occurrence. It has moreover been noticed in many species of birds. The present species of Antelope is spread over the whole of the Peninsula of Hindoostan and a part of Persia; but it is questionable whether it has been found in Africa, as is commonly asserted. They are said to bound with apparent ease over a distance of from twenty-five to thirty feet, and mounting to the height of ten or twelve. It is consequently useless to attempt to chase them in the common mode with hounds; and their pursuit is restricted to the higher nobility, who employ for the purpose either hawks, who pounce upon their quarry and detain it until the dogs can come up, or Chetahs, who attack them by surprise in the manner before described. The elegant Albino now in the Tower was brought from Bombay by Captain Dalrymple of the Vansittart, and remained for a considerable time at Sand Pit Gate, where it was an especial favourite with his Majesty, as well on account of the gentleness of its disposition, as for its rarity and beauty. It bears its confinement in the Menagerie with perfect resignation, and is remarkable for the mildness and tranquillity of its deportment. [Illustration] [Illustration] THE AFRICAN SHEEP. _OVIS ARIES._ LINN.--Var. _GUINEENSIS._ In characterizing the present genus, were we to look solely at the animal such as we have it daily before our eyes, the distinction between it and all the other Ruminants is too striking to be for a moment mistaken. But the insensible gradations which connect this familiar denizen of our downs and pastures with the untamed native of the desert and the precipice, and the close affinity which subsists between the latter and the goats, render it almost impossible to isolate them by any satisfactory characters. On the present occasion we shall content ourselves with observing that the sheep may generally be distinguished by the direction of their horns, by the elevation of their profile, and by their want of beard: characters neither essential nor infallible, but the best that can be offered. The variety figured over leaf is in one of the many intermediate stages between unreclaimed barbarism and complete domestication. It is an awkward looking creature, high on the legs, narrow in the loins, and covered with a rough and shaggy coat. The back and sides are nearly black; the shoulders reddish brown; and the posterior part of the body, the haunches, the hind legs, and the tail, white; as are also the ears, which are rather large, the nose, and a spot over each eye. The horns, although the specimen is a male, are remarkably small, and enclose the ears within their curve. If the ears are freed from their confinement, the animal becomes very uneasy, and never rests until he has succeeded in replacing them, which he cannot accomplish without considerable difficulty. He was presented to the Menagerie by Lord Liverpool about six years ago, and is extremely mild in his temper. [Illustration] [Illustration]
