"The sheep is one of the most anciently domesticated animals, and it is one in which great varieties display themselves. It has been long believed, and this appears to have been the opinion of Baron Cuvier, that all the breeds of tamed sheep are descended either from the argali of Siberia, or from the moufloun or musmon of Barbary. This is at present doubted by most naturalists. There seems, however, to be no reason for believing that the domestic breeds belong to more than one species, though they differ much in different countries. In Europe, the breeds of sheep vary much in stature, in the texture of their wool, the number and shape of their horns, which are in some large, in some small, in others wanting to the female, or altogether absent from the breed. The most important varieties in Europe are the Spanish breeds, some with fine, others with crisp wool, in which the rams have long spiral horns; the English breeds, which differ greatly in size and in the quality of the wool; and, in the southern parts of Russia, the long-tailed breed. The breeds of sheep in India and in Africa are remarkable for the length of their legs, a very convex forehead, and pendant ears; these also have long tails. Their covering is not wool, but a smooth hair. In the northern parts of Europe and Asia the sheep have short tails. The breeds spread through Persia, Tartary, and China, have their tails transformed into a double spherical mass of fat. The sheep of Syria and Barbary, on the other hand, have long tails, but likewise loaded with a mass of fat. In both of these varieties of the sheep the ears are pendant, the horns of the rams large, and those of the ewes and lambs of moderate size, and the body is covered with wool, mixed more or less with hair.
