Varying much in size and colour : with or without horns : wool coarse or fine, long or short, according to the breed, sometimes approaching the quality of hair: tail short, or reaching below the knees.
Probably not originally indigenous. Primitive stock supposed to be the Argali* (Ovis Ammon, Gmel)., which is found in a wild state in the mountainous parts of Asia. Period of gestation about five months. Produces one or two at a birth, rarely more. The two middle incisors fall at the end of the first year, and are replaced by others; the next in succession at about the age of two and a half: by the end of the third year, or soon after, all have been renewed, and the individual is said to be full-mouthed.
