A peculiarity in the digestive organs of some animals causes all those who possess it to be thrown together into one large order, by naturalists. They have no front teeth, except in the lower jaw, and in place of them, the upper jaw is provided with a bony pad. A very few have canine teeth, and their grinders are marked with double crescents. They have two hoofs, but as the inside edge of these is flattened, they look as if they had only one cleft down the middle, the foot underneath is provided with elastic pads, connecting the toes together, and extruding beyond them at the sides. These cushions at each step expand, support the After they have taken their food, these Ruminantia, as they are called, lie down, and remain in a state of complete repose, in order to chew it a second time; and the process is thus accomplished: they have four stomachs, the first is called the paunch, and is the largest of all; into it descend the grass, herbs, and leaves, when first cropped and imperfectly masticated. Thence the mass goes into the second stomach, or honeycomb, so named, because its structure gives it the appearance of that substance: it is small and globular, and by means of its cells, squeezes the food into little balls, which are thrown up into the mouth of the animal, to receive a second mastication, called "chewing the cud." After this has been effected, it descends into the third stomach, or the feck, which looks something like the several leaves of a book; lastly it goes into the fourth stomach, which is merely wrinkled. It is in this that real digestion takes place; all the previous labour having been but a mere preparation for it, and indicated by the name of the order, taken from a Latin word, signifying "to chew over." It would seem impossible for any animals to be more useful to man than the dog or the horse, yet these Ruminantia are still more precious to him, for while they serve him as beasts of burden, or The Camels and Dromedaries, which come first before me, are confined but to a small portion of the earth's surface; they, however, in their more confined sphere afford incalculable benefits. Without them we should not be able to traverse those large plains of sand, which lie between the different countries of Africa, and also of south-western Asia. Their gaunt and angular form does not class them among the beauties to which I have alluded; and the only pretensions which their outward appearance can present for praise, is their admirable adaptation for the offices which they have to perform. Their full, upper lip is cleft, their neck is long, their eyes prominent and shaded with eye-lashes, their nostrils are like slits, which they can close at pleasure; their body has one or two humps on it, their legs have callous pads upon them, their feet are large and spreading, and their hair hangs loosely upon them in patches. That long, upper lip, however, when the hot blast of the desert almost The camel has two humps, the dromedary one; the last is the lightest and the swiftest, and is generally chosen for riding, while the former carries the burdens. High saddles are placed on their backs; and it requires either to be used to them, or to be particularly careful not to be half killed at starting. The rider places himself in the saddle while the animals are kneeling; and, when they raise their hind legs, which they do first of all, they send the unprepared traveller forwards, and his breath is almost taken out of him by the blow which he receives upon his chest; then as they get The load of a camel is about 800 lbs., and their usual pace nearly three miles an hour; but at this |
