and has acquired the name of wool, to the long, flowing, and glossy locks of the Esquimaux, between which there are many gradations. Precisely parallel varieties are ascertained to arise in the same race of animals. Those of the domestic kind “vary from each other in size much more than individuals the most different in stature among mankind.” The small Welsh cattle compared with the large flocks of the southern counties in England; or the Shetland ponies with the tall-backed mares of Flanders; the bantam breed with the large English fowls, are well known examples. More striking instances are mentioned by naturalists. In the isles of the Celebes, a race of buffaloes is said to exist, which is of the size of a common sheep; and Pennant has described a variety of the horse in Ceylon, not more than thirty inches in height. The swine of Cuba, imported into that island from Europe, have become double the height and magnitude of the stock from which they were derived. The disproportionate arm of the Negro and leg of the Hindoo meet an exact parallel in the swine of Normandy, the hind-quarters of which are so out of keeping with the fore, that the back forms an inclined plane to the head; and as the head itself partakes of the same direction, the snout is but a little removed from the ground. Among domesticated animals, no species afford more striking specimens of modification in structure than the hog tribe. The external forms which the race has assumed surpass in monstrosity the most extraordinary diversities of the human frame. “Swine,” observes Blumenbach, “in some countries have degenerated into races which, in singularity, far exceed every thing that has been found strange in bodily variety among the human race. Swine with solid hoofs were known to the ancients, and large breeds of them are found in Hungary and Sweden. In like manner the European swine first carried by the Spaniards in 1509 to the island of Cuba—at that time celebrated for its pearl-fishery—degenerated into a monstrous race, with toes that were half a span in length.” The texture of the skin of several species of animals is different in a wild and in a domesticated condition; and the character of the hair exhibits analogous variations to that of the tribes of mankind. In the instance of a neglected flock of sheep, the fine wool is soon succeeded by a coarser kind, and the breed approximates to the argali, or wild sheep of Siberia, the original stock, which are covered with hair. The covering of the goat and dog displays the same variety. Thus, the several external distinctions from each other which the nations of men develop, must be admitted to be plainly compatible with their forming a single species, when distinctions of a parallel nature, but more numerous and singular, have arisen within the limits of a species in the inferior animal creation. It may be difficult, nay impossible, to explain the phenomena of
