5. The _adimain_, or great sheep of Senegal and India, which are covered with hair more or less short or coarse according to the heat of the climate. All these sheep are only varieties of the same species, and certainly would produce with each other, since we know from experience that the he goat, whose species is further distant, copulates with our ewes. But though these five or six races of domestic sheep are all varieties of the same species, entirely produced by the difference of climate, treatment, and food, yet none of them appear to be the primitive stock from whence the others sprung; nor is there any of them strong or swift enough either to resist, or avoid, carnivorous animals, by flight. They all equally need care and protection, and must all, therefore, be looked upon as degenerate races, formed by the hands of man, and multiplied for his use. At the same that he fed, cultivated, and increased these domestic races, he neglected, hunted, and destroyed the wild breed, which being stronger and less tractable, would, consequently, be more troublesome, and less useful; they are, therefore, only to be met with in small numbers, and in thinly inhabited places, where they can support themselves. In the mountains of Greece, in the islands of Cyprus, Sardinia, and Corsica, and in the desarts of Tartary, the animal, which we call the _muflon_ (_fig. 139._), is still to be found, and which in my opinion is the primitive stock of all the varieties of sheep; he lives in a state of nature, and subsists and multiplies without the help of man; he resembles the several kinds of domestic sheep more than any other wild animal; he is more lively, stronger, and swifter, than any of them; his head, forehead, eyes, and face, are like the ram's; he resembles him also in the form of the horns, and in the whole habit of the body; in short, he produces with the domestic sheep, which alone is sufficient to demonstrate that he is of the same species, and the primitive stock of the different breeds. The only difference betwixt the muflon and our sheep is, that the first is covered with hair instead of wool; but we have already observed, that even in domestic sheep the wool is not an essential character, but a production of temperate climates, since in hot countries these same sheep have no wool, and are all covered with hair; and that, in cold countries, their wool is as coarse as hair. Hence it is not astonishing that the primitive wild sheep, who must have endured cold and heat, have lived and increased without shelter in the woods and deserts should not be covered with wool, which he would soon be deprived of among the thickets; and its nature would, in a short time, be changed by the action of the air, and in temperature of the seasons. Besides, when a he-goat copulates with a domestic ewe, the produce is a kind of muflon, for the lamb is covered with hair, and is not a barren mule, but a mongrel, which returns towards the original
