Part 11

The colour of the common Baboon is reddish brown; his face and hands are black, and his upper eyelids white. The hair of his cheeks forms a considerable tuft on each side; and the under surface of his body is but sparingly covered. In bulk he is equal to a middle sized dog; his proportions are thickset and inelegant; but he is by no means dull or inactive. When young, he is gay, playful, and docile; but as he grows older he becomes untractable, malicious, and ferocious. He is sometimes even dangerous, his muscular strength and agility, together with the great power of his teeth and jaws, rendering him a formidable opponent. On this account it is absolutely necessary to keep him strictly confined. He is a native of Africa, and more especially of the tropical parts of its western coast.

THE WHITE-HEADED MONGOOS.

_LEMUR ALBIFRONS._ GEOFF.

Belonging to a different tribe of the same grand division with the true Monkeys, from which they are more readily distinguished by their general form and habit than by any very remarkable deviation in their structure or organization, these agile and playful little creatures form a group which naturally follows in immediate succession. The technical peculiarities on which their separation from the Monkeys is founded are usually deduced from their teeth and nails; but other and more obvious characteristics are afforded by the form of their heads, of their tails, and of their hinder extremities, and these assist in confirming a distinction which might otherwise be regarded as arbitrary and unnecessary. The teeth of the Lemurs are, like those of man and of the Monkeys of the Old World, thirty-two in number, and consist of four incisors, two canines, and ten molars in the upper jaw, and of six incisors, two canines, and eight molars in the lower. Such at least is the usual statement with respect to their dentition; but M. Geoffroy maintains, on the other hand, that the number of incisors is equal in both jaws, and coincides with that of the Monkeys; the two outermost of the six, which are larger than the rest, being in his opinion the true canines; while the canines, commonly so called, are in fact only the first of the series of molars. This conjecture unquestionably derives considerable strength from the fact that, when the animal closes its mouth, the supposed canines of the lower jaw pass behind those of the upper, a position directly contrary to that which they uniformly assume in every other animal that is furnished with that kind of teeth. On each of their four hands they have four fingers of moderate length, and a thumb which is capable of being opposed to them almost equally well with that of the other Quadrumana; they are consequently enabled to grasp whatever they seize with the greatest precision. The peculiarity of their nails consists in the shape of that of the index of the hinder hands, which forms an elongated, curved, and pointed claw, approaching in some degree to those of the carnivorous quadrupeds. All the rest of their nails are broad and flat like those of the Monkeys. Their posterior extremities are longer than their anterior; and their body and limbs are light, graceful, and well proportioned. The tail, which is of uniform thickness throughout, is longer than the body, and, in common with it, is clothed with long, soft, and woolly hair. The head is long, triangular, and gradually tapering into a slender and pointed muzzle, which, in proportionate length, far exceeds that of any of the Monkeys; the ears are short and rounded; and the whiskers but little developed.

The whole of the genus thus characterized are natives of Madagascar and of two or three of the smaller islands in its immediate vicinity. They appear to occupy in that remarkable and very imperfectly known country the place of the Monkeys, none of which have yet been detected within its precincts. They are said to live in numerous troops upon the trees, and to feed upon fruits and insects; but their habits in a state of nature have not yet been observed with sufficient accuracy to enable us to form any clear idea of their mode of existence. In captivity they are particularly tame and good tempered, fond of being noticed, delighting in motion, and climbing and leaping with surprising agility. They are, however, in some degree nocturnal; and when undisturbed pass a considerable portion of the day in sleep. If alone, they roll themselves up in the form of a ball, and wind their long tail in a very curious manner round their body, apparently for the purpose of keeping themselves warm; for they are naturally chilly, and delight in basking in the rays of the sun, or in creeping as close as possible to the fire. When two of them are confined together, they interlace their limbs and tails after a singular fashion, and placing their heads in such a position as that each may, if disturbed, see what is going on behind the other’s back, fall comfortably asleep.

The species to which the beautiful pair in the Menagerie belong has all the habits of its group. It is characterized by the clear fulvous brown colour of the upper surface of the body and outer side of the limbs, gradually becoming lighter on the under and inner surfaces, and deepening in its shade towards the tail, the greater part of which is nearly black. The muzzle and the hands are bluish black. The male has the whole of the forehead, the sides of the cheeks, and the under part of the lower lip covered with a white fur, which in the female is of a blackish gray and much less developed; her general colour is also of a lighter tinge. This remarkable difference would lead us to question the specific identity of the two animals, were we not assured by M. F. Cuvier that he had verified the fact by what is usually regarded as an unequivocal test. Mr. M’Leay has, however, thrown considerable doubt upon the accuracy of the inference thus attempted to be drawn, by exhibiting to the Linnean Society a female, in whom the white fur of the head was as distinctly developed as in her male companion. The whole of the species of this group require, in fact, an accurate revision.

THE KANGUROO.

_MACROPUS MAJOR._ SHAW.

The very peculiar structure from which the Marsupial animals derive their name has been regarded by almost every naturalist who has written on the subject as so essential a deviation from the common type, that, setting aside all considerations of form or habits, and regardless even of those technical characters on which so much reliance is usually placed, they have for the most part agreed in uniting under the same family designation every animal in which it occurred. This peculiarity consists in a folding or doubling of the skin and its appendages beneath the lower part of the belly in the females, in such a manner as to form an open pouch or bag, in which the young are contained from a very early period, in which the process of suckling takes place, and in which, even for some time after they have acquired sufficient size and strength to leave it, the little ones continue to take refuge.

But the presence of this one anomalous characteristic is accompanied by so many striking discrepancies in other parts, that, limited as this tribe is in number, most of the principal forms of Mammalia find analogous representations among its groups. Thus the Opossums exhibit characters in some measure intermediate between the Quadrumana and the Carnivora, to which latter the Dasyuri, another Marsupial group, closely resembling the Civets in form and habits, approach very nearly; while the herbivorous races of the tribe might occupy a station between the Rodent and Ruminant Orders, with each of which they exhibit various degrees of relationship. This want of uniformity in the essential parts of their organization necessarily gives rise to much difficulty in determining their position in the system. The mode of classification now most generally followed is perhaps, under all the circumstances, the best that could at the present moment be adopted; although it must be owned that the purely herbivorous species arrange themselves with a very ill grace under a subdivision of the order Carnivora. Placed, however, as they are at the end of that order, and immediately before the Rodentia, the regular gradations from the type of the former to that of the latter, which occur in their different groups, become most distinctly manifest.

With the exception of the Opossums, which are natives of America, the tribe is peculiar to New Holland and its appendages, and to some of the islands which form the great chain of connexion between that insular continent and South-eastern Asia. The former is, however, their head quarters, and the species which are found beyond its limits are few in number compared with those which people its territory, and, what is more remarkable, people it to the exclusion of nearly all the other Mammalia; the dog alone, the universal concomitant of man, and one or two species of rats, disputing with them their title to its exclusive possession; for those paradoxical creatures, the Ornithorhynchus and Echidna, if really mammiferous, approximate closely in structure to the Marsupial tribe.

The largest of these animals are the Kanguroos, whose generic characters we shall now proceed to describe. Their teeth are only of two kinds, the canines being altogether wanting. The incisors are six in the upper jaw, and two only in the lower; the former short, and arranged in a curved line, and the latter long, pointed, closely applied to each other, and directed forwards. The molars are separated from the incisors by a considerable vacant space, and are five in number on each side of each jaw. The most remarkable peculiarity in the external form of these animals consists in the extreme disproportion of their limbs, the anterior legs being short and weak, while the posterior are extremely long and muscular. The tail too is excessively thick at its base, of considerable length, and gradually tapering; and this singular conformation enables it to act in some measure as a supplemental leg, when the animal assumes an erect or nearly erect posture, in which position he is supported as it were on a tripod by the joint action of these three powerful organs. By means of this combination they will, when flying from danger, take a succession of leaps of from twenty to thirty feet in length and six or eight in height; but even in their more quiet and gradual mode of progression they also make use of their tail in conjunction with their four extremities. The fore feet are furnished with five toes, each terminating in a moderately strong and arcuated claw. The hinder extremities, on the contrary, have only four toes, the two interior of which are united together so as to form the appearance of a single one furnished with two short and feeble claws; the third is long, of great strength, and terminated by a large and powerful claw having the form of a lengthened hoof; and the fourth, the most external of the series, is similar in character to the third, but of much smaller dimensions. The head and anterior part are small and delicate, and appear quite disproportioned to the robust posterior half of the body; and this disproportion is equally striking, whether the animal assumes an erect position or crouches forwards upon all fours. In either case the whole extent of the soles of the posterior feet, which are of great length, is applied to the surface of the ground. Although differing from all the Rodent animals in the number of the cutting teeth of the upper jaw, the Kanguroo has the deep fissure in the upper lip, with which nearly all that order are furnished, and of which the hare offers a familiar and proverbial instance.

These singular animals were among the first fruits which accrued to natural history from the discovery of New South Wales, a country which has since proved so fertile in new and remarkable forms both of the animal and vegetable creations. Their natural habits in a wild state are still, however, very imperfectly known. They appear to live in small herds, perhaps single families, which are said to submit to the guidance of the older males, and to inhabit in preference the neighbourhood of woods and thickets. They are, as might be inferred from the small size of their mouths and the peculiar character of their teeth, purely herbivorous, feeding chiefly upon grass and roots. Their flesh is eaten by the colonists, by whom it is said to be nutritious and savoury, an assertion which is confirmed by those who have partaken of it in England. In order to procure this they are frequently hunted in their native country; but the dogs who are employed in this service sometimes meet with dangerous wounds, not only from the blows of their powerful tail, which is their usual weapon of defence, but also from the claws of their hind feet, with which they have been known to lacerate the bodies of their assailants in a shocking manner. But, unless when thus driven to make use of such powers of self-defence as they possess, they are perfectly harmless and even timid; and, when domesticated, are not in the least mischievous. In several collections in this country, and particularly in the Royal Park at Windsor, from which the specimens in the Menagerie were obtained, they have become almost naturalized, and appear to be but little affected by the change of climate. When confined in a small enclosure, they uniformly make their path round its circuit, seldom crossing it or passing in any other direction except for the purpose of procuring their food. Their whole appearance, and especially their mode of progression, is singularly curious and even to a certain extent ludicrous.

Modern naturalists have attempted to distinguish several species among the Kanguroos; but as the characters on which these are founded consist merely in difference of size and slight modifications of colour, a much more complete acquaintance with them than we yet possess is requisite before they can safely be adopted. Our specimens are of a brownish gray above, somewhat lighter beneath, with the extremity of the muzzle, the back of the ear, the feet, and the upper surface of the tail, nearly black, and the front of the throat grayish white. Since they have been confined in the Menagerie, the female has once produced young; a circumstance by no means unfrequent even in this country among those which are less restricted of their liberty and are suffered to roam at large in a meadow or a park. They are fed, like the domesticated Ruminants, upon green herbage and hay; and are extremely tame and good tempered.

THE AFRICAN PORCUPINE.

_HYSTRIX CRISTATA._ LINN.

Although the Rodent order, next to the Carnivorous, is the most numerous in species, the Porcupine is the only animal belonging to it which is at present contained in the Menagerie. The animals of this division, consisting chiefly of “rats and mice and such small deer,” have indeed, with some few exceptions, so little of interest for the mere casual visiter of an exhibition, that it is rarely that they are sought after unless by the scientific collector. They are at once distinguished from the Carnivora by the total absence of canine teeth; and have uniformly two incisors in each jaw, projecting forwards and generally of considerable size, separated from a variable number of grinders by a vacant space.

From the other animals of the order the Porcupines are so readily distinguished by the long and pointed spines with which their body is armed, that it is unnecessary to dwell on their generic characters. The common Porcupine, when fully grown, as in the remarkably fine specimen figured over leaf, measures more than two feet from the tip of the nose to the origin of the tail. The spines, which are supported by a slender pedicel, thickly clothe the upper and posterior parts of the body, the largest being more than a foot in length; they are regularly surrounded by alternate rings of black and white. The head and neck are crested with long, bristly, black hairs, forming a kind of mane, and all the rest of the body is covered with short black hair.

The Porcupine is a native of Africa and the south of Europe; he chooses for his abode the most arid and solitary situations, and passes the daytime secluded in the burrows which he digs for his habitation, quitting them only at night to provide his subsistence, which consists entirely of vegetable substances. He is a remarkably timid animal, and never makes use of his formidable weapons except in self-defence; if alarmed, his spines immediately become erected, and woe be to the enemy who should dare to attack him open-mouthed when in that posture.

THE ASIATIC ELEPHANT.

_ELEPHAS INDICUS._ CUV.

The opportune arrival of a beautiful little Elephant, an animal which has for some time been a desideratum to the Menagerie, fortunately enables us to add to our list of subjects that which in all probability presents the most generally attractive spectacle among the whole class of Mammiferous Quadrupeds. The strong and peculiar interest which the Elephant possesses above all other beasts arises in fact not so much from his gigantic bulk and immense muscular power, as from the high opinion usually entertained of those intellectual qualities with which he has long been supposed to be preeminently endowed, and which have rendered him a theme of exaggerated encomium to the careless observer, while even in some philosophic minds they have furnished the groundwork on which perverted ingenuity has built up theory after theory as baseless and imaginary as the foundation on which they have been made to rest, the reason and reflection of a brute.

It is on this account that we feel it incumbent upon us, notwithstanding all that has been written on the subject, to dwell with some little detail on the natural history of this singular animal; but we shall nevertheless endeavour to compress our observations within the smallest possible compass. We shall commence as usual with his zoological characters, and shall then take a glance at his habits, such as they appear in a pure state of nature, unfettered by any laws but those of necessity, and uncontrolled except by the inevitable influence of the circumstances in which he is placed. And lastly we shall view him when under the control of man, and reduced to that half-domesticated condition to which even his stubborn nature is bowed by the application of those means which man alone can employ, and by which he maintains his ascendancy as undisputed lord of the creation over the mightiest even more effectually than over the meanest of its works.

The Elephants belong to the Pachydermatous order, in which they constitute a family readily distinguishable from the other enormous beasts which form part of it, the Hippopotamus and the Rhinoceros, by a combination of characters of the most remarkable description. To the immense size and clumsy figure of the two last named animals, which indeed they commonly surpass in both those particulars, they add the following distinctive zoological characters. Their teeth consist of two formidable tusks, which, occupying the place of the incisors of the upper jaw, project forwards in a nearly horizontal direction, generally with a slight curvature upwards; and of one or occasionally two cheek teeth of considerable magnitude on each side of each jaw, formed of vertical layers of bony matter surrounded by enamel, and connected together by a third substance called cortical. These latter are not, as in almost all the other Mammalia, renewed for one only time and at a certain age by the growth of others to supply their places from the cavity of the jaw beneath them; but, on the contrary, are pushed forwards by the advance of those which are destined to replace them from behind, and are renewed, according to the statement of Mr. Corse, no less than eight times at different periods of the animal’s existence. On each successive change the number of laminæ of which they are composed is increased, the earliest not offering more than four, while the later ones frequently exceed twenty; and it is in consequence of the new teeth generally making their appearance for some time prior to the total failure of their predecessors that their number occasionally appears to be double its proper and more usual amount. The tusks on the contrary admit but of a single displacement and renewal; the first or milk pair seldom exceeding two inches in length, and falling out between the first and second year. The permanent ones which succeed are much larger and more powerful in the adult male than in the female, and not unfrequently project as much as two feet. They are well known as furnishing one of the most beautiful and ornamental productions which the animal kingdom affords, as well as a valuable article of commerce, in the pure and polished ivory of which they are formed. They have been known to weigh as much as one hundred and fifty pounds, but their usual average is from fifty to seventy.

The ears of the Elephant are large, not elevated like those of other quadrupeds so as to form a kind of trumpet for the reception of sound, but flattened down upon the side of the head, and forming a broad and uninterruptedly expanded surface. His eyes, remarkably small in proportion to his bulk, are sheltered above by a cluster of long hairs, which, with a few others scattered over the head and still more rarely on the body, and a kind of brush at the extremity of the tail, constitute the only covering, if covering it may be called, with which he is provided. His skin in fact is throughout nearly destitute of hair; but in return it is, as in the rest of the order, of excessive thickness and extreme tenacity, insomuch as to be capable of repelling a common musket ball, which scarcely makes the slightest impression upon its surface. His feet are enveloped by a large hoof of a callous and almost horny consistence, and are divided, in the skeleton at least, into five toes, the extremities only of which, rendered obvious by the nails by which they are surmounted, are externally visible. On the hind feet the number of apparent toes varies from three to four.
