had ceased to suck and afterwards were reared by us.  In what space of time it reaches such a growth as to be abandoned entirely by the mother, we are ignorant.  It is born blind, totally bald, the orifice of the ear closed and only just the centre of the mouth open, but a black score, denoting what is hereafter to form the dimension of the mouth, is marked very distinctly on each side of the opening.  At its birth, the kangaroo (notwithstanding it weighs when full grown 200 pounds) is not so large as a half-grown mouse.  I brought some with me to England even less, which I took from the pouches of the old ones.  This phenomenon is so striking and so contrary to the general laws of nature, that an opinion has been started that the animal is brought forth not by the pudenda, but descends from the belly into the pouch by one of the teats, which are there deposited.  On this difficulty as I can throw no light, I shall hazard no conjecture.  It may, however, be necessary to observe that the teats are several inches long and capable of great dilatation.  And here I beg leave to correct an error which crept into my former publication wherein I asserted that, “the teats of the kangaroo never exceed two in number.”  They sometimes, though rarely, amount to four.  There is great reason to believe that they are slow of growth and live many years.  This animal has a clavicle, or collar-bone, similar to that of the human body.  The general colour of the kangaroo is very like that of the ass, but varieties exist.  Its shape and figure are well known by the plates which have been given of it.  The elegance of the ear is particularly deserving of admiration.  This far exceeds the ear of the hare in quickness of sense and is so flexible as to admit of being turned by the animal nearly quite round the head, doubtless for the purpose of informing the creature of the approach of its enemies, as it is of a timid nature, and poorly furnished with means of defence; though when compelled to resist, it tears furiously with its forepaws, and strikes forward very hard with its hind legs.  Notwithstanding its unfavourable conformation for such a purpose, its swims strongly; but never takes to the water unless so hard pressed by its pursuers as to be left without all other refuge.  The noise they make is a faint bleat, querulous, but not easy to describe.  They are sociable animals and unite in droves, sometimes to the number of fifty or sixty together; when they are seen playful and feeding on grass, which alone forms their food.  At such time they move gently about like all other quadrupeds, on all fours; but at the slightest noise they spring up on their hind legs and sit erect, listening to what it may proceed from, and if it increases they bound off on those legs only, the fore ones at the same time being carried close to the breast like the paws of a monkey; and the tail stretched out, acts as a rudder on a ship.  In drinking, the kangaroo laps.  It is remarkable that they are never found in a fat state, being invariably lean.  Of the flesh we always eat with avidity, but in Europe it would not be reckoned a delicacy.  A rank flavour forms the principal objection to it.  The tail is accounted the most delicious part, when stewed.
