It is said that the Gaur will not live in a state of captivity; even when taken very young, the calf soon droops and dies. The bull-calf of the first year is called, by the natives, Purorah; the female, Pareeah; and when full-grown the cow is called Gourin. Gaurs associate in herds consisting usually of from ten to twenty animals. So numerous are they on Myn Pat, that, in one day hunting, the party computed that not less than eighty had passed through the station occupied by the sportsmen. The Gaurs browse on the leaves and tender shoots of trees and shrubs, and also graze on the banks of the streams. During the cold season they remain concealed in the _saul_ forests, but in hot weather come out to feed in the green vallies and lawns, which occur on the mountain of Myn Pat. They show no disposition to wallow in mire or swamps, like the Buffalo; a habit, indeed, which the sleekness of their skins renders not at all probable. The period of gestation is said to be twelve months, and they bring forth usually in August." To the preceding observations of Dr. Traill, I have to add the important fact (which of itself will be sufficient to constitute a specific difference between the Gaur and the Gayal), namely, that in the skeleton of the Gaur there are only thirteen pairs of ribs, whilst the skeleton of the Gayal possesses fourteen pairs. This fact I have ascertained from an examination of both the skeletons; that of the Gaur in the museum of the Zoological Society, and that of the Gayal, in the possession of Mr. Bartlett, Russell Street, Covent Garden. (See p. 68.) The skeleton of the Gaur just referred to, strikingly confirms Dr. Traill's account of the elevated dorsal ridge of this animal; several of the dorsal vertebrae measuring, with their spinous processes, upwards of seventeen inches each, the longest being twenty inches and a half. The Gaur, from which this skeleton was taken, was killed at Nicecond, November 8, 1843. There is another fine specimen of the skull and horns of the Gaur, in the Museum of the Zoological Society, taken from an animal killed by Lieut. Nelson, on the Neilsburry Hills, Salem district. This animal measured nineteen hands and half an inch at the shoulder. Dimensions of the Figure in the British Museum:-- Ft. In.
