Besides its perfume, the Skunk has yet another claim to careful avoidance: its bite has been known in many cases to produce hydrophobia, in a form quite indistinguishable, according to an American surgeon, Dr. Janeway, from that induced by the bite of a rabid Dog. An allied species, the Little Striped Skunk,[185] is less than a foot long, and the tail is shorter than the body. The fur is black, and marked with numerous white stripes and spots. It is found in the southern part of the United States, and is said to be readily capable of domestication, proving very serviceable as a Mouser. Of course, under these circumstances, the glands are removed while the animal is young. The White-backed Skunk[186] is the South American form of the genus. It occurs throughout that Continent as well as in Mexico and the south-western portions of the United States. It is much larger than the northern species, attaining a length of from eighteen inches to two feet, and is further distinguished by its short white tail, which does not exceed nine or ten inches in length, its pig-like snout projecting a full inch beyond the mouth, and its white back sometimes marked by a median black stripe. The rest of the fur is, as usual, black. Our friend, Mr. Purdie, whose acquaintance with the Skunk in South America has been of the most practical kind, assures us that when about to discharge its secretion, the animal invariably faces round, so as to look its enemy full in the face, throws its tail over its back, and allows the breeze to carry the fluid in the desired direction. This method of discharge seems highly unaccountable, and difficult to reconcile with the anatomical facts; but it would be certainly going too far to say that it is impossible. Dr. Coues, who has repeatedly observed the North American Skunk, states that the animal invariably turns its back to its intended victim.
