"Swine transported from Europe to America, since the discovery of the western continent by the Spaniards in the fourteenth century, and wandering at large in the vast forests of the New World, and feeding on wild fruits, have resumed the manner of existence which belonged to the original stock. Their appearance nearly resembles that of the wild boar. Their ears have become erect; their heads are larger, and the foreheads vaulted at the upper part; their colour has lost the variety found in the domestic breeds. The wild hogs of the American forests are uniformly black. The hog which inhabits the high mountains of Paramos bears a striking resemblance to the wild boar of France. His skin is covered with a thick fur, often somewhat crisp, beneath which is found, in some individuals, a species of wool. From excessive cold and defect of nourishment, the hog of that region is of small and stunted figure. In some warm parts of America, the swine are not uniformly black, as above described, but red, like the young pecari. At Melgara and other places, there are some which are not entirely black, but have a white band under the belly reaching up to the back; they are termed _cinchados_. The restoration of the original character of the wild boar in a race descended from domesticated swine, removes all reason for doubt, if any had really existed, as to the identity of the stock; and we may safely proceed to compare the physical characters of these races, as varieties which have arisen in one species. The restoration of one uniform black colour, and the change of thin sparse hair and bristles for a thick fur with a covering of wool, are facts that must be noticed in the observations of M. Roulin. The difference in the shape of the head between the wild and domestic hog of America, is very remarkable. Blumenbach long ago pointed out the great difference between the cranium of our swine and that of the primitive wild boar. He remarked that this difference is quite equal to that which has been observed between the skull of the Negro and the European. 'Those persons,' he says, 'who have no opportunity of verifying the fact, have only need to cast their eyes on the figure which Daubenton has given of both the former. I shall pass over,' he adds, 'the lesser varieties of breeds which may be found among swine, as among men, and only mention that I have been assured by M. Sobzer, that the peculiarity of having the bone of the leg remarkably long, which in the human kind is observed among the Hindoos, has been remarked with regard to swine in Normandy. They stand very long on their hind legs; their back, therefore, is highest at the rump, forming a kind of inclined plane; and the head proceeds in the same
