destined tree, they mount it with much greater ease than when they moved upon the plain. They fall to with famished appetite, and, as before, destroy the very source that supplies them."

How far these may be considered as the unfinished productions of nature, I will not take upon me to determine : if we measure their happiness by our sensations, nothing, it is certain, can be more miserable ; but it is probable, considered with regard to themselves, they may have some stores of comfort unknown to us, which may set them upon a level with some other inferior ranks of the creation; if a part of their life be exposed to pain and labour, it is compensated by a larger portion of plenty, indolence, and safety. In fact, they are formed very differently from all other quadrupeds, and it is probable they have different enjoyments. Like birds they have but one common vent for the purposes of propagation, excrement, and urine. Like the tortoise, which they resemble in the slowness of their motion, they continue to live some time after their nobler parts are wounded, or even taken away. They bear the marks of all those homely-formed animals that, like rade machines, are not easily discomposed.

Its note,(8) according to Kircher, is an ascending and descending hexachord, which it utters only by night; its look is so piteous as to move compassion; it is also accompanied with tears, that dissuade everybody from injuring so wretched a being. Its abstinence from food is remarkably powerful: one that had fastened itself by its feet to a pole, and was so suspended across two beams, remained forty days without meat, drink, or sleep; the strength of its feet is so great that whatsoever it seizes on cannot possibly be freed from its claws. A dog was let loose at the above-mentioned animal, taken from the pole; after some time the sloth laid hold of the dog with its feet, and held him four days, till he perished with hunger.

THE JERBOA.

This animal as little resembles a quadruped as that which has been described in a former chapter.* If we should suppose a bird divested of its feathers, and walking upon its legs, it might give us some idea of its figure. It has four feet, indeed, but in running or resting it never makes use of any but the hinder. The number of legs, however, do not much contribute to any animal's speed; and the jerboa, though properly, speaking, furnished but with two, is one of the swiftest creatures in the world.

The jerboa is not above the size of a large rat, and its head is sloped

(The Jerboa.) somewhat in the manner of a rabbit; the teeth, also, are formed like those of the rat kind, there being two cutting teeth in each jaw; it bas a very long tail, tufted at the end; the head, the back, and sides are covered with large, ash-coloured, soft bair; the breast and belly are whitish ; but what most deserves our attention, in the formation of this little animal, is the legs: the fore legs are not an inch long, with four claws and a thumb upon each, while the binder legs are two inches and a quarter, and exactly resemble those of a bird, there being but three toes, the middlemost of which is longest.

The jerboa is found in Egpyt, Barbary, Palestine, and the deserts between Busserah and Aleppo : its hind legs, as was said before, are only used in running, while the fore paws, like those of a squirrel, grasp its food, and in some measure perform the office of hands. It is often seen by travellers as they pass along the deserts, crossing their way, and jumping six or eight feet at every bound, and going so swiftly that scarce any other quadruped is able to overtake them. They are a lively, harmless race of animals, living entirely upon vegetables, and burrowing like rabbits in the ground. Pendant tells us of two that were lately brought to London, that burrowed almost through the brick wall of the room where they were kept: they came out of their hole at night for food,

As to the external conformation, the is extremely abundant in Barbary, in Higher ierboas exhibit some relations with the kan. and Lower Egypt, and Syria, and again in garoos. The form of the body is the same the more northern climates, situated between in general. The hinder limbs are likewise the Tanais and the Volga ; the other occupyfive or six times stronger than the fore. In ing an immense space in Siberia and the both genera the tail is very long ; the ears north part of Russia, from Syria to the Eastelongated and pointed, and the eyes very ern Ocean, and as far as the northern parts of arge and round.

and, when canght, were much fatter and sleeker than when confined to their burrows. A variety of this animal is found also in Siberia and Circassia, and is, most probably, common enough over all Asia. They are more expert diggers than even the rabbit itself; and when pursued for a long time, if they cannot escape by their swiftness, they try to make a hole instantly in the ground, in which they often bury themselves deep enough to find security before their pnrsuers come up. Their burrows in some places are so thick as to be dangerous to travellers, the horses perpetually falling into them. It is a provident little animal, and lays up for the winter. It cuts grass in heaps of a foot square, which when dried it carries into its burrow, therewith to serve it for food, or to keep its young warm during the rigours of the winter.

But of all animals of this kind, that which was first discovered and described by Sir Joseph Banks is the most extraordinary. He calls it the kangaroo; an:! though from its general outline, and the most striking, peculiarities of its figure, it greatly resembles the jerboa, yet it entirely differs, if we consider its size, or those minute distinctions which direct the makers of systems in assorting the general ranks of nature.*

The largest of the jerboa kind which are to be found in the ancient continent do not exceed the size of a rabbit. The kangaroo of New Holland, where it is only to be found, is often known to weigh above sixty pounds, and must consequently be as large as a sheep. Although the skin of that which was stuffed and brought home by Sir Joseph Banks was not much above the size of a hare, yet it was greatly superior to any of the jerboa kind that have been hitherto known, and very different in many particulars. The snout of the jerboa, as has been said, is short and round, that of the new-discovered animal long and slender : the teeth also entirely differ; for, as the jerboa has but two cutting teeth in each jaw, making four in all, this animal, besides its cutting teeth, has four canine teeth also. But what makes a more striking peculiarity, is the formation of its lower jaw, which, as the ingenious discoverer snpposes, is divided into two parts, which open and shut like a pair of scissors, and cut grass, probably this animal's principal food. The head, neck, and shoulders are very small in proportion to the other parts of the body; the tail is nearly as long as the body, thick near the rump, and tapering towards the end; the skin is covered with a short fur, excepting the head and the ears, which bear a slight resemblance to those of the hare. We are not told, however, from the formation of its stomach, to what class of quadrupeds it belongs. From its eating grass, which it has been seen to do, one would be apt to rank it among the ruminant animals; but from the canine teeth which it is found to have, we may on the other hand suppose it to bear some relation to the carnivorous. Upon the whole, however, it can be classed with none more properly than with animals of the jerboa kind, as its hind legs are so much longer than the fore: it moves, also, precisely in the same manner, taking great bounds of ten or twelve feet at a time, and thus sometimes escaping even the fleetest greyhound with which Sir Joseph Banks pursued it. One of them that was killed proved to be good food; a second,

• THE GIGANTIC KANGAROO. — Buffon, asia has given an additional support to this whose only errors were those of genus, clearly opinion of Buffon. The species of animals perceived that every continent, in its animal there discovered have not only no affinity with productions, presented the appearance of an those of the other continents, but, in fact, especial creation ; but he gave a universality to belong for the most part to genera altogether this proposition of which it is not altogether different. Such are those mammalia which susceptible. It is, nevertheless, true, even the natives of New Holland call kangaroo ; at the prestnt day, within certain limits.

which weighed eighty-four pounds, and was not yet come to its full growth, was found to be much inferior. *

With this last described and last discovered animal I shall conclude the history of quadrupeds, wbich of all parts of natural knowledge seems to have been described the most accurately. As these, from their figure as well as their saga. city, bear the nearest resemblance to man, and from their uses or enmities are the most respectable parts of the inferior creation, so it was his interest and his pleasure to make himself acquainted with their history. It is probable, therefore, that time, which enlarges the sphere of our knowledge in other parts of learning, can add but very little to this. The addition of a new quadruped to the catalogue already known is of no small consequence, and happens but seldom; for the number of all is so few, that wherever a new one is found it becomes an object worthy our best attention.t

*The CHINCHILLA.-An ani. mai soinewhat resembling the jerboa, but which bas not yet been classified by naturalists, is the chinchilla.Notwithstanding the extensive traffic carried on in the skins of this animal, little was correctly known regarding it until 1830. earliest account of the chin. chilla with which we have met is contained in Father Joseph Acosta's Natural and Moral His. tory of the East and West Indies, published at Barcelona, in Spanish, in the year 1591.
