To the singularities already related we shall add some others. The fat of the hog differs from that of almost every other quadruped, not only in its consistence and quality, but its position in the body of the animal. The fat of man, and those animals which have no suet, such as the dog, horse, &c. is pretty equally mixed with the flesh; the suet of the sheep, goat, deer, &c. is found only at the extremities of the flesh; but the fat of the hog is neither mixed with the flesh nor collected at its extremities, but covers the animal all over, and forms a thick, distinct, and continued layer between the flesh and the skin. This peculiarity also attends the whale, and other cetaceous animals. A still greater singularity is, that the hog never sheds any of his cutting teeth, like man, the horse, ox, sheep, &c. but they continue to grow during life. He has six cutting teeth in the under jaw, and a corresponding number in the upper, but, by an irregularity, of which there is not another example in Nature, the bottom ones are of a very different form from the upper, for instead of being incisive and sharp, the latter are long, cylindrical, blunt at the points, and form an angle almost even with the upper jaw, so that their extremities apply to each other very obliquely. It is only the hog, and two or three other species of animals, which have the canine teeth very long; they differ from other teeth by coming out of the mouth, and growing during their whole lives. In the elephant, and sea-cow, they are cylindrical, and some feet in length; in the wild boar, and male hog, they are partly bent in the form of a circle, and I have seen them from nine to ten inches long; they are deep in the socket, and, like those of the elephant, have a cavity at the superior extremity; but the elephant and sea-cow have these tusks only in the upper jaw, and are without canine teeth in the under; while the male hog, and wild boar, have them in both jaws, and those of the under are the most useful to the animal; they are also the most dangerous, as it is with the lower tusks the wild boar wounds those he attacks. The sow, wild sow, and the hog which is cut, have these canine teeth in the under jaw, but they do not grow like those of the boar, and scarcely appear out of the mouth. Beside these sixteen teeth, that is twelve incisive and four canine, they have twenty-eight grinders, which make forty-four in the whole. The wild boar, (_fig. 29._) has the tusks larger, the snout stronger, and the head longer than the domestic hog, (_fig. 28._) his feet are always larger, his toes more separated, and his bristles always black.
