less essential than that of digestion, since in the more simple animals it is unnecessary. The animal functions required organic systems not needed by vegetables — that of the muscles for volun- tary motion, and nerves for sensibility ; and these two systems, like the rest, acting only through the motions and transformations of the fluids, it was necessary that these should be most numerous in animals, and that the chemical composition of the animal body be more complex than that of the plant ; and so it is, for one substance more (azote) enters into it as an es- sential element, whilst in plants it is a mere accidental junction with the three other general elements of organization — oxygen, hydrogen, and car- bon. This then is the third character of animals. From the sun and atmosphere, vegetables receive for their nutrition, water, which is composed of oxygen and hydrogen ; air, which contains 10 INTRODUCTION. oxygen and azote ; and carbonic acid, which is a combination of oxygen and carbon. To extract their own composition from these aliments, it was necessary they should retain the hydrogen and carbon, exhale the super- fluous oxygen, and absorb little or no azote. Such, in fact, is vegetable life, whose essential function is the exhalation of oxygen, which is effected through the agency of light. Animals also derive nourishment, directly or indirectly, from the vege- table itself, in which hydrogen and carbon form the principal parts. To assimilate them to their own composition, they must get rid of the su- perabundant hydrogen and carbon in particular, and accumulate more azote, which is performed through the medium of respiration, by which the oxygen of the atmosphere combines with the hydrogen and carbon ot their blood, and is exhaled with them in the form of water and carbonic acid. The azote, whatever part of the body it may penetrate, seems al- ways to remain there. The relations of vegetables and animals to the surrounding atmosphere are therefore in an inverse ratio — the former reject water and carbonic acid, while the latter produce them. The essential function of the animal body is respiration, it is that which in a manner animalizes it, and we shall see that the animal functions are the more completely exercised in proportion to the greatness of the powers of respiration possessed by the animal. This difference of relations constitutes the fourth character of animals. Of the Forms 'peculiar to the Organic Elements of the Animal Body , and of the principal Combinations of its Chemical Elements. An areolar tissue and three chemical elements are essential to every living body ; there is a fourth element peculiarly requisite to that of an animal ; but this tissue is composed of variously formed meshes, and these elements are variously combined. There are three kinds of organic materials or forms of texture — the cel- lular membrane , the muscular fibre, and the medullary matter; and to each form belongs a peculiar combination of chemical elements, as well as a particular function. The cellular substance is composed of an infinity of small fibres and laminae, fortuitously disposed, so as to form little cells that communicate with each other. It is a kind of sponge, which has the same form as the body, all other parts of which traverse or fill it, and contracting indefi- nitely, on the removal of the causes of its tension. It is this power that retains the body in a given form and with certain limits. When condensed, this substance forms those laminae called membranes ; the membranes rolled into cylinders, form those more or less ramified tubes INTRODUCTION. 11 named vessels; tlie filaments, called fibres, are resolved into it; and bones are nothing but the same thing indurated by the accumulation of earth- ly particles. The cellular substance consists of a combination well known as gelatine, characterised by its solubility in boiling water, and forming, when cold, a trembling jelly. We have not yet been able to reduce the medullary matter to its or- ganic molecules ; to the naked eye, it appears like a sort of soft bouillie, consisting of excessively small globules ; it is not susceptible of any appa- rent motion, but in it resides the admirable power of transmitting to the me the impressions of the external senses, and conveying to the muscles the orders of the will. It constitutes the greater portion of the brain and the spinal marrow, and the neives which are distributed to all the sen- tient organs are, essentially, mere fasciculi of its ramifications. The fieshy, or muscular fibre, is a peculiar sort of filament, whose distinc- tive property, during life, is that of contracting when touched or struck, or when it experiences the action of the will through the medium of the nerve. The muscles, direct organs of voluntary motion, are mere bundles of fleshy fibres. All vessels and membranes which have any kind of com- pression to execute are armed with these fibres. They are always inti- mately connected with nervous threads, but those which belong to the purely vegetative functions contract, without the knowledge of the me, so that, although the will is truly a means of causing the fibres to act, it is neither general nor unique. The fleshy fibre has for its base a particular substance called fibrine , which is insoluble in boiling water, and which seems naturally to assume this filamentous disposition. The nutritive fluid or the blood, such as we find it in the vessels of the circulation, is not only mostly resolvable into the general elements of the animal body, carbon, hydrogen, oxygen, and azote, but it also contains fi- brine and gelatine, almost prepared to contract and to assume the forms of membranes or filaments peculiar to them, all that is ever wanted for their manifestation being a little repose. The blood also contains another com- bination, which is found in many animal fluids and solids, called albumen, whose characteristic property is that of coagulating in boiling water. Be- sides these, the blood contains almost every element which may enter into the composition of the body of each animal, such as the lime and phospho- rus which harden the bones of vertebrated animals, the iron from which it and various other parts receive their colour, the fat or animal oil which is deposited in the cellular substance to supple it, &c. All the fluids and solids of the animal body are composed of chemical elements found in the ] C) 1m INTRODUCTION. blood, and it is only by possessing a few elements more or less, that each of them is distinguished ; whence it is plain, that their formation entirely depends on the subtraction of the whole or part of one or more elements of the blood, and in some few cases, on the addition of some element from elsewhere. These operations, by which the blood nourishes the fluid or solid matter of all parts of the body, may assume the general name of secretions. This name, however, is often appropriated exclusively to the production of li- quids ; while that of nutrition is more especially applied to the formation and deposition of the matter necessary to the growth and conservation of the solids. The composition of every solid organ, of every fluid, is precisely such as fits it for the part it is to play, and it preserves it as long as health re- mains, because the blood renews it as fast it becomes changed. The blood itself by this continued contribution is changed every moment, but is re- stored by digestion, which renews its matter by respiration, which delivers it from superfluous carbon and hydrogen, by perspiration and various other excretions, that relieve it from other superabundant principles. These perpetual changes of chemical composition form a part of the vi- tal vortex, hot less essential than the visible movements and those of trans- lation. The object of the latter is, in fact, but to produce the former. Of the Forces which act in the Animal Body. The muscular fibre is not the only organ of voluntary motion, for we have just seen that it is also the most powerful of the agents employed by nature to produce those transmutations so necessary to vegetative life. Thus the fibres of the intestines produce the peristaltic motion, which causes the alimentary matter therein contained to pass through them; the fibres of the heart and arteries are the agents of the circulation, and through it of all the secretions, &e. Volition contracts the fibre through the medium of the nerve; and the involuntary fibres, such as those we have mentioned, being also animated by them, it is probable that these nerves are the cause of their con- traction. All contraction, and, generally speaking, every change of dimension in nature, is produced by a change of chemical composition, though it con- sist merely in the flowing or ebbing of an imponderable fluid, such as ca- loric; thus also are produced the most violent movements known upon earth, explosions, &c. There is, consequently, good reason to suppose that the nerve acts upon the fibre through the medium of an imponderable fluid, and the more so, as it is proved that this action is not mechanical. INTRODUCTION. n The medullary matter of the whole nervous system is homogeneous, and must he able to exercise its peculiar functions wherever it is found; all its ramifications are abundantly supplied with blood vessels. All the animal fluids being drawn from the blood by secretion, we can have no doubt that such is the case with the nervous fluid, and that the medullary matter secretes it. On the other hand, it is certain that the medullary matter is the sole conductor of the nervous fluid ; all the other organic elements restrain and arrest it, as glass arrests electricity. The external causes which are capable of producing sensations or caus ing contractions of the fibre are all chemical agents, capable of effecting decompositions, such as light, caloric, , the salts, odorous vapours, percus- sion, compression, &c. & c. It would appear then that these causes act on the nervous fluid chemi- cally, and by changing its composition ; this appears the more likely, as their action becomes weakened by continuance, as if the nervous fluid needed the resumption of its primitive composition to fit it for a fresh alteration. The external organs of the senses may be compared to sieves, which allow nothing to pass through to the nerve, except that species of agent which should affect it in that. particular place, but which often accumulates it so as to increase its effect. The tongue has its spongy papillae which imbibe saline solutions ; the ear, a gelatinous pulp which is violently agi- tated by sonorous vibrations ; the eye, transparent lenses which concen- trate the rays of light, &c. &c. It is probable, that what are styled irritants, or the agents which occa- sion the contractions of the fibre, exert this action by producing on the fibre, by the nerve, a similar effect to that produced on it by the will ; that is, by altering the nervous fluid, in the way that is requisite to change the dimensions of the fibre which it influences : but with this process the will has nothing to do, and very often the me is entirely ignorant of it. The muscles separated from the body preserve their susceptibility of irritation, as long as the portion of the nerve that remains with them preserves the power of acting on them — with this phenomenon the will has evidently no connexion. The nervous fluid is altered by muscular irritation, as well as by sen- sibility and voluntary motion, and the same necessity exists for the re- establishment of its primitive composition. The transmutations necessary to vegetable life are occasioned by irri- tants; the aliment irritates the intestine, the blood irritates the heart, &c. These movements are all independent of the will, and generally (while in health) take place without the knowledge of the me; in several parts, the 14 INTRODUCTION. nerves that produce them are even differently arranged from those that are appropriated to sensation, or dependent on the will, and the very object of this difference appears to be the securing of this independence. The nervous functions, that is, sensibility and muscular irritability, are so much the stronger at every point, in proportion as their exciting cause is abundant ; and as this cause, or the nervous fluid, is produced by secre- tion, its abundance must be in proportion to the quantity of medullary or secretory matter, and the amount of blood received by the latter. In animals that have a circulating system, the blood is propelled through the arteries which convey it to its destined parts, by means of their irrita- bility and that of the heart. If these arteries be irritated, they act more strongly, and propel a greater quantity of blood; the nervous fluid be- comes more abundant and augments the local sensibility ; this, in its turn, augments the irritability of the arteries, so that this mutual action may sometimes be carried to a great extent. It is called orgasm , and when it becomes painful and permanent, inflammation. The irritation may also originate in the nerve when exposed to the influence of acute sensations. This mutual influence of the nerves and fibres, either intestinal or ar- terial, is the real spring of vegetative life in animals. As each external sense is permeable only by such or such sensible sub- stances, so each internal organ may be accessible only to this or that agent of irritation. Thus, mercury irritates the salivary glands — cantharides irritate the bladder, &c. These agents are called specifics. The nervous system being homogeneous and continuous, local sensations and irritation debilitate the whole, and each function, by excessive action, may weaken the others. Excess of aliment weakens the power of thought, while long continued meditation impairs that of digestion, &c. Excessive local irritation will enfeeble the whole body, as if all the powers of life were concentrated in one single point. A second irritation produced at another part may diminish, or divert, as it is termed, the first : such is the effect of blisters, purgatives, &c. Brief as our sketch has been, it is sufficient to establish the possibility of accounting for all the phenomena of physical life, from the properties it presents, by the simple admission of a fluid such as we have defined. Summary Idea of the Functions and Organs of the Bodies of Animals , and of their various Degrees of Complication. After what we have stated respecting the organic elements of the body, its chemical principles and acting powers, nothing remains but to give a summary idea of the functions of which life is composed, and of their ap- propriate organs. INTRODUCTION. 15 The functions of the animal body are divided into two classes : The animal functions, or those proper to animals, that is to say, sensi- bility and voluntary motion. The vital, vegetative functions, or those common to animals and vege- tables, i. e., nutrition and generation. Sensibility resides in the nervous system. The most general external sense is that of touch ; it is seated in the skin, a membrane that envelopes the whole body, which is traversed in every direction by nerves whose extreme filaments expand on the surface into papillae, and are protected by the epidermis and other insensible tegu- ments, such as hairs, scales, &c. &c. Taste and smell are merely delicate states of the sense of touch, for which the skin of the mouth and nostrils is particularly organized : the first, by means of papillae more convex and spongy; the second, by its extreme delicacy and the multiplication of its ever humid surface. We have already spoken of the ear and the eye. The organ of generation is endowed with a sixth sense, seated in its in- ternal skin ; that of the stomach and intestines declares the state of those viscera by peculiar sensations. In fine, sensations more or less painful may originate in every part of the body through accident or disease. Many animals have neither ears nor nostrils, several are without eyes, and some are reduced to the single sense of touch, which is never absent. The action received by the external organs is continued by the nerves to the central masses of the nervous system, which, in the higher animals, consists of the brain and spinal marrow. The more elevated the nature of the animal, the more voluminous is the brain and the more is the sensitive power concentrated there ; the lower the animal, the more the medullary masses are dispersed, and in the most imperfect genera, the entire nervous substance seems to melt into the general matter of the body. That part of the body which contains the brain and principal organs of sense, is called the head. When the animal has received a sensation, and this has occasioned vo- lition, it is by the nerves, also, that this volition is transmitted to the muscles. The muscles are bundles of fleshy fibres whose contractions produce all the movements of the animal body. The extension of the limbs and every elongation, as well as every flexion and abbreviation of parts, are the ef- fects of muscular contraction. The muscles of every animal are arranged, both as respects number and direction, according to the movements it has to make; and when these motions require force, the muscles are inserted into hard parts, articulated one over another, and may be considered as so many levers. These parts are called bones in the vertebrated animals, where they are internal, and are formed of a gelatinous mass, penetrated 16 INTRODUCTION. by particles of phosphate of lime. In the Mollusca, the Crustacea, and Insects, where they are external, and composed of a calcareous or horny substance that exudes between the skin and epidermis, they are called shells, crusts, and scales. The fleshy fibres are attached to the hard parts by means of other fibres of a gelatinous nature, which seem to be a continuation of the former, constituting what are called tendons. The configuration of the articulating surfaces of the hard parts limits their motion, which are also restrained by cords or envelopes, attached to the sides of the articulations, called ligaments. It is from the various arrangements of this bony and muscular appara- tus, and the form and proportion of the members therefrom resulting, that animals are capable of executing the innumerable movements that enter into walking and leaping, flight and natation. The muscular fibres, appropriated to digestion and the circulation, are independent of the will ; they receive nerves, however, but the chief of them are subdivided and arranged in a manner which seems to have for its object their independence of the me. It is only in paroxysms of the pas- sions and other powerful affections of the soul, which break down these barriers, that the empire of the me is perceptible, and even then it is al- most always to disorder these vegetative functions. It is, also, in a state of sickness only that these functions are accompanied with sensations : di- gestion is usually performed unconsciously. The aliment, divided by the jaws and teeth, or sucked up when liquids constitute the food, is swallowed by the muscular movements of the hinder parts of the mouth and throat, and deposited in the first portions of the ali- mentary canal that are usually expanded into one or more stomachs ; there it is penetrated with juices fitted to dissolve it. Passing thence through the rest of the canal, it receives other juices destined to complete its pre- paration. The parietes of the canal are pierced with pores which extract from this alimentary mass its nutritious portion ; the useless residuum is rejected as excrement. The canal in which this first act of nutrition is performed, is a conti- nuation of the skin, and is composed of similar layers ; even the fibres that encircle it are analogous to those which adhere to the internal sur- face of the skin, called the fleshy pannicle. Throughout the whole inte- rior of this canal there is a transudation which has some connexion with the cutaneous perspiration, and which becomes more abundant when the latter is suppressed; the absorption of the skin is even very analogous to that of the intestines. It is only in the lowest order of animals that the ex- crements are rejected by the mouth, their intestines resembling a sac, having but one opening. INTRODUCTION. 17 Even among those where the intestinal canal has two orifices, there are many in which the nutritive juices, being absorbed by the parietes of the intestine, are immediately diffused throughout the whole spongy substance of the body: such, it would appear, is the case with all Insects. But from the Arachnides and Worms upwards, the nutritive fluid circulates in a system of closed vessels, whose ultimate ramifications alone dispense its molecules to the parts that are nourished by it; the vessels that convey it are called arteries , those that bring it back to the centre of the circulation, veins. The circulating vortex is here simple, and there double and even triple (including that of the vena-portae ) ; the rapidity of. its motion is often assisted by the contractions of a certain fleshy apparatus called a heart , which is placed at one or the other centres of circulation, and sometimes at both of them. In the red-blooded vertebrated animals, the nutritive fluid exudes from the intestines white or transparent, and is then termed chyle; it is poured into the veins, where it mingles with the blood, by a set of peculiar vessels called lacteals. Vessels similar to these lacteals, and forming with them an arrangement called the lymphatic system, also convey to the venous blood the residue of the nutrition of the parts and the products of cutaneous absorption. Before the blood is fit to nourish the parts, it must experience from the circumambient element the modification of which we have previously spoken. In animals possessing a circulating system, one portion of the vessels is destined to carry the blood into organs in which they spread it over a great surface to obtain an increase of this elemental influence. When that element is air, the surface is hollow, and is called lungs ; when it is water, it is salient, and is termed branchiae. There is always an ar- rangement of the organs of motion for the purpose of propelling the ele- ment into, or upon, the organ of respiration. In animals destitute of a circulating system, air is diffused through every part of the body by elastic vessels called tracheae; or water acts upon them, either by penetrating through vessels, or by simply bathing the surface of the skin. The respired or purified blood is properly quali- fied for restoring the composition of all the parts, and to effect what is pro- perly called nutrition. This facility, which the blood possesses, of decom- posing itself at every point, so as to leave there the precise kind of mole- cule necessary, is indeed wonderful; but it is this wonder which consti- tutes the whole vegetative life. For the nourishment of the solids we see no other arrangement than a great subdivision of the extreme arterial ra- mifications; but for the production of fluids the apparatus is more complex and various. Sometimes the extremities of the vessels simply spread themselves over large surfaces, whence the produced fluid exhales; at VOL. i. 18 INTRODUCTION. others it oozes from the bottom of little cavities. Before these arterial extremities change into veins, they most commonly give rise to particular vessels that convey this fluid, which appears to proceed from the exact point ol union between the two kinds of vessels; in this case the blood vessels and these latter form, by interlacing, particular bodies called con- glomerate or secretory glands. In animals that have no circulation, in insects particularly, the parts are all bathed in the nutritive fluid: each of these parts draws from it what it requires, and if the production of a liquid be necessary, proper ves- sels floating in the fluid take up, by their pores, the constituent elements of that liquid. It is thus that the blood incessantly supports the composition of all the parts, and repairs the injuries arising from those changes which are the continual and necessary consequences of their functions. The general ideas we form with respect to this process are tolerably clear, although we have no distinct or detailed notion of what passes at each point ; and for want of knowing the chemical composition of each part with sufficient precision, we cannot render an exact account of the transmutations neces- sary to effect it. Besides the glands which separate from the blood those fluids that are destined for the internal economy, there are some which detach others from it that are to be totally ejected, either as superfluous — the urine, for instance, which is produced by the kidneys ; or for some use to the animal — - as the ink of the cuttle-fish, and the purple matter of various mol- lusca, &c. With respect to generation, there is a process or phenomenon, infinitely more difficult to comprehend than that of the secretions — the production of the germ. We have even seen that it is to be considered as almost in- comprehensible ; but the existence of the germ being admitted, generation presents no particular difficulties. As long as it adheres to the parent, it is nourished as if it were one of its organs ; and when it detaches itself, it possesses its own life, which is essentially similar to that of the adult. The germ, the embryo, the foetus, and the new-born animal have never, however, exactly the same form as the adult, and the difference is some- times so great, that their assimilation has been termed a metamorphosis. Thus, no one not previously aware of the fact, would suppose that the ca- terpillar is to become a butterfly. Every living being is more or less metamorphosed in the course of its growth ; that is, it loses certain parts, and developes others. The anten- nae, wings, and all the parts of the butterfly were inclosed beneath the skin of the caterpillar ; this skin vanishes along with the jaws, feet, and other organs, that do not remain with the butterfly. The feet of the frog are INTRODUCTION. 19 inclosed by the skin of the tadpole ; and the tadpole, to become a frog, parts with its tail, mouth, and branchiae. The child, at its birth, loses its placenta and membranes ; at a certain period its thymus gland nearly dis- appears, and it gradually acquires hair, teeth, and beard ; the relative size of its organs is altered, and its body augments in a greater ratio than its head, the head more than the internal ear, &c. The place where these germs are found, and the germs themselves are collectively styled the ovary ; the canal through which, when detached, they are carried into the uterus, the oviduct; the cavity in which, in many species, they are compelled to remain for a longer or shorter period pre- vious to birth, the uterus; and the external orifice through which they pass into the world, the vulva. Where there are sexes, the male impreg- nates the germs appearing in the female. The fecundating liquor is called semen; the glands that separate it from the blood, testes ; and when, it is requisite it should be carried into the body of the female, the intro- ductory organ is named a 'penis . Of the Intellectual Functions of Animals. The impression of external objects upon the me, the production of a sensation or of an image, is a mystery into which the human understand- ing cannot penetrate ; and materialism an hypothesis, so much the more conjectural, as philosophy can furnish no direct proof of the actual exist- ence of matter. The naturalist, however, should examine what appear to be the material conditions of sensation, trace the ulterior operations of the mind, ascertain to what point they reach in each being, and assure himself whether they are not subject to conditions of perfection, dependent on the organization of each species, or on the momentary state of each individual body. To enable the me to perceive, there must be an uninterrupted commu- nication between the external sense and the central masses of the medul- lary system. It is then the modification only experienced by these masses that the me perceives : there may also be real sensations, without the ex- ternal organ being affected, and which originate either in the nervous chain of communication, or in the central mass itself; such are dreams and vi- sions, or certain accidental sensations. By central masses, we mean a part of the nervous system, that is so much the more circumscribed, as the animal is more perfect. In man, it consists exclusively of a limited portion of the brain ; but in reptiles, it includes the brain and the whole of the medulla, and of each of their parks taken separately, so that the absence of the entire brain does not prevent sensation. In the inferior classes this extension is still greater. The perception acquired by the me, produces the image of the sensation 20 INTRODUCTION. experienced. We trace to without the cause of that sensation, and thus acquire the idea of the object that has produced it. By a necessary law of our intelligence, all ideas of material objects are in time and space. The modifications experienced by the medullary masses leave impres- sions there which are reproduced, and thus recall to the mind images and ideas ; this is memory — a corporeal faculty that varies greatly, according to the age and health of the animal. Similar ideas, or such as have been acquired at the same time, recall each other ; this is the association of ideas. The order, extent, and quick- ness of this association constitute the perfection of memory. Every object presents itself to the memory with all its qualities or with all its accessary ideas. Intelligence has the power of separating these accessary ideas of objects, and of combining those that are alike in several different objects under a general idea; the object of which no where really exists, nor presents it- self per se — this is abstraction. Every sensation being more or less agreeable or disagreeable, experience and repeated essays soon shew what movements are required to procure the one and avoid the other ; and with respect to this, the intelligence abstracts itself from the general rules to direct the will. An agreeable sensation being liable to consequences that are not so, and vice versa , the subsequent sensations become associated with the idea of the primitive one, and modify the general rules framed by intelligence — this is prudence. From the application of these rules to general ideas, result certain for- mulas, which are afterwards easily adapted to particular cases — this is called reasoning. A lively remembrance of primitive and associated sensations, and of the impressions of pleasure or pain that belong to them, constitutes imagination. One privileged being, man, has the faculty of associating his general ideas with particular images more or less arbitrary, easily impressed upon the memory, and which serve to recall the general ideas they represent. These associated images are styled signs; their assemblage is a language. When the language is composed of images that relate to the sense of hear- ing, or of sounds , it is termed speech , and when relative to that of sight, hieroglyphics. Writing is a suite of images that relates to the sense of sight, by which we represent the elementary sounds, and by combining them, all the images relative to the sense of hearing of which speech is composed; it is therefore only a mediate representation of ideas. This faculty of representing general ideas by particular signs or images associated with them, enables us to retain distinctly, and to remember without embarrassment, an immense number ; and furnishes to the rea- INTRODUCTION. 21 soning faculty and the imagination innumerable materials, and to indivi- duals means of communication, which cause the whole species to participate in the experience of each individual, so that no bounds seem to be placed to the acquisition of knowledge — it is the distinguishing character of hu- man intelligence. Although, with respect to the intellectual faculties, the most perfect ani- mals are infinitely beneath man, it is certain that their intelligence per- forms operations of the same kind. They move in consequence of sensa- tions received, are susceptible of durable affections, and acquire by expe- rience a certain knowledge of things, by which they are governed inde- pendently of actual pain or pleasure, and by the simple foresight of con- sequences. When domesticated, they feel their subordination, know that the being who punishes them may refrain from so doing if he will, and, when sensible of having done wrong, or behold him angry, they assume a suppliant and deprecating air. In the society of man they "become either corrupted or improved, and are susceptible of emulation and jealousy ; they have among themselves a natural language, which, it is true, is merely the expression of their momentary sensations, but man teaches them to under- stand another, much more complicated, by which he makes known to them his will, and causes them to execute it. To sum up all, we perceive in the higher animals a certain degree of rea- son, with all its consequences, good and bad, and which appears to be about the same as that of children ere they have learned to speak. The lower we descend from man the weaker these faculties become, and at the bottom of the scale we find them reduced to signs (at times equivocal) of sensibi- lity, that is, to some few slight movements to escape from pain. Between these two extremes the degrees are infinite. In a great number of animals, however, there exists another kind of in- telligence, called instinct. This induces them to certain actions necessary to the preservation of the species, but very often altogether foreign to the apparent wants of the individual ; often also very complicated, and which, if attributed to intelligence, would suppose a foresight and knowledge in the species that perform them, infinitely superior to what can possibly be granted. These actions, the result of instinct, are not the effect of imita- tion, for very frequently the individuals who execute them have never seen them performed by others : they are not proportioned to ordinary intelli- gence, but become more singular, more wise, more disinterested, in propor- tion as the animals belong to less elevated classes, and in all the rest of their actions are more dull and stupid. They are so entirely the property of the species, that all its individuals perform them in the same way, with- out ever improving them a particle. The working bees, for instance, have always constructed very ingenious 22 INTRODUCTION. edifices, agreeably to the rules of the highest geometry, and destined to lodge and nourish a posterity not even their own. The solitary bee, and the wasp also, form highly^complicated nests, in which to deposit their eggs. From this egg comes a worm, which has never seen its parent, which is ig- norant of the structure of the prison in which it is confined, but which, once metamorphosed, constructs another precisely similar. The only method of obtaining a clear idea of instinct is by admitting the existence of innate and perpetual images or sensations in the sensorium, which cause the animal to act in the same way as ordinary or accidental sensations usually do. It is a kind of perpetual vision or dream that al- ways pursues it, and it may be considered, in all that has relation to its instinct, as a kind of somnambulism. Instinct has been granted to animals as a supplement to intelligence, to concur with it, and with strength and fecundity, in the preservation, to a proper degree, of each species. There is no visible mark of instinct in the conformation of the animal, but, as well as it can be ascertained, the intelligence is always in propor- tion to the relative size of the brain, and particularly of its hemispheres. Of Method , as applied to the Animal Kingdom. From what has been stated with respect to methods in general, we have now to ascertain what are the essential characters in animals, on which their primary divisions are to be founded. It is evident that they should be those which are drawn from the animal functions, that is, from the sen- sations and motions ; for both these not only make the being an animal, but in a manner establish its degree of animality. Observation confirms this position by shewing that their degrees of de- velopement and complication accord with those of the organs of the vege- tative functions. The heart and the organs of the circulation form a kind of centre for the vegetative functions, as the brain and the trunk of the nervous system do for the animal ones. Now we see these two systems become imperfect and disappear together. In the lowest class of animals, where the nerves cease to be visible, the fibres are no longer distinct, and the organs of di- gestion are simple excavations in the homogeneous mass of the body. In insects the vascular system even disappears before the nervous one ; but, in general, the dispersion of the medullary masses accompanies that of the muscular agents : a spinal marrow, on which the knots or ganglions repre- sent so many brains, corresponds to a body divided into numerous rings, supported by pairs of limbs longitudinally distributed, &c. This correspondence of general forms, which results from the arrange- ment of the organs of motion, the distribution of the nervous masses, and INTRODUCTION. 23 the energy of the circulating system, should then be the basis of the pri- mary divisions of the animal kingdom. We will afterwards ascertain, in each of these divisions, what characters should succeed immediately to those, and form the basis of the primary subdivisions. General Distribution of the Animal Kingdom into four great Divisions . If, divesting ourselves of the prejudices founded on the divisions former- ly admitted, we consider only the organization and nature of animals, with- out regard to their size, utility, the greater or less knowledge we have of them, and other accessary circumstances, we shall find there are four prin- cipal forms — four general plans, if it may be so expressed, on which all ani- mals seem to have been modelled, and whose ulterior divisions, whatever be the titles with which naturalists have decorated them, are merely slight modifications, founded on the developement or addition of certain parts, which produce no essential change in the plan itself. In the first of these forms, which is that of man, and of the animals most nearly resembling him, the brain and principal trunk of the nervous system are inclosed in a bony envelope, formed by the cranium and vertebrae ; to the sides of this intermedial column are attached the ribs, and bones of the limbs, which form the frame work of the body ; the muscles generally cover the bones, whose motions they occasion, while the viscera are contained within the head and trunk. Animals of this form we shall denominate Animalia Vertebrata. They have all red blood, a muscular heart, a mouth furnished with two jaws situated either above or before each other, distinct organs of sight, hearing, smell, and taste placed in the cavities of the face, never more than four limbs, the sexes always separated, and a very similar distribution of the medullary masses and the principal branches of the nervous system. By a closer examination of each of the parts of this great series of ani- mals, we always discover some analogy, even in species the most remote from each other ; and may trace the gradations of one same plan from man to the last of the fishes. In the second form there is no skeleton ; the muscles are merely at- tached to the skin, which constitutes a soft contractile envelope, in which, in many species, are formed stony plates, called shells, whose position and production are analogous to those of the mucous body. The nervous sys- tem is contained within this general envelope along with the viscera, and is composed of several scattered masses connected by nervous filaments; the chief of these masses is placed on the oesophagus, and is called the brain. Of the four senses, the organs of two only are observable, those of taste and sight, the latter of which are even frequently wanting. One single 24 INTRODUCTION. family alone presents organs of hearing. There is always, however, a complete system of circulation, and particular organs for respiration. Those of digestion and secretion are nearly as complex as in the verte- brata. We will distinguish the animals of this second form by the ap- pellation of Animalia Moliusca. Although, as respects the external configuration of the parts, the gene - ral plan of their organization is not as uniform as that of the vertebrata ; there is always an equal degree of resemblance between them in the struc- ture and the functions. The third form is that remarked in worms, insects, &c. Their nervous system consists of two long cords, running longitudinally through the ab- domen, dilated at intervals into knots or ganglions. The first of these knots, placed over the oesophagus, and called brain, is scarcely any larger than those that are along the abdomen, with which they communicate by filaments that encircle the oesophagus like a necklace. The covering or envelope of the body is divided by transverse folds into a certain number of rings, whose teguments are sometimes soft, and sometimes hard ; the muscles, however, being always situated internally. Articulated limbs are frequently attached to the trunk; but very often there are none. We will call these animals Animalia Articulata , Or, articulated animals, in which is observed the transition from the cir- culation in closed vessels to nutrition by imbibition, and the corresponding one of respiration in circumscribed organs, to that effected by tracheae or air vessels distributed throughout the body. In them, the organs of taste and sight are the most distinct ; one single family alone presenting that of hearing. Their jaws, when they have any, are always lateral. The fourth form, which embraces all those animals known by the name of zoophytes, may also properly be denominated Animalia Radiata , Or, radiated animals. We have seen that the organs of sense and mo- tion in all the preceding ones are symmetrically arranged on the two sides of an axis. There is a posterior and anterior dissimilar face. In this last division, they are disposed like rays round a centre ; and this is the case even when they consist of but two series, for then the two faces are similar. They approximate to the homogeneity of plants, having no very distinct nervous system or particular organs of sense ; in some of them, it is even difficult to discover a vestige of circulation ; their respiratory or- gans are almost universally seated on the surface of the body, the intestine in the greater number is a mere sac without issue, and the lowest of the INTRODUCTION. 25 series are nothing but a sort of homogeneous pulp, endowed with motion and sensibility*. * Before my time, modern naturalists divided all invertebrated animals into two classes, Insects and Worms. I was the first who attacked this method; and in a memoir read before the Society of Natural History of Paris on the 10th of May, 1795, and printed in the Decade Philosophique, I presented a new division, in which I marked the characters and limits of the Mollusca, Crustacea, Insects and Worms, Echinodermata and Zoophytes. In a memoir read before the Institute on the 31st of December, 1801, I ascertained the red-blooded worms or Annelides. And finally, in a memoir read before the Institute in July, 1812, and printed in the Annales du Museum d’Histoire Naturelle, tome xix, I distributed these various classes in three divisions, each of which is analogous to a branch of the vertebrata. FIRST GREAT DIVISION OF THE ANIMAL KINGDOM. ANXMALIA VERTEBRATA. The bodies and limbs of vertebrated animals being supported by a frame- work or skeleton, composed of connected pieces that are moveable upon each other, they have more precision and vigour in their motions. The soli- dity of this support enables them to attain considerable size, and it is among them that the largest animals are found. The great concentration of the nervous system, and the volume of its central portions, give energy and stability to their sensations, whence re- sult superior intelligence and perfectibility. Their body always consists of a head, trunk, and members. The head is formed by the cranium which contains the brain, and by the face which is composed of two jaws, and of the receptacles of the or- gans of the senses. The trunk is supported by the spine and the ribs. The spine is formed of vertebrae, the first of them supporting the head, which move upon each other, and are perforated by an annular opening, forming together a canal, in which is lodged that medullary production from which arise the nerves, called the spinal marrow. The spine, most commonly, is continued into a tail, extending beyond the posterior members. The ribs are a kind of semicircular hoops, which protect the sides of the cavity of the trunk; they are articulated at one extremity with the vertebrae, and most generally at the other with the sternum ; sometimes, however, they do not encircle the trunk, and there are genera in which they are hardly visible. There are never more than two pairs of limbs, but sometimes one or the other is wanting, or even both. Their forms vary according to the movements they have to execute. The anterior limbs may be modified into hands, feet, wings, or fins, and the posterior into feet or fins. The blood is always red, and appears to be so composed as to sustain a 28 ANIMALIA YERTEBRATA. peculiar energy of sentiment and muscular strength, but in various de- grees, corresponding to their quality of respiration : from which originates the subdivision of the Vertebrata into four classes. The external senses are always five in number, and reside in two eyes, two ears, two nostrils, the teguments of the tongue, and those of the body, generally. In some species, however, the eyes are obliterated. The nerves reach the medulla through the foramina of the vertebrae or those of the cranium ; they all seem to unite with this medulla, which, af- ter crossing its filaments, spreads out to form the various lobes of which the brain is composed, and terminates in the two medullary arches called hemispheres, whose volume is in proportion to the extent of the intelli- gence. There are always two jaws, the greatest motion is in the lower one, which rises and falls ; the upper jaw is sometimes immoveable. Both of these are almost always armed with teeth, excrescences of a peculiar na- ture, which in their chemical composition are very similar to that of bone, but which grow by layers and transudation; one whole class, however, that of birds, has the jaws invested with horn, and the genus Testudo, in the class of reptiles, is in the same case. The intestinal canal traverses the body from the mouth to the anus, ex- periencing various enlargements and contractions, having appendages and receiving solvent fluids, one of which, the saliva, is discharged into the mouth. The others, which are poured into the intestine only, have vari- ous names : the two principal ones are — the juices of the gland called the pancreas, and bile, a product of another very large gland named the liver. While the digested aliment is traversing its canal, that portion of it which is fitted for nutrition, called the chyle, is absorbed by particular ves- sels styled lacteals, and carried into the veins ; the residue of the nourish- ment of the parts is also carried into the veins by vessels analogous to these lacteals, and forming with them one same system, called the lympha- tic system. The blood which has served to nourish the parts, and which has just been renewed by the chyle and lymph, is returned to the heart by the veins — but this blood is obliged, either wholly or in part, to pass into the organ of respiration, in order to regain its arterial nature, previous to being again sent through the system by the arteries. In the three first classes this respiratory organ consists of lungs, that is, a collection of cells into which air penetrates. In fish only, and in some reptiles, while young, it consists of branchias or a series of laminae, between which water passes. In all the Vertebrata, the blood which furnishes the liver with the mate- rials of the bile is venous blood, which has circulated partly in the parietes of the intestines, and partly in a peculiar body called the spleen , and ANIMALIA VERTEBRATA. 29 which, after being united in a trunk called the vena-'portce , is again sub- divided at the liver. All these animals have a particular secretion ; the urine , which is pro- duced in two large glands, attached to the sides of the spine of the back, called kidneys — the liquid they secrete is most commonly poured into a reservoir, named bladder . The sexes are separate, and the female has always one or two ovaries, from which the eggs are detached at the instant of conception. The male fecundities them with the seminal fluid, but the mode varies greatly. In most of the genera of the three first classes, it requires an intromission of the fluid; in some reptiles, and in most of the fishes, it takes place after the exit of the egg. Subdivision of the Vertebrata into four Classes . We have just seen how far vertebrated animals resemble each other, they present, however, four great subdivisions or classes, characterised by the kind or power of their motions, which depend themselves on the quan- tity of their respiration, inasmuch as it is from this respiration that the muscular fibres derive the strength of their irritability. The quantity of respiration depends upon two agents : the first is the relative amount of blood which is poured into the respiratory organ in a given instant of time ; the second is the relative amount of oxygen which enters into the composition of the surrounding fluid. The quantity of the former depends upon the disposition of the organs of circulation and re- spiration. The organs of the circulation may be double, so that all the blood which is brought back from the various parts of the body by the veins, is forced to circulate through the respiratory organ, previous to resuming its former course through the arteries ; or they may be simple, so that a part only of the blood is obliged to pass through that organ, the remainder returning directly to the body. The latter is the case with reptiles. The quantity of their respiration, and all their qualities which depend on it, vary with the amount of blood thrown into the lungs at each pulsation. Fishes have a double circulation, but their organ of respiration is formed to execute its function through the medium of water; and their blood is only acted on by the portion of oxygen it contains, so that the quantity of their respiration is perhaps less than that of reptiles. In the mammalia the circulation is double, and the aerial respiration simple, that is, it is performed in the lungs only ; their quantity of respi- ration is, consequently, superior to that of reptiles, on account of the form ANIMALIA VERTEBRATA. SO of their respiratory organ, and to that of fishes, from the nature of their surrounding element. The quantity of respiration in birds is even superior to that of quadru- peds, not only because they have a double circulation and an aerial respi- ration, but also because they respire by many other cavities besides the lungs, the air penetrating throughout their bodies, and bathing the branches of the aorta, as well as those of the pulmonary artery. Hence result the four different kinds of motion for which the four classes of vertebrated animals are more particularly designed: quadrupeds, in which the quantity of respiration is moderate, are generally formed to walk and run, both motions being characterized by precision and vigour ; birds, which have more of it, possess the muscular strength and lightness requisite for flight ; reptiles, where it is diminished, are condemned to creep, and many of them pass a portion of their lives in a kind of torpor ; fishes, in fine, to execute their motions, require to be supported in a fluid whose specific gravity is nearly as great as their own. All the circumstances of organization peculiar to each of these four classes, and those especially which regard motion and the external sensa- tions, have a necessary relation with these essential characters. The mammalia, however, have particular characters in their viviparous mode of generation, in the manner by which the foetus is nourished in the uterus through the medium of the placenta, and in the mammae by which they suckle their young. The other classes, on the contrary, are oviparous, and if we compare them to the first, we shall find such numerous points of resemblance as announce a peculiar system of organization in the great general plan of the vertebrata. MAMMALIA. 31 CLASS I. MAMMALIA. The mammalia are placed at the head of the animal kingdom, not only because it is the class to which man himself belongs, hut also because it is that which enjoys the most numerous faculties, the most delicate sensa- tions, the most varied powers of motion, and in which all the different qualities seem combined in order to produce a more perfect degree of in- telligence, the one most fertile in resources, most susceptible of perfection, and least the slave of instinct. As their quantity of respiration is moderate, they are designed in gene- ral for walking on the earth, but with vigorous and continued steps. The forms of the articulations of their skeleton are, consequently, strictly de- fined, which determines all their motions with the most rigorous pre- cision. Some of them, however, by means of limbs considerably elongated, and extended membranes, raise themselves in the air; others have them so shortened, that they can move with facility in water only, though this does not deprive them of the general characters of the class. The upper jaw, in all of these animals, is fixed to the cranium; the lower is formed of two pieces only, articulated by a projecting condyle to a fixed temporal bone : the neck consists of seven vertebras, one single species excepted, which has nine ; the anterior ribs are attached before, by cartilage, to a sternum consisting of several vertical pieces ; their'1' an- terior extremity commences in a shoulder-blade that is not articulated, but simply suspended in the flesh, often resting on the sternum by means of an intermediate bone, called a clavicle. This extremity is continued by an arm, a fore-arm, and a hand, the latter being composed of two ranges of small bones, called the carpus, of another range called the metacarpus, and of the fingers, each of which consists of two or three bones, termed phalanges. With the exception of the cetacea, the first part of the posterior extre- mity, in all animals of this class, is fixed to the spine, forming a girdle or pelvis, which, in youth, consists of three pairs of bones — the ilium which is attached to the spine, the pubis which forms the anterior part of the girdle, and the ischium, the posterior. At the point of union of these 82 MAMMALIA. three bones is situated the cavity with which the thigh is articulated, to which, in its turn, is attached the leg, formed of two bones, the tibia and fibula ; this extremity is terminated by parts similar to those of the hand, i. e. by a tarsus, metatarsus, and toes. The head of the mammalia is always articulated by two condyles, with the atlas, the first vertebra of the neck. The brain is always composed of two hemispheres, united by a medul- lary layer, called the corpus callosum, containing the ventricles, and en- veloping fom pairs of tubercles, named the corpora striata, or striated bodies, the thalami nervorum opticorum, or beds of the optic nerves, and the nates and testes. Between the optic beds is a third ventricle, which communicates with a fourth under the cerebellum, the crura of which al- ways form a transverse prominence under the medulla oblongata , called the pons Varolii, or bridge of Yarolius. The eye, invariably lodged in its orbit, is protected by two lids and a vestige of a third, and has its crystalline fixed by the ciliary processes — its sclerotic is simply cellular. The ear always contains a cavity called the tympanum, or drum, which communicates with the mouth by the Eustachian tube; the cavity itself is closed externally by a membrane called the membrana tympani, and con- tains a chain of four little bones, named the incus or anvil, malleus or hammer, the os orbiculare or circular bone, and the stapes or stirrup ; a vestibule, on the entrance of which rests the stapes, and which communi- cates with three semicircular canals ; and, finally, a cochlea, which ter- minates by one canal in the vestibule, and by the other in the tympanum. Their cranium is subdivided into three portions ; the anterior is formed by the two frontal and ethmoidal bones, the middle by the two ossa parie- talia and the os ethmoides, and the posterior by the os occipitis. Between the ossa parietalia, the sphenoidalis and the os occipitis, are interposed the twoHemporal bones, part of which belong properly to the face. In the foetus, the occipital bone is divided into four parts : the sphenoi- dal into two halves, which are again subdivided into three pairs of lateral wings ; the temporal into three, one of which serves to complete the cra- nium, the second to close the labyrinth of the ear, the third to form the parietes of the tympanum, &c. These bony portions, still more numerous in the earliest period of the foetal existence, are united more or less promptly, according to the species, and the bones themselves finally be- come consolidated in the adult. Their face consists of the two maxillary bones, between which pass the nostrils ; the two intermaxillaries are situated before, and the two ossa palati behind them ; between these descends the vomer, a bony process of the os ethmoides; at the entrance of the nasal canal are placed She ossa MAMMALIA. 33 nasi ; to its external parietes adhere the inferior turbinated bones, the superior ones which occupy its upper and posterior portion belonging to the os ethmoides. The jugal or cheek bone unites the maxillary to the temporal bone on each side, and frequently to the os frontis ; finally, the os unguis, and pars plana of the ethmoid bone occupy the internal angle of the orbit, and sometimes a part of the cheek. In the embryo state these bones also are much more subdivided. Their tongue is always fleshy, connected with a bone called the hyoides, which is composed of several pieces, and suspended from the cranium by ligaments. Their lungs, two in number, divided into lobes, and composed of an infinitude of cells, are always inclosed, without any adhesion, in a cavity formed by the ribs and diaphragm and lined by the pleura ; the organ of voice is always at the upper extremity of the trachea; a fleshy curtain, called the velum palati, establishes a direct communication between then- larynx and nasal canal. Their residence on the surface of the earth rendering them less, exposed to the alternations of cold and heat, their tegument, the hair, is but mo- derately thick, and in such as inhabit warm climates, even that is rare. The cetacea, which live exclusively in water, are the only ones that are altogether deprived of it. The abdominal cavity is lined with a membrane called the peritoneum , and the intestinal canal is suspended to a fold of it called the mesentery , which contains numerous conglobate glands in which the lacteals ramify : another production of the peritoneum, styled the epiploon , hangs in front of and under the intestines. The urine, which is retained for a time in the bladder, finds an exit in both sexes, with very few exceptions, by orifices in the organs of gene- ration. In all the mammalia, generation is essentially viviparous ; that is, the foetus, directly after conception, descends into the uterus enveloped in its membranes, the exterior of which is called chorion and the interior amnios; it fixes itself to the parietes of this cavity by one plexus or more of ves- sels called the placenta, which establishes a communication between it and the mother, by which it receives its nourishment, and most probably its oxygenation ; notwithstanding which, the foetus of the mammalia, at an early period, has a vesicle analogous to that which contains the yolk in the ovipara, receiving in like manner vessels from the mesentery. It has also another external bladder named the allantoid , which communicates with the urinary one by a canal called the urachus. Conception always requires an effectual coitus, in which the semen masculinum is thrown into the uterus of the female. VOL. I. D 34- mammalia. The young are nourished for some time after birth by a fluid (milk) peculiar to animals of this class, which is produced by the mammae at the time of parturition, and continues to be so as long as is necessary. It is from the mammce that this class derives its name ; and being a character peculiar to it, they distinguish it better than any other that is external*. Division of the Mammalia into Orders. The variable characters which form essential differences among the Mammalia are taken from the organs of touch, on which depends their degree of ability or address, and from the organs of manducation, which determine the nature of their aliment, and are all closely connected, not only with every thing relative to the function of digestion, but also with a multitude of other differences relating even to their intelligence. The degree of perfection of the organs of touch is estimated by the numb.er and the pliability of the fingers, and from the greater or less ex- tent to which their extremities are enveloped by the nail or the hoof. A hoof, which completely envelopes the end of the toe, blunts its sensi- bility, and renders the foot incapable of seizing. The opposite extreme is when a nail, formed of one single lamina, covers only one of the faces of the extremity of the finger, leaving the other pos- sessed of all its delicacy. The nature of the food is known by the grinders, to the form, of which the articulation of the jaws universally corresponds. To cut flesh, grinders are required as trenchant as a saw, and jaws fitted like scissars, having no other motion than a vertical one. For bruising roots or grains, flat-crowned grinders are necessary, and jaws that have a lateral motion; in order that inequalities may always exist on the crown of these teeth, it is also requisite that their substance be composed of parts of unequal hardness, so that some may wear away faster than others. Hoofed animals are all necessarily herbivorous, and have flat-crowned grinders, inasmuch as their feet preclude the possibility of their seizing a living prey. Animals with unguiculated fingers were susceptible of more variety; their food is of all kinds ; and, independently of the form of their grinders, they differ greatly from each other in the pliability and delicacy of their fingers. There is one character with respect to this, which has immense influence on their dexterity, and greatly multiplies its powers ; it is the faculty of opposing the thumb to the finger for the purpose of seizing mi- * We shall find, however, in the sequel some doubts on this subject, arising from certain points in the family of the Monotremata. MAMMALIA. nute objects, constituting wliat is properly called a hand; a faculty which is carried to its highest perfection in man, in whom the whole anterior ex- tremity is free and capable of prehension. These various combinations, which strictly determine the nature of the different Mammalia, have given rise to the following orders : — Among the unguiculated animals, the first is Man , who, in addition to privileges of other descriptions, possesses hands at the anterior extremi- ties only, the posterior being designed to support him in an erect position. In the order next to man, that of the quadrumana, we find hands at the four extremities. In another order, that of the carnaria, the thumb is not free, and cannot be opposed to the anterior extremities. Each of these orders has the three sorts of teeth, grinders, canini, and incisors or cutting teeth. In a fourth order, that of the rodentia, the toes differ but little from those of the Carnaria, but there are no canine teeth, and the incisors are placed in front of the mouth, and adapted to a very peculiar sort of man- ducation. Then come those animals whose toes are much cramped, and deeply sunk in large nails, which are generally curved ; they have no incisors, and in some the canines disappear, while others have none of any descrip- tion. We comprise them all under the title of the Edentata. This distribution of the unguiculated animals would be perfect, and form a very regular series, were it not that New Holland has lately fur- nished us with a little collateral one, consisting of animals with pouches , the different genera of which are connected by a general similarity of or- ganization ; some of them, however, in the teeth and nature of their diet corresponding to the Carnaria, others to the Rodentia, and a third to the Edentata. The hoofed animals are less numerous, and have likewise fewer irregu- larities. The rttminantia, by their cloven foot, the absence of true incisors in their upper jaw, and their four stomachs, form an order that is very distinct. The remaining hoofed animals may all be united in a single order, which I shall call paciiydermata or jumenta, the elephant excepted, which might constitute a separate one, and which is remotely connected with that of the Rodentia. . In the last place, we find those of the Mammalia which have no poste- rior extremities, whose piscatory form and aquatic mode of life would in- duce us to form them into a particular class, were it not that in every thing else their economy is similar to that in which we leave them. S6 MAMMALIA. These are the hot-blooded fishes of the ancients, or the cetacea, which, uniting to the vigour of the other Mammalia the advantage of being sus- tained by the watery element, present to our wondering sight the most gigantic of animals. ORDER I. BIMANA. Man forms but one genus, and that genus the only one of its order. As his history is the more directly interesting to ourselves, and forms the point of comparison to which we refer that of other animals, we will speak of it more in detail. We will rapidly sketch every thing that is peculiar in each of his -or- ganic systems, amidst all that he shares in common with other Mammalia; we will examine the advantages he derives from these peculiarities over other species ; we will describe the principal varieties of his race and their distinguishing characters, and finally point out the natural order in which his individual and social faculties are developed. Peculiar Conformation of Man. The foot of Man is very different from that of the Monkey ; it is large ; the leg bears vertically upon it ; the heel is expanded beneath ; the toes are shorty and but slightly flexible ; the great toe, longer and larger than the rest, is placed on the same line with, and cannot be opposed to them. This foot, then, is peculiarly well adapted to support the hody ; but cannot be used for seizing or climbing, and as the hands are not calculated for walking, Man is the only true bimanous and biped animal. The whole body of Man is arranged with a view to a vertical position. His feet, as just mentioned, furnish him with a base more extensive than that of any other of the Mammalia. The muscles which extend the foot and thigh are more vigorous, whence proceeds the projection of the calf and buttock ; the flexors of the leg are inserted higher up, which allows full extension of the knee, and renders the calf more apparent. The pelvis is wider, hence a greater separation of the thighs and feet, and that pyramidal form of the body so favourable to equilibrium. The necks of the thigh bones form an angle with the body of the bone, which increases still more the separation of the feet, and augments the basis of the body. Finally, the head in this vertical position is in equilibrium on the body, because its articulation is exactly under the middle of its mass. Were he to desire it, Man could not, with convenience, walk on all fours ; his short and nearly inflexible foot, and his long thigh, would bring the knee to the ground ; his widely separated shoulders and his arms, too far extended from the median line, would ill support the upper portion of BIM ANA. 37 liis body. Tlie great indented muscle, which, in quadrupeds, suspends, as in a girth, the body between the scapulae, is smaller in Man than in any one among them. The head is also heavier, both from the magnitude of the brain and the smallness of the sinuses or cavities of the bones ; and yet the means of supporting it are weaker, for he has neither cervical ligament, nor are his vertebrae so arranged as to prevent their flexure forwards ; the result of this would be, that he could only keep his head in the same line with the spine, and then his eyes and mouth being directed towards the earth, he could not see before him; — in the erect position, on the con- trary, the arrangement of these organs is every way perfect. The arteries which are sent to his brain, not being subdivided as in many quadrupeds, and the blood requisite for so voluminous an organ being carried into it with too much violence, frequent apoplexies would be the consequence of a horizontal position. Man, then, is formed for an erect position only. He thus preserves the entire use of his hands for the arts, while his organs of sense are most favourably situated for observation. These hands, which derive such advantages from their liberty, receive as many more from their structure. The thumb, longer in proportion than that of the Monkey, increases its facility of seizing small objects. All the fingers, the annularis excepted, have separate movements, a fa- culty possessed by no other animal, not even by the monkey. The nail, covering one side only of the extremity of the finger, acts as a support to the touch, without depriving it of an atom of its delicacy. The arms, to which these hands are attached, are strongly and firmly connected by the large scapula, the strong clavicle, &c. Man, so highly favoured as to dexterity, is not at all so with respect to force. His swiftness in running is greatly inferior to that of other animals of his size. Having neither projecting jaws, nor salient canine teeth, nor claws, he is destitute of offensive weapons; and the sides and upper parts of his body being naked, unprovided even with hair, he is absolutely with- out defensive ones. Of all animals, he is also the longest in attaining the power necessary to provide for himself. This very weakness, however, is but one advantage more — it compels him to have recourse to that intelligence within, for which he is so emi- nently conspicuous. No quadruped approaches him in the magnitude and convolutions of tlie hemispheres of the brain, that is, in the part of this organ which is the principal instrument of the intellectual operations. The posterior portion of the same organ extends backwards, so as to form a second covering to the cerebellum; the very form of his cranium announces this magnitude of the brain, while the smallness of his face shews how slightly that por- tion of the nervous system which influences the external senses predomi- nates in him. These external sensations, moderate as they all are in Man, are never- theless extremely delicate and well balanced. His two eyes are directed forwards ; he does not see on two sides at once, like many quadrupeds ; which produces more unity in the result of his sight, and concentrates his attention more closely on sensations of this kind. The ball and iris of his eye vary but little ; this restrains the ac- tivity of his sight to a limited distance, and a determined degree of light. 38 MAMMALIA. His external ear, possessing but little mobility or extent, does not increase the intensity of sounds ; and yet, of all animals, he best distinguishes the various degrees of intonation. His nostrils, more complicated than those of the monkey, are less so than those of all other genera ; and yet he ap- pears to be the only animal whose sense of smell is sufficiently delicate to lie affected by unpleasant odours. Delicacy of smell must have some in- fluence on that of taste ; and, independently of this, Man must have some advantage in this respect over other animals, those, at least, whose tongues are covered with scales. Lastly, the nicety of his tact results both from the delicacy of his teguments and the absence of all insensible parts, as well as from the form of his hand, which is better adapted than that of any other animal for suiting itself to every little superficial inequality. Man is pre-eminently distinguished in the organ of his voice ; of all the Mammalia, he alone possesses the faculty of articulating sounds, its pro- bable causes being the form of his mouth and the great mobility of his lips. From this results his most invaluable mode of communication ; for, of all the signs which can be conveniently employed for the transmission of ideas, variations of sound are those which can be perceived at the greatest dis- tance, and are the most extensive in their sphere of operation. The whole of his structure, even to the heart and great vessels, appears to have been framed with a view to a vertical position. The heart is placed obliquely on the diaphragm, and its point inclines to the left, thereby occasioning a distribution of the aorta, differing from that of most quad- rupeds. The natural food of man, judging from his structure, appears to consist of the fruits, roots, and other succulent parts of vegetables : his hands of- fer him every facility for gathering them ; his short, and but moderately strong jaws on the one hand, and his canini being equal in length to the remaining teeth, and his tubercular molares on the other, would allow him neither to feed on grass nor to devour flesh, were these aliments not pre- viously prepared by cooking. Once, however, possessed of fire, and those arts by which he is aided in seizing animals or killing them at a distance, every living being was rendered subservient to his nourishment, thereby giving him the means of an infinite multiplication of his species. His organs of digestion are in conformity with those of manducation ; his stomach is simple, his intestinal canal of moderate length, the great in- testines well marked, his caecum short and thick and augmented by a small appendage, and his liver divided only into two large lobes and one small one ; his epiploon hangs in front of the intestines, and extends into the pelvis. To complete the hasty sketch of the anatomical structure of Man requisite for this introduction, we will add, that he has thirty-two vertebrae, of which seven belong to the neck, twelve to the back, five to the loins, five to the sacrum, and three to the coccyx. Seven pairs of his ribs are united with the sternum by elongated cartilages, and are called true ribs ; the five fol- lowing pairs are denominated false ones. His adult cranium is formed of eight bones; an occipitalis, two ossa temporis, two parietalia, and the frontal, ethmoidal and sphenoidal bones. The bones of his face are four- teen in number, two maxillaries, two ossa mala*, each of which joins the temporal to the maxillary bone of its own side by a kind of handle called the zygomatic arch ; two nasal bones, two ossa palati behind the palate, a vomer between the nostrils, two turbinated bones of the nose in the nos- BIMANA. 39 trils, two lachrymals (unguis) in the internal angles of the orbits and the single bone of the lower jaw. Each jaw has sixteen teeth; four cutting incisors in the middle, two pointed canines at the corners, and ten tuber - culated molares, five on each side. At the extremity of the spine of his scapula, is a tuberosity called the acromion, to which the clavicle is at- tached, and over its articulation is a point called the coracoid process, with which certain muscles are connected. The radius revolves upon the ulna, owing to the mode of its articulation with the humerus. The carpus has eight bones, four in each range; the tarsus has seven; those of the re- maining parts of the hand and. foot may be easily counted by the number of fingers and toes. Enjoying uniform and regular supplies of nourishment, the fruit of his industry, Man is at all times inclined to the “plaisirs d’amour,” without ever experiencing that irresistible and violent impetus which marks the passion in quadrupeds. His organ of generation is not upheld by a bony axis; the prepuce does not tie it down to the abdomen, and it hangs loosely in front of the pubis. Numerous and large veins which effect a rapid transfer of the blood of his testes to the general circulation, appear to contribute to the moderation of his desires. The uterus of woman is a simple oval cavity; her mammae, only two in number, are placed upon her breast, and correspond with the facility she possesses of supporting her child upon her arm. Physical and Moral Dev elopement of Man. The term of gestation in the human species is nine months ; and but one child is usually produced at a birth, as in five hundred cases of partu- rition there is but one of twins ; more than the latter is extremely rare The foetus, a month old, is generally about one inch in height ; when two months, it is two inches and a half; when three, five inches; in the fifth month, it is six or seven inches; in the seventh, it is eleven inches; in the eighth, fourteen, and in the ninth, eighteen inches. Those which are born prior to the seventh month usually die. The first or milk teeth begin to appear in a few months, commencing with the incisors. The number increases in two years to twenty, which, about the seventh year, are successively shed to make room for others. Of the twelve posterior molares which are permanent, there are four which make their appearance at four years and a half, and four at nine ; the last four are frequently not cut until the twentieth year. The growth of the foetus is proportionably increased as it approaches the time of birth — that of the child, on the contrary, is always less and less. It has more than the fourth of its height when born ; it attains the half of it at two years and a half, and the three-fourths at nine or ten years ; its growth is completed about the eighteenth year. Man rarely exceeds the height of six feet, and as rarely remains under five. Woman is usually some inches shorter. Puberty is announced by external symptoms, from the tenth to the twelfth year in girls, and from the twelfth to the sixteenth in boys ; it ar- rives sooner in warm climates ; and neither sex (very rarely at least) is productive before or after that manifestation. Scarcely has the body gained the full period of its growth in height, before it begins to increase in bulk ; fat accumulates in the cellular tissue, 40 MAMMALIA. the different vessels become gradually obstructed, the solids become rigid, and, after a life more or less long, more or less agitated, more or less painful, old age arrives with decrepitude, decay, and death. Man rarely lives beyond a hundred years, and most of the species, either from disease, accident, or old age, perish long before that term. The child needs the assistance of its mother much longer than her milk ; from this it obtains an education both moral and physical, and a mutual attachment is created that is fervent and durable. The nearly equal number of the two sexes, the difficulty of supporting more than one wife, when wealth does not supply the want of power, all go to prove that monogamy is the mode of union most natural to our species; and as, wherever this kind of tie exists, the father participates in the education of his offspring, the length of time required for that education allows the birth of others — hence the natural permanence of the conjugal state. From the long period of infantile weakness springs domestic subordination, and the order of society in general, as the young people which compose the new families continue to preserve with their parents those tender re- lations to which they have so long been accustomed. This disposition to mutual assistance multiplies to an almost unlimited extent those advan- tages previously derived by insulated man from his intelligence; it has assisted him to tame or repulse other animals, to defend himself from the effects of climate, and thus enabled him to cover the earth with his species. In other respects, man appears to possess nothing resembling instinct, no regular habit of industry produced by innate ideas ; his knowledge is the result of his sensations and of his observation, or of those of his prede- cessors. Transmitted by speech, increased by meditation, and applied to his necessities and his enjoyments, they have originated all the arts of life. Language and letters, by preserving acquired knowledge, are a source of indefinite perfection to his species. It is thus he has acquired ideas, and made all nature contribute to his wants. There are very different degrees of developement, however, in man. The first hordes, compelled to live by fishing and hunting, or on wild fruits, and being obliged to devote all their time to search for the means of subsistence, and not being able to multiply greatly, because that would have destroyed the game, advanced but slowly. Their arts were limited to the construction of huts and canoes, to covering themselves with skins, and the fabrication of arrows and nets. They observed such stars only as directed them in their journeys, and some few natural objects whose pro- perties were of use to them. They domesticated the dog, simply because he had a natural inclination for their own kind of life. When they had succeeded in taming the herbivorous animals, they found in the possession of numerous flocks a never failing source of subsistence, and also some leisure, which they employed in extending the sphere of their acquire- ments. Some industry was then employed in the construction of dwell- ings and the making of clothes : the idea of property was admitted, and consequently that of barter, as well as wealth and difference of conditions, those fruitful sources of the noblest emulation and the vilest passions : but the necessity of searching for fresh pastures, and of obeying the changes of the seasons, still doomed them to a wandering life, and limited their improvement to a very narrow sphere. BIM AN A. 41 The multiplication of the human species, and its improvement in the arts and sciences, have only been carried to a high degree since the inven- tion of agriculture and the division of the soil into hereditary possessions. By means of agriculture, the manual labour of a portion of society is ade- quate to the maintenance of the whole, and allows the remainder time for less necessary occupations, at the same time that the hope of acquiring, by industry, a comfortable existence for self and posterity, has given a new spring to emulation. The discovery of a representative of property, or a circulating medium, by facilitating exchanges and rendering fortunes more independent and susceptible of being increased, has carried this emulation to its highest degree ; but, by a necessary consequence, it has also equally increased the vices of effeminacy and the furies of ambition. The natural propensity to reduce every thing to general principles, and to search for the causes of every phenomenon, has produced reflecting men, in every stage of society, who have added new ideas to those already obtained, nearly all of whom, while knowledge was confined to the few, endeavoured to convert their intellectual superiority into the means of do- mination, by exaggerating their own merit, and disguising the poverty of their knowledge by the propagation of superstitious ideas. An evil still more irremediable is the abuse of physical power: now that man only can injure man, he is continually seeking to do so, and is the only animal upon earth that is for ever at war with his own species. Savages fight for a forest, and herdsmen for a pasture, and, as often as they can, break in upon the cultivators of the earth to rob them of the fruits of their long and painful labours. Even civilized nations, far from being contented with their blessings, pour out each other’s blood for the prero- gatives of pride, or the monopoly of trade. Hence, the necessity for go- vernments to direct the national wars, and to repress or reduce to regular forms the quarrels of individuals. The social condition of man has been restrained, or advanced by circum- stances more or less favourable. The glacial climates of the north of both continents, and the impenetra- ble forests of America, are still inhabited by the savage hunter or fisher- man. The immense sandy and salt plains of Central Asia and Africa ai»e covered with a pastoral people and innumerable herds. These half civi- lized hordes assemble at the call of every enthusiastic chief, and rush like a torrent on the cultivated countries that surround them, in which they es- tablish themselves, but to be weakened by luxury, and in their turn to be- come the prey of others. This is the true cause of that despotism which has always crushed and destroyed the industry of Persia, India, and China. Mild climates, soils naturally irrigated and rich in vegetables, are the natural cradles of agriculture and civilization ; and when so situated as to be sheltered from the incursions of barbarians, every species of talent is excited ; such were (the first in Europe) Greece and Italy, and such is, at present, nearly all that happy portion of the earth. There, are, however, certain intrinsic causes which seem to arrest the progress of particular races, although situated amidst the most favourable circumstances. 4 2 MAMMALIA, Varieties of the Human Species (a). Although the promiscuous intercourse of the human species, which pro- duces individuals capable of propagation, would seem to demonstrate its (a) Notwithstanding the high character of Cuvier, as a founder of classes, yet the arrangement established by Blumenhach of the varieties of the human species has been universally adopted. In this classification the varieties are five, viz. — I. The Caucasian , which comprehends the ancient and modern inhabitants of Europe, the Western Asiatics, or those of this side of the Caspian Sea, and of the rivers Ohi and the Ganges, together with the Northern Africans. The characters of this race are as follows: — The head is nearly the figure of a globe; the forehead is high and expanded; the cheek hones are without prominences; the nose is narrow and slightly aquiline; the face is oval and straight; the mouth small, with lips slightly everted; the skin is white, and the cheeks florid; the hair is long, soft, and shining, and varies in colour, from a nut-brown to the deepest black. — There are thirty- eight crania of this variety in the Hunterian Museum, London College of Surgeons. (See Plate I. Mammalia, Fig. 1. The portrait of Jusuf Aguiah Efendi, a Turk, and once Ambassador from the Sublime Porte at the Court of London). II. The Mongolian, commonly called the Tartarian, takes in the Finnish tribes in- habiting the colder parts of the north of Europe, such as the Laplanders and Esqui- maux, and also the Asiatics not included in the Caucasian variety, so that it com- prehends the Chinese, but not the Malays. The head approximates to a quadrilateral figure; the face broad and flattened, so that the parts appear to run into each other; the nose is small and flat, and the space between the eyes flat and broad; the cheek- bones are rounded and projecting; the aperture made by the eye-lids is narrow, and its line extends towards the temples, the internal angle of the eye being depressed towards the nose, and the upper eye-lid being at that angle continued into the lower one by a rounded sweep; the skin is pale olive, and the hair is thin, black, stiff*, and straight. — There are nine crania of this variety in the Hunterian Museum. (See Plate I. Mammalia, Fig. 2. The portrait of Feodor Iwanowitsch, a Cal- muck, who was sent, when young, by the Empress of Russia to the Hereditary Princess of Baden; was educated at Carlsruhe, and became a famous engraver at Rome). III. The ^Ethiopian, consists of all the Africans not included in the Caucasian divi- sion, and these partake more or less of the negro character. The front of the head is compressed laterally, and looks as if the forehead were removed, being, in this respect, a perfect contrast with the globular form of the head of the Caucasian va- riety. The entire cranium is contracted anteriorly, its cavity is considerably les- sened; the foramen magnum, and the condyles at its circumference, are placed farther hack towards the occipital region ; there is great developement of the face, and great prominence of the jaws, particularly of their alveolar margins and teeth, the upper incisors are oblique; the chin recedes, and the zygomatic arch projects to- wards the front; the skin is brown, black, and sometimes yellow, and the hair is deep black, crisp, and curly. — There are ten crania of this variety in the Hunterian Museum. (See Plate I. Mammalia, Fig. 3. The portrait of J. J. E. Capitein. a negro, who received holy orders in Holland). IV. The American, includes all the inhabitants of the vast continent of North and South America, excepting those of the northern part of the continent, and some of the islands, particularly the Carihhee. The cheeks are broad, hut the malar hones are more rounded and arched than in the Mongolian race; the forehead is small and low ; the orbits of the eye are unusually deep, and the nasal cavity is very large. The Carihs were in the habit of lowering the forehead by employing artificial pres- sure on the head in early infancy; hence, in this community, the characteristic feature of the American variety, the low forehead, is much more strikingly marked than in any other class of Americans. — There are five crania of this variety in the Hunterian Museum. (See Plate I. Mammalia, Fig. 4. The portrait of Thay Endaneega, a chief of the Mohawks, or Six Nations). V. The Malay, embraces the whole of the natives of the numerous Asiatic islands, and of those of the Pacific Ocean, New Zealand, New Holland, &c. Their head is BIMAN A. 43 unity, certain hereditary peculiarities of conformation are observed, which constitute what are termed races. Three of them in particular appear very distinct — the Caucasian or white, the Mongolian or yellowr, and the Ethiopian or negro. The Caucasian, to which we belong, is distinguished by the beauty of the oval formed by his head, varying in complexion and the colour of the hair. To this variety, the most highly civilized nations, and those which hare generally held all others in subjection, are indebted for their origin. The Mongolian is known by his high cheek bones, flat visage, narrow and oblique eyes, straight black hair, scanty beard and olive complexion. Great empires have been established by this race in China and Japan, and their conquests been extended to this side of the Great Desert. In civi- lization, however, it has always remained stationary. The Negro race is confined to the south of mount Atlas ; it is marked by a black complexion, crisped or woolly hair, compressed cranium, and a flat nose. The projection of the lower parts of the face, and the thick lips, evidently approximate it to the monkey tribe : the hordes of which it consists have always remained in the most complete state of utter bar- barism. The race from which we are descended has been called Caucasian , be- cause tradition and the filiation of nations seem to refer its origin to that group of mountains situated between the Caspian and Black seas, whence, as from a centre, it has been extended like the radii of a circle. Various nations in the vicinity of Caucasus, the Georgians and Circassians, are still considered the handsomest on earth. The principal ramifications of this race may be distinguished by the analogies of language. The Ar- menian or Syrian branch, stretching to the south, produced the Assyrians, the Chaldeans, the hitherto untameable Arabs, who, after Mahomet, were near becoming masters of the world; the Phoenicians, Jews, and Abyssini- ans, which were Arabian colonies ; and most probably the Egyptians. It is from this branch, always inclined to mysticism, that have sprung the most widely extended forms of religion — the arts and literature have some- times flourished among its nations, but always enveloped in a strange dis- guise and figurative style. The Indian, German, and Pelasgic branch is much more extended, and was much earlier divided : notwithstanding which, the most numerous affi- nities may be observed between its four principal languages — the Sanscrit, the present sacred language of the Hindoos, and the parent of the greater number of the dialects of Hindostan ; the ancient language of the Pelasgi, common mother of the Greek, Latin, many tongues that are extinct, and of all those of the south of Europe; the Gothic or Teutonic, from which are derived the languages of the north and north-west of Europe, such as the German, Dutch, English, Danish, Swedish, and other dialects; and moderately narrowed; the forehead is slightly arched; the face is large, and all its parts are fully developed; the jaws are more or less prominent; the skin is tawny, or clear mahogany or chesnut brown; the hair is black, soft, and curled. — There are thirty-four crania of this variety in the Hunterian Museum. (See Plate I. Mam- malia, Fig. 5. The portrait of Omai, a native of Ulieten, one of the Society Islands, brought to England in 1 773, and carried back by Cook). — Eng. Ed. 41- mammalia. iinally, the Sclavonian, from which spring those of the north-east, the Rus- sian, Polish, Bohemian, &c. It is by this great and venerable branch of the Caucasian stock, that philosophy, the arts, and the sciences have been carried to the greatest perfection, and remained in the keeping of the nations which compose it for more than three thousand years. It was preceded in Europe by the Celts, who came from the north, wdiose tribes, once very numerous, are now confined to its most eastern extremity, and by the Cantabrians, who passed from Africa into Spain, now confounded with the many nations whose posterity have intermingled in that peninsula. The ancient Persians originate from the same source as the Indians, and their descendants to the present hour bear great marks of resemblance to the people of Europe. The predatory tribes of the Scythian and Tartar branch, extending at first to the north and north-east, always wandering over the immense plains of those countries, returned only to devastate the happier abodes of their more civilized brethren. The Scythians, who, at so remote a period, made irruptions into upper Asia ; the Parthians, who there destroyed the Greek and Roman domination; the Turks, who there subverted that of the Arabs, and subjugated in Europe the unfortunate remnant of the Grecian people, all swarmed from this prolific branch. The Finlanders and Hun- garians are tribes of the same division, which have strayed among the Sclavonic and Teutonic nations. Their original country, to the north and north-east of the Caspian sea still contains inhabitants who have the same origin, and speak similar languages, but mingled with other petty nations, variously descended, and of different languages. The Tartars remained unmixed longer than the others in the country included between the mouth of the Danube to beyond the Irtisch, from which they so long menaced Russia, and where they have finally been subjugated by her. The Mon- goles, however, have mingled their blood with that of those they con- quered, many traces of which may still be found among the inhabitants of lesser Tartary. It is to the east of this Tartar branch of the Caucasian race that the Mongolian race begins, whence it extends to the eastern ocean. Its branches, the Calmucs, &c., still wandering shepherds, are constantly tra- versing the desert. Thrice did their ancestors, under Attila, Genghis, and Tamerlane, spread far the terror of their name. The Chinese are the earliest and most civilized branch, not only of this race, to which they belong, but of all the nations upon earth. A third branch, the Mant- chures, recently conquered and still govern China. The Japanese, Co- reans, and nearly all the hordes which extend to the north-east of Siberia, subject to Russia, are also to be considered, in a great measure, as ori- ginating from this race ; and such also is esteemed the fact, with regard to the original inhabitants of various islands of that Archipelago. With the exception of a few Chinese literati, the different nations of the Mongoles are universally addicted to Buddism, or the religion of Fo. The origin of this great race appears to have been in the mountains of Atlai, but it is impossible to trace the filiation of its different branches with the same certainty as we have done those of the Caucasian. The history of these wandering nations is as fugitive as their establishments ; B1MANA. 45 and that of the Chinese, confined exclusively to their own empire, gives us nothing satisfactory with respect to their neighbours. The affinities of their languages are also too little known to direct us in this labyrinth. The languages of the north of the Peninsula beyond the Ganges, as well as that of Thibet, are somewhat allied to the Chinese, at least in their monosyllabic structure, and the people who speak them have features somewhat resembling other Mongoles. The south of this Peninsula, how- ever, is inhabited by Malays, whose forms approximate them much nearer to the Indians, whose race and language are extended over all the coasts of the islands of the Indian Archipelago. The innumerable little islands of the southern ocean are also peopled by a handsome race, nearly allied to the Indians, whose language is very similar to the Malay ; in the inte- rior of the largest of these islands, particularly in the wilder portions of it, is another race of men with black complexions, crisped hair, and negro faces, called Alfourous. On the coast of New Guinea, and in the neigh- bouring islands, we find other negroes, nearly similar to those of the east- ern coast of Africa, named Papuas * ; to the latter, are generally referred the people of Van-Diemen’s land, and those of New Holland to the Alfourous. These Malays, and these Papuas are not easily referable to either of the three great races of which we have been speaking ; but, can the former be clearly distinguished from their neighbours, the Caucasian Hindoos and the Mongolian Chinese ? As for us, we confess we cannot discover any sufficient characteristics in them for that purpose. Are the Papuas ne- groes, which may formerly have strayed into the Indian ocean? We pos- sess neither figures nor descriptions sufficiently precise to enable us to answer this question. The northern inhabitants of both continents, the Samoiedes, the Lap- landers, and the Esquimaux, spring, according to some, from the Mongo- lian race, while others assert that they are mere degenerate offsets from the Scythian and Tartar branch of the Caucasian stock. We have not yet been able to refer the Americans to any of the races of the eastern continent ; still, they have no precise or constant character which can entitle them to be considered as a particular one. Their cop- per-coloured complexion is not sufficient ; their generally black hair and scanty beard would induce us to refer them to the Mongoles, if their de- fined features, projecting nose, large and open eye, did not oppose such a theory, and correspond with the features of the European. Their lan- guages are as numberless as their tribes, and no demonstrative analogy has as yet been obtained, either with each other, or with those of the old world •j'. * With respect to the various nations of the Indian and Pacific oceans, see the dissertation of Messrs. Lesson and Garnot in the Zoologie du Voyage de la Coquille, p. 1 — 113. For the languages of the Asiatics and their affinities, consult the Asia Polyglotta of M.

Independently of the anatomical details which, distinguish it from man, and which have been given, this family differs from our species in a very remarkable way. All the animals belonging to it have the toes of the hind feet free and opposable to the others, and the toes are all as long and flexible as fingers. In consequence of this, the whole species climb trees with the greatest facility, while it is only with pain and difficulty they can stand and walk upright; their foot then resting on its outer edge only, and their narrow pelvis being unfavourable to an equilibrium. They all have intestines very similar to those of man; the e^es directed forwards, the mammas on the breast, the penis pendent. The brain has three lobes on each side, the posterior of which covers the cerebellum, and the tem- poral fossae are separated from the orbits by a bony partition. In every thing else, however, they gradually lessen in resemblance to him, by as- suming a muzzle more and more elongated, and a tail and a gait more like that of quadrupeds. Notwithstanding this, the freedom of their arms and the complication of their hands allow them all to perform many of the ac- tions of man as well as to imitate his gestures. They have long been divided into two genera, the Monkeys and the Lemurs , which, by the multiplication of secondary forms, have now be- come two small families, between which we must place a third genus, that of the Ouistitis , as it is not conveniently referable to the one or the other. SiMrA, Lin . The monkeys are all quadrumana, which have four straight incisors in each jaw, and flat nails on all the extremities; two characters which ap- proximate them more nearly to man than the subsequent genera ; their molares have also blunt tubercles like ours, and their food consists chiefly of fruits. Their canine teeth, however, being longer than the rest, sup- ply them with a weapon we do not possess, and which require a hollow in the opposite jaw, to receive them when the mouth is closed. They may be divided, from the number of their molar teeth, into two prin- cipal subgenera, which are again subdivided into numerous groups*. The * Buffon subdivided the monkeys into five tribes : the true monkeys, without tails ; the baboons, with short tails; the guenons, with long tails and callous buttocks; the sapajous, with long prehensile tails and no callus ; the sagouins, with long tails, not prehensile and without callus. Erxleben, adopting this division, translated these names by simia, papio, cercopitliecus, cebus, and callithrix. Thus it is, that the names QUADRUMANA 47 Monkeys, properly so called , Or those of the eastern continent, have the same number of grinders as Man, but otherwise differing from each other by characters, which have formed the grounds of the following subdivisions : — The Simia, Erxl. — Pithecus, Geoffr. The Ourangs* * are the only monkeys of the ancient continent which have no callus on the buttock ; their hyoid bone, liver, and caecum resem- ble those of Man. Their nose is not prominent, they have no cheek- pouches, nor a vestige of a tail. Some of them have arms long enough to reach the ground when standing — their legs, on the contrary, are very short. S. satyrus, L. ; Audeb., pi. 2; Fr. Cuv. pi. 2. (The Ourang- Outang'i'.) Of all animals, this Ourang is considered as approach- ing most nearly to Man in the form of his head, height of forehead, and volume of brain ; but the exaggerated description of some au- thors respecting this resemblance, are partly to be attributed to the cebus and callithrix , by which the antients designated monkeys of Africa and India, have been transferred to those of America. The genus Papio, founded solely on the shortness of the tail, could not be retained, as it violated natural affinities, and all the others required subdividing. It was also necessary to abolish the genus Ouistitis, which was comprised in that of the Sagouins, but which does not altogether corres- pond with the common characters of the other monkeys. * Orang (a) is a Malay word signifying reasonable being, which is applied to man, the ourang- outang, and the elephant. Outang means wild, or of the woods; hence Wild Man of the Woods. f The only good figure of the Ourang- Outang we had for a long time was that of Vosmaer, taken from a living specimen at the Hague. That of Buffon, Suppl. VIII. pi. 1, is ever}' way erroneous; that of Allamand (Buff. d’Holl. XV. pi. 11,) is some- what better — it was copied in Schreber, pi. 2, B. That of Camper, copied ib., pi. 2, C., is tolerably exact, but is easily discovered to have been taken from the dead body. Bontius, Med. Ind. 84, gives a completely ideal one, although Linnaeus took it for the type of his Troglodyte (Amaen. Ac. VI, pi. 1, § 1). There are some good ones in Griffith, and in Krusenstern’s Voyage, pi. 94 and 95, but all of them from young subjects. fldT (a) The species which constitute the sub-genus “Orangs” of Cuvier, are sepa- rated into two sub-genera by Geoffroy, who makes the Simia Satyrus the type of his first 8ub-genus, Pithecus; and Simia Troglodytes that of his second sub-genus, Troglo- dytes. Besides the distinctions between these two species, described by both Cuvier and Geoffroy, there are two others, which may be easily ascertained on an examina- tion of the skeletons of both. In the Pithecus, or Simia Satyrus, the ribs are of the same number as those of the human body, namely, twelve on each side. But, in the Simia Troglodytes, the ribs on each side are thirteen, the extra pair being arti- culated with the first lumbar vertebra on each side. Between the sternum (breast- bone) of the two apes, a striking difference also prevails. That of the Simia Satyrus is much broader in proportion to its length; and the second, third, fourth, and fifth bones which compose it, are divided longitudinally into two parallel rows, the sepa- rate portions alternating with each other, leaving an indented suture between them, which is peculiarly manifest in the young animal. Now, in the Simia Troglodytes, the sternum is simply divided, in the ordinary way, into five separate portions which arc entire; it is altogether much narrower or more compressed laterally than it is in the former species.

Ed. 48 MAMMALIA. fact of their being drawn from young individuals only ; and there is every reason to believe, that, with age, their muzzle becomes much more prominent. The body is covered with coarse red hair, the face blueish, and the hinder thumbs very short compared with the toes. His lips are susceptible of a singular elongation, and possess great mobility. His history has been much disfigured by mingling it with that of the other great monkeys, that of the Chimpanse, in particu- lar. After a strict and critical examination, I have ascertained that the Ourang-Outang inhabits the most eastern countries only, such as Malabar, Cochin China, and particularly the great island of Borneo, whence he has been occasionally brought to Europe by the way of Java. When young, and such as he appears to us in his captivity, he is a mild and gentle animal, easily rendered tame and affection- ate, which is enabled by his conformation to imitate many of our ac- tions, but whose intelligence does not appear to be as great as is reported, not much surpassing even that of the Dog. Camper dis- covered, and has tvell described two membranous sacs in this animal which communicate with the glottis, that produce a hoarseness of his voice — he was mistaken, however, in imagining that the nails are always wanting on his hinder thumbs. There is a monkey in Borneo, hitherto known only by his skeleton, called the Pongo *, which so closely resembles the Ourang-Outang in the proportions of all his parts, and by the arrangement of the fora- „ mina and sutures of the head, that, notwithstanding the great pro- minence of the muzzle, the smallness of the cranium, and the height of the branches of the lower jaw, we are tempted to consider him an adult — if not of the species of the Ourang-Outang, at least of one very nearly allied to it. The length of the arms, that of the apo- physes of the cervical vertebrae, and the tuberosity of his calcaneum, may enable him to assume the vertical position, and walk upon two feet. He is the largest monkey known, and in size is nearly equal to Man. Mr. J. Harwood, in the Trans. Lin. Soc. XV. p. 471, describes the feet of an ourang, fifteen English inches in length. This an- nounces a very great stature in the animal to which they belonged, and would have led him to the belief that the Pongo is the adult Ourang-Outang, were it not that the skeleton of the Pongo in the College of Surgeons, at London, has one lumbar vertebra more than those of the Ourangs. This, however, is no objection — the same variation is frequently observed in the human subject. The arms of the remaining Ourangs reach only to the knee. They * Audeb. Singes, pi. anat. 2. This name of Pongo , a corruption of Boggo, which is given in Africa to the Chimpanse , or to the Mandrill, was applied by Buffon to a pretended large species of Ourang-Outang — the mere imaginary product of his com- binations. Wurmb, a naturalist of Batavia, has transferred it to this animal, which he was the first to describe, and of which Buffon never had any idea. See Mem. of the Soc. of Batavia, vol. ii. p. 245. The thought, that it might be an adult Ourang, struck me on examining the head of an ordinary Ourang, whose muzzle projected much more than those of the very young specimens hitherto described. T described it in a memoir read before the Acad, des Sciences in 1818. Tilesius and Rudolphi appear also to have had it. See the Mem. of the Acad, of Berlin, 1824, p. 131. QUADRUMANA. 49 have no forehead, and the cranium retreats from the crest of the eye-brov . The name of Ciiimpanses might be exclusively applied to them. S, troglodytes , L. (The Chimpanse)* is covered with black or brown hair. Could any reliance be placed on the accounts of tra- vellers, this animal must be equal or superior to man in stature, but no part of it hitherto seen in Europe indicates this extraordinary size. It inhabits Guinea and Congo, lives in troops, constructs huts of leaves and sticks, arms itself with clubs and stones, and thus re- pulses men and elephants; pursues and abducts, as is said, negro women, &c. Naturalists have generally confounded it with the Ourang-Outang. When domesticated he soon learns to walk, sit, and eat like a man. We now separate the Gibbons from the Ou- rangs. Hilobates, Illig. The Gibbons have the long arms of the true Ourangs, and the low fore- head of the Chimpanse, along with the callous buttocks of the Guenons, differing however from the latter in having no tail or cheek-pouch. They all inhabit the most remote parts of India. S. lar. L, ; Buff. XIV. 2 ; Onko , Fred.

The young are of a uniform yellowish white — it is very agile, and lives in pairs — its Malay name, Wouwou, is taken from its cry.

We might separate from the other Gibbons the Siamang. S. syndactila , Raff., Fred.

It is black — the chin and eyebrows red — lives in numerous troops, which are led by courageous and vigilant chiefs, which, at sunrise and sunset, make the forest ring with the most frightful cries. Their larynx has a membranous sac connected with it.

In the confined state these animals will- ingly received every sort of food, with the exception of that of animal; they scarcely ever eat any portion, before they broke the whole. The male was capricious, and sometimes ill tempered, and we have seen the female always acting in such a man- ner that shewed fear as well as gentle submission; she usually approached the male by proceeding around him in a circular walk, and with her eyes constantly upon him, as if to watch the favourable moment for shortening the distance between them. The jealousy shewn by him when a visitor took notice of the female, was instantly mani- fested by repeated blows. — Eng. Ed. 54 MAMMALIA, C. papio, Desra. ; Sim. sphynx , Lin. ; Papion, Buff.

The Mandrills, Of all the monkeys, have the longest muzzle (30°); their tail is very short ; they are very brutal and ferocious ; nose as in the preceding. Sim. maimon and mormon, Linn. ; Boggo, Choras, Buff. XIV. XVI. XVII. et Supp. VII. 9. (The Mandrill). Greyish brown, inclining to olive above; a small lemon-yellow-coloured beard on the chin ; cheeks blue and furrowed. The nose in the adult male becomes red, particularly at the end, where it is scarlet, which has been the cause of its being deemed, erroneously, a distinct species §. * Those which have been figured as having it short, as the Papions of Buffi XIV. pi. 13 and 14, &c. had it cut off.

It is difficult to imagine a more hideous or extraordinary animal. He nearly at- tains the size of a man, and is a terror to the negroes of Guinea.

IX. pi. 37, from a young specimen from India, and Hist, des Mammif. from the adult. (The Drill). Yellowish grey; face black; tail very short and thin ; in old ones the fur becomes darker, and the chin of a brilliant red. The Monkeys of the New Continent Have four grinders more than the others — thirty-six in all; the tail long ; no cheek-pouches ; buttocks hairy ; no callosities ; nostrils opening on the sides of the nose, and not underneath. All the great Quadrumana of America belong to this division. Their large intestines are less in- flated, and the caecum longer and more slender than in those of the eastern continent. The tails of some of them are prehensile — that is, its extremity can twist round bodies with sufficient force to seize them as with a hand. They are more particularly designated by the name of Sapajous, Cebus , Erxleben*. At their head may be placed the Alouattes (Mycetes, //%.), which are distinguished by a pyramidal head, the upper jaw of which descends much below the cranium, as the branches of the lower one ascend very high for the purpose of lodging a bony drum, formed by a vesicular in- flation of the hyoid bone, which communicates with the larynx, and gives to their voice an astonishing volume, and a frightful sound. Hence their name of Howling Monkeys. The prehensile portion of the tail is naked beneath. There are several species, whose distinguishing characters are not yet well ascertained, for the colour of the fur on which they are established varies with the age and the difference of sexes. Simia seniculus , Buff. Supp. VII. 25. (Red Howling Monkey). It is often sent to us from the forests of Guiana, where it lives in troops ; size that of a large fox ; colour, a reddish chesnut, rather deeper at the head and tail. The Allouatte ourson ( Stentor ursinus , Geoff.), llumb. Obs. Zool. I. pi. 30, must differ from it very slightly; but it would appear that there are many others, some of which are black or brown, others of a pale colour. In certain species this pale tint is peculiar to the females -j\ * Cebus or Cepus , K>j7ro?, names of an Ethiopian monkey, which, from the de- scription of iElian, lib. xxvii. c. 8, must have been the Patas. t Marcgrave, Braz. 226, speaks of a black Guariba, with brown hands, that Spix thought he had found in his Seniculus niger. Mem. de Munic, for 1813, p. 333. Mycetes rvfimanus, Kuhl. Marcgrave, 227, speaks of another species, all black and bearded, fig. p. 228, un- der the wrong name of Exquima, which must have been, it is probable, the Mycetes 56 MAMMALIA. The Common Sapajous have the head flat, and the muzzle slightly prominent — facial angle 608. In some of them, the anterior thumbs are either totally, or nearly so, hidden under the skin, and the prehensile part of the tail naked beneath. M. Geoff, has formed them into a genus by the name of Ateles*. The first species, the Charnels , Ateles pentadactylus, Geoff., differs again from the others in having a slight projection of the thumb, though it is only of one phalanx, but without a nail; its fur is black. A second species, the Mikiri , At. hypoxanthus, Pr. Max.; Brachyteles macrotarsus , Spix, pi. i., has also a very small thumb, and sometimes even a nail. The fur is yellowish, ferruginous to- wards the tail. These two species are separated by Spix under the name Brachyteles. They connect the Ateles with Lagothrix. The other Ateles, to which alone Spix restricts that name — Coaita , Buff. — have no apparent thumb whatever. Such are the following: A. paniscus ; Simia panisc. L. ; Coaita, Buff. XV. 1. (The Coaita). Completely covered with black hair, like the Chamek, but without any visible thumb ; face, flesh-colour. A. ater, Fr. Cuv. Mammif. (The Cayou). Face black, like the rest of the body. A. marginatus, Geoff. The Chuva, Humb. or the Coaita a face bordee, Ann. Mus. XII. pi. 10. Black, with a border of white hairs round the face. A. belzebuth; Sim. beelzeb., Briss. The Marimonda, Humb. or Coaita a ventre blanc , Geoff.; Ann. Mus. VII. pi. 16. Black above ; white beneath ; circumference of the eyes flesh-coloured. A. arachnoides, Geoff. Ann. Mus. XIII. pi. 9. (The Spider Monkey). Grey, fawn-coloured or red; eyebrows black. All these animals are natives of Guiana or Brazil ; their fore-feet are very long and slender, and their gait remarkably slow'f’. barbatus, Spix, pi. 32. The female, lb. pi. 33, is of a light yellowish grey. The male must be the Mycetes niger of Kuhl and Prince Maximil. de Neuwied. The Caraia of d’Azzara, which is black, breast and belly of a dark red, the female brownish, may be referred to this species. Pr. Max. has another Mycetes ursinus, which appears to be much browner than the ursinus of M. Geoffroy, and to approximate nearer to the M. fuscus , or the M. discolor of Spix, pi. 30 and 34. This latter rather appears to be the St. fuscus of Geoffroy. The Straw-coloured Alouatte, Stentor stramineus, Geoff, and the Myc. stramineus, Spix, pi. 31, of a yellowish grey, appears from its cranium to be of a different spe- cies, but it may merely be the female of a preceding one. It is easily seen, also, that if their characters are so uncertain, their synonymes must be much more so. Add the St. flavicaudatus, Geoff, of a black brown, with a yellow streak on each side of the tail. * Ann. du Museum, VII. 260, et seq. f They exhibit some remarkable resemblances to man in their muscles. Of all animals, they alone have the biceps of the thigh made like ours. QUADRUMANA, Lagothrix(g), Geoff. — Gastrim argus, Spin. Head round, like the Ateles; a thumb developed like the Alouattes; tail partly naked, like the one and the other. Such are the L. Humbol- dii, Geoff. ; the Caparo , Humb. ; Gast. olivaceus, Spix, pi. 28 (the Cap- paro); and the Grison, (ox Lag. canus, Geoff.); or Gastr. infumatus , Spix, 29. (The Silver-haired Monkey). Monkeys from the interior of South America, said to be remarkable gluttons. The other Sapajous (Cebus, Geoff.) have a round head, distinct thumbs, and the tail hairy, though prehensile. The species are more numerous than those of the Alouatte, and are characterized with nearly as much difficulty. Some of them have the hairs on the forehead of a uniform length, such as the — Sim. appella, L. (The Sajou); and the S. capucina , L. ; Buff. XY. 4, 5, and 8, 9. (The Capuchin). Both of them of different browns; in the first, the circumference of the face is blackish; in the second it is whitish ; but the shade of colour in all the rest of their bodies varies between a brownish black and a fawn-colour, sometimes even a white. The shoulders and breast are however generally lighter, and the calotte and hands darker*. Others, again, have the hairs of the forehead so disposed as to form a kind of aigrette, such as the Sim. fatuellus, Gm. ; Buff. Supp. VI-1. 29. (The Horned Sajou). This animal has a tuft of black hairs on each side of the forehead -f. The disposition of these monkeys is mild and gentle, their motions quick and light, and they are easily tamed. Their name of Weeping Monkeys is derived from their soft plaintive voice. * The Sajoas and the Sais vary so much from a brown to a yellow, that, were there not intermediate varieties, we should be tempted to make many species of them. Such Is the case with the Sim. trepida, syrichta, lugubris, flavia, L. and Schreb., as well as some of those distinguished by M. Geoffroy, Ann. du Mus. XIX. Ill and 1 12. Spix has recently, and in our opinion improperly, multiplied them still more. We would refer to the Sajou {Sim. appella , Lin.) the Cebus robustus, Pr. Max., which appears to us to be an old one of that species. The Ceb. macrocephalus, Spix, pi. 1, does not seem to differ from it, so far as regards the species. We refer to the Sat (S. capucina, Lin.) the Sai a gorge blanche, Buff. (S. kypolencos); the Cebus libi - dinosus, Spix, 2; the Ceb.xanthosternus, Pr. Max., or the Ceb. xanthocephalus, Spix, 3; the Ceb. cucullalus, id. 6. We should be more inclined to consider as distinct species, the Sajou a pieds dores, Fred. Cuv., the Sajou brun, id. or Ceb. unicolor, Spix, pi. 4; the Sim. flavia, Schreber, 31, B, from which the Ceb. gracilis, Spix, pi. 5, seems to differ only in the stuffing — but that we require numerous observations, made upon the spot which these ani- mals inhabit, before we can hope to establish their species in any other than an arbi- trary manner. f Here should come the Cebus cirrhifer, Geoff, and the Ceb. of the same name, of Pr. Max., but which is different. Ceb. cristatus, Fred. Cuv. (J3^(«) The existence of this animal was not known until Humboldt discovered it in South America: — He describes it under the name of Simia Lagothrica. A remark- ably fine specimen was presented lately to the Surrey Zoological Gardens, which was brought from Para, on the Iliver Amazon, in South America. Its habitation is now considered to be the northern portion of South America, between the Equator and five degrees of north latitude. — Enu. Ed. 58 MAMMALIA. In the Saimiri the tail is depressed, and almost ceases to he prehen- sile ; the head is very much flattened ; in the interorbitar partition of the skeleton there is a membranous space. There is only one known ; the Simia sciurea, Buff. XV. 10. (The Saimiri). Size of a squirrel; of a yellowish grey ; fore-arms, legs, and the four extremities of a yellowish fawn-colour ; end of the nose quite black. Those of the American monkeys, whose tails are not at all prehensile, are called Sakis*. Several of them have the tail long and tufted, whence they have been also termed Fox-tailed Monkeys: their teeth project for- wards more than those of the others. They are the Pithecia of Des- marets and Illiger. Simia pithecia, L. ; Buff. XV. 12; Pithecia inusta , Spix, pi. 10. (The Yarke). Blackish; circumference of the face whitish.

Supp. VII. 31 ; Pith, capilla- mentosa , Spix, pi. 11. (The Bed-bellied Saki). Brown, with a red belly. Spix distinguishes those species whose tails, although tufted, are shorter than the body, by the name of Braciiiurus. His Br. Ouaraki , Sp. pi. 8, has a fawn-coloured body ; head, neck, arms, and feet black. To this should be referred, provided always it is another species, the Sim. melanocephala , Humb. Obs. Zool. p. 29 ; yellow, with a black head. In some, also, the Callithrix, Geoff, or Sagouins , Fr. Cuv. the tail is slender, and the teeth do not project. The Saimiri were associated with them for a long time, but the head of the Sagouins is higher, and their canine teeth much shorter.

It is a nocturnal animal of South Ame- rica*. They are all from Guiana or Brazil. Ouistitis («), — Hapale, Illig. — Arctopithecus, Geoff. A small genus, similar to the Sakis, and for a long time confounded with them in the great genus of monkeys. In fact, like the generality of the American monkeys, they have the head round ; face flat ; nostrils lateral ; buttocks hairy ; no cheek-pouches, and, like the Sakis in particular, the tail not prehensile. They have only, however, twenty grinders, like the monkeys of the ancient continent; all their nails are compressed and pointed, those of the hind thumbs excepted, while their anterior ones are so slightly separated from the fingers, that it is with hesitation we assign to them the name of quadrumana. They are all pretty little creatures, of agreeable forms, and easily tamed. M. Geoffroy distinguishes the Ouistitis , properly so called, which he names Jacciius, and whose peculiar characters are pointed inferior in- cisors, arranged on a curved line, equal to the canines. Their tail is an- nulated and well covered with hairs ; the ears generally ornamented with a hairy brush. Sim. jacchus, Lin. ; in Paraguay the Titi, Buff. XV. pi. 24. (The Common Ouistiti). Tail tolerably well tufted, coloured by rings of brown and white ; body greyish-brown ; two large tufts of white hairs before the ears. From nearly every part of South America^. M. Geoffroy calls those species which have inferior trenchant incisors placed nearly in a straight line, and less than the canines, Midas. Their tail is also more slender and not annulated.

Max., lib. 2, has the same tufts, but the whole head and fore part of the neck are white. — His J.hn- vierulijer has the breast, shoulders and arms white. — The J. albicollis, Spix, pi. 25, lias the spot on the forehead, tufts of the ears and a large collar all white. In some of them, on the contrary, all the white has disappeared. See Annal. du Mus., XIX. p. 1 19 122. f I suspect the Mid. bicolor,. Spix, pi. 24, is merely a variety of the Sim. cedipus , and his M my s tax of the M. labiatus. »*(«)T he name of Ouistitis is given to the animals of this species from the peculiar sound which they emit, and which is very closely imitated if we express separately and at intervals the successive syllables which compose the word. — Eng.

From the Amazon. Lemur (a), Lin. The Lemurs, according to Linnaeus, comprehend all the Quadrumana which have in either jaw incisors differing in number from four, or at least differently directed from those of the Monkeys. This negative character could not fail to embrace very different beings, while it did not even unite those which should be combined. Geoffroy has established several divisions in this genus which are much better characterized. The four thumbs of these animals are well developed and opposable, and the first hind finger is armed with a pointed, raised nail ; all the other nails are flat. Their fur is woolly ; and their teeth begin to exhibit sharp tubercles catching in each other as in the Insectivora. Lemur. — Makis, properly so called. Six incisors in the lower jaw compressed and slanting forwards, four in the upper that are straight, the intermediate ones being separated from each other; trenchant canines; six molares on each side above; six be- low ; ears small.

Besides the peculiar characters of the Lemurs mentioned in the text, there are others which may be seen in the specimens in the London Zoological Gardens, namely, the elongated face, the round and prominent eyes, the long curved nail on the index finger of the hinder hand; they possess scarcely any external character in common with the monkey, save in the prehensile power of the hands. There is reason to believe that the Lemurs are occasionally, or partially, carnivorous, and the nature of their teeth fully justifies the opinion. — Eng. Ed. QUADRUMANA. 61 heads, have been called Fox-nosed Monkeys. Their food is fruit. Their species are very numerous, and are only met with in the island of Mada- gascar, where they appear to replace the monkeys, none of which, it is said, are to be found there.

(a) In the examination of a specimen of this species which recently died in the Zoological Gardens in Regent’s Park, the distribution of the arteries to the limbs was found to be analogous to that very peculiar one which obtains in the Lemurs and Sloths, except, that in the Loris the structure and distribution of the vessels supply- ing the blood appeared to be destined more to the object of increasing the tenacity of the animal’s grasp, and to allow to him to prolong the state of muscular contraction with impunity. — Eng. Ed. CARNARIA. ORDER HI. G o iJ CARNARIA (a). — CARNIVOROUS ANIMALS. This order consists of a considerable and varied assemblage of ungui- culated quadrupeds, possessing, like Man and the Quadrumana, the three sorts of teeth, but which have no opposable thumb to their fore-feet. Their food is animal, and the more exclusively so, as their grinders are the more trenchant. Those which have them, either wholly or in part tuberculous, live more or less on vegetable substances, and those in which they appear with conical points, live principally on insects. The articu- lation of their lower jaw, having a cross-wise direction, and its parts being combined on the principle of the hinge, is incapable of horizontal motion, and possesses merely the faculty of opening and of closing. Their brain has the usual depressions, but it has no third lobe, nor does it lie upon the cerebellum in these animals any more than it does in the families hereafter to be described; their orbit is not separated from the temporal fossa in the skeleton, the cranium is narrowred and the zygo- matic arches widened and raised, in order to give more strength and vo- lume to the muscles of their jaws. Their predominant sense is that of smell, and their pituitary membrane is generally spread over numerous bony laminae. The fore-arm has the power of rotating in nearly all of them, although with less facility than in the Quadrumana, and they never have in the fore-feet thumbs opposable to the other toes. Their intes- tines are less in volume in consequence of the substantial nature of their food, and in order to prevent the putrefaction which flesh would necessa- rily experience in being kept too long in a canal of great length. Besides, their forms and minute portions of their organization vary considerably, and are the source of analogous varieties in their habits, and to a degree which makes it impossible to arrange their genera upon one common scale, so that it becomes indispensable to form them into several families, which are variously connected together by multiplied relations. ( a ) From some experiments recently performed in the Zoological Gardens in Regent’s Park, it would appear that Carnivorous Mammalia fed with two meals a day, are by no means in such good condition as those which have the same quantity of flesh in one meal only. Two Leopards were chosen for the first experiment. One, which weighed 91 lbs., was fed in the usual manner, on 4lbs. of beef every day in one meal — the other, which weighed 1004 lbs., was supplied with the same quan- tity of beef, but one-half was given in the morning and the other half in the even- ing. After an interval of five weeks, during which the animals were fed in this way, they were weighed; when it was found that, whilst the Leopard that had his food all at once, gained lib. in weight; the other lost £lb., and his temper became very much worse. Two Hyaenas were subjected to a similar experiment, which was at- tended with pretty nearly the same results. — Eng. Ed. 64 MAMMALIA. THE FIRST FAMILY OF CARNARIA. THE CHEIROPTERA Retain some affinities with the Quadrumana by the pendulous penis, and by the mammae which are placed on the chest. Their distinguishing character consists in a fold of skin, commencing at the sides of the neck, and extending between the four members and fingers of the anterior feet, supports them in the air, and even enables such of them to fly as have their hands sufficiently developed for that purpose. This disposition required strong clavicles and large scapulae to give the necessary solidity to the shoulder, but it was incompatible with the rotation of the fore-arm, which would have diminished the force of the effort requisite for flight. They have all four great canines, but the number of their incisors varies. They have long been divided into two genera, founded upon the extent of their organs of flight ; but the first of these requires several subdivisions. Vespertilio* Lin. The Bats have the arms, fore-arms, and fingers excessively long, form- ing, with the membrane that occupies their intervals, true wings, possess- ing even a greater extent of surface than those of Birds — they conse • quently fly very high, and with great rapidity. The thickness of then- pectoral muscles is proportioned to the motions they have to execute, and there is a ridge in the middle of the sternum like that of Birds, to which they are attached. The thumb is short and armed with a claw, by which they are enabled to creep and to suspend themselves. Their hind feet are weak and are divided into five toes, almost always of equal length, armed with trenchant and pointed nails. They have no caecum in their intes- tines. Their eyes are excessively small, but their ears are frequently very large, and together with the wings form an enormous membranous surface, which is almost naked, and so extremely sensible, that the Bats are conducted through all the sinuosities of their labyrinths, even after their eyes have been plucked out, probably by the diversity of the im- pressions of the air. They are nocturnal, and in our climate pass the winter in a state of lethargy. During the day they suspend themselves in obscure places. They generally produce two young ones at a birth, which they keep fastened to their mammae, and whose size is consider- able in proportion to that of the mother. This genus is very numerous, and offers many subdivisions. We must begin by separating from it the Pteropus, Briss. The Bats called the Roussettes, have trenchant incisors in each jaw, and grinders with flat crowns*; their food, consequently, consists chiefly * The grinders have properly two longitudinal and parallel projections separated by a groove, which wear away by attrition. CARNaRIA. 65 of fruit, of which they destroy considerable quantities ; they know, how- ever, how to pursue birds and small quadrupeds. They are the largest Bats known, and their flesh is eaten. They inhabit the East Indies. Their membrane is deeply notched between their legs ; they have no tail, or nearly none ; the index finger, which is but half the length of the medius, has a third phalanx, and a little nail which is wanting in the other Bats ; each of the other fingers, however, has but two phalanges. The muzzle is simple, the nostrils are widely separated, the ears are of a middling size, but without a tragus (a), and the tongue is bristled with points that curve backwards ; the stomach is an elongated sac, unequally inflated. They have never been found, except in Southern Asia or the Indian Archipelago. I. The Roussettes without tails , with four incisors m each jaw * * * § . P. edulis, Geoff. (The Black Roussette, or Edible Bat). Blackish brown, deepest beneath, nearly four feet between the extremities of the wings. From the Straits of Sunda and the Moluccas, where they are found in great numbers during the day suspended to the trees. To preserve fruit from their attacks, it is necessary to cover it with nets. Their cry is loud and resembles that of the goose. The Bat is taken by holding to him a bag fastened to the end of a rod ; the flesh is esteemed a delicacy by the natives, but Europeans dislike it on account of its musky scent "j'. Pter. vulgaris , Geoff. ; Buff. X. 14. (The Common Roussette). Brown, face and sides of the back fawn-coloured. From the Isle of France and Bourbon, where it is found on the trees in the forests. Its flesh has been compared to that of the hare and partridge. Pter. rubicollis, Geoff.; Buff. X. 17. (The Red-collared Rous- sette, the Roussette of Buffon). Greyish brown, the neck red. From the same islands, where it lives in the hollows of trees and in holes in rocks J. II. With a small tail and four incisors in each jaw. M. Geoffroy was the first who described the species of this sub- division. One of them woolly and grey, Pter. vegypticus, is found in the caves of Egypt. Another is reddish, and has a somewhat longer tail, half involved by the membrane — Pter. amplexicaudus , Ann. du Mus. tom. XV. pi. 4. From the Indian Archipelago, &c. §. * Linnaeus confounded them under his species Fespertilio vampirus. f According to Zemminck, the Roussette of Edwarde Geoff., Edw. 108; it is fawn-coloured, and deep brown in the back: it is only the young state of this species.

Ed. VOL. l. MAMMALIA. 66 III. According to the characters of M. Geoffroy, we further separate from the Roussettes the Cephalotes which have the same kind of grinders, but whose index finger, short, and consisting of thre'e phalanges, like that of the preceding, wants, however, the nail. The membranes of their wings, instead of meeting at the flank, are joined to each other on the middle of the back, to which they adhere by a vertical and longi- tudinal partition. Very often they have but two incisors. C. Peronii, Geoff. ; Ann. du Mus. XV. pi. 4. (The Ceplialote of Peron). Brown or red. From Timor. The Roussettes being withdrawn, we have the true Bats left, which are all insectivorous, and have three grinders on each side in each jaw, bristled with conical points, that are preceded by a variable number of false molars. Their index finger never has a nail, and, one subgenus ex- cepted, the membrane is always extended between the two legs. They should be divided into two principal tribes. The first has three ossified phalanges in the middle finger of the wing, but the remainder, in- cluding the index itself, consists of but two. To this tribe, which is almost exclusively foreign, belong the following subgenera. Molossus, Geoff. — Dysopes, Illig. Has the muzzle simple ; ears large and short, arising near the angle of the lips, and uniting with each other on the muzzle ; the tragus short, and not enveloped by the conch (a). The tail occupies the whole length of their inter-femoral membrane, and, more frequently, even extends beyond it. They have almost always two incisors in each jaw, though, according to M. Temminck, several of them have at first six below, of which four are successively lost. The Dinops of M. Savi belong to the Molossus with six inferior in- cisors. There is one species in Italy — Dinops cestonii , Savi, Giorn. de Letter., No. 21, p. 230. M. Geoffroy calls those in which he has counted four inferior incisors Nyctinomus*. The Molossi, at first, were only found in America ■f'; at present, how- * The Nyctinome of Egypt, Geoff, Eg.

Some of them have the thumb of the hinder feet placed at a greater distance from the first finger than the fingers are from each other, and endowed with a power of sepa- rate motion, a character on which, in a species where it is very strongly marked, M. Horsfield has established his genus Cheiromeles j~. It is here, perhaps, that we should also place the Thiroptera of Spix, which appear to have several characters of the Molossi, and whose thumb has a little concave palette peculiar to them, and by which thev are ena- bled to cling more closely Noctilio, Lin., Ed. XII. Has the muzzle short, inflated, and cleft, as in a double hair-lip, fur- nished with warty tubercles and odd looking seams ; ears separate ; four incisors above, and two below; tail short, and free above the inter-femoral membrane. The species best known is from America. It is of a uniform fawn-colour — Vespert. leporinus, Gm. Schreb. LX. §. Phyllostoma, Cuv. and Geoff. In which the regular number of incisors is four to each jaw, but in which a part of the lower ones frequently fall, being forced out by the growth of the canines: they are moreover distinguished by a membrane in the form of a leaf, which is reflected crosswise on the end of the nose. The tragus of the ear resembles a small leaf, more or less indented. The tongue, which is very extensible, terminates in papillae, which appear to be so arranged as to form an organ of suction — the lips also are furnished with tubercles, symmetrically arranged. They are all from America, run along the ground with more facility than the other bats, and have a habit of sucking the blood of animals. 1. The Phyllostomes without a tail. — Vampirus, Spix.
