The Puruk sheep of Ladusk, in the Himalaya mountains, is, as described by Mr Moorecraft, in the _Transactions of the Asiatic Society_, in respect to the varied nature of its food, a most remarkable animal. "The Puruk sheep, if permitted, thrusts its head into the cooking pot, picks up crumbs, is eager to drink the remains of a cup of broth, and examine the hand of its master for barley, flour, or a cleanly picked bone, which it disdains not to nibble; a leaf of lettuce, a peeling of turnip, the skin of the apricot, give a luxury; and the industry is indefatigable with which this animal detects, and appropriates substances, so minute and uninviting as would be unseen and neglected by ordinary sheep; perhaps the dog of the cottager is not so completely domesticated as it is." That Mr Moorecraft is correct in this statement of its omnivorous propensities, there cannot be the slightest doubt, as any farmer can testify from what he has seen of lambs reared by children for amusement. The celebrated John Hunter showed, that a pigeon might be made to live on flesh, and that its stomach became adapted to the nature of this food: and I have somewhere read of a sheep, which, after being long on ship-board, and accustomed, from scarcity of vegetables, to an animal diet, could never after be prevailed upon to take to grass. Nor need these circumstances excite surprise, since the food of every living creature is, for a certain period at the commencement of existence, limited to such as is purely animal. But to keep to our subject. Those in the habit of opening the stomachs of sheep, must have remarked the eroded appearance which the inner coat occasionally presents. This phenomenon is owing to the action of the gastric juice, which, if competent to turn at once from the food with which it is mingled to attack the texture which has secreted it, will also be, during life, capable of digesting with tolerable ease, such dead animal matter as may be brought into contact with it. In regard to vegetable food, they will, when necessary, devour such as is even of an acrid nature, and calculated to poison any animals but themselves. Thunberg, while in Southern Africa, frequently noticed sheep eating, with impunity, the _Mortimia acris_, the _Rhus lucidum_, and the _Lycium afrum_, which are all of a poisonous nature; and, in this country, hemlock is known to be quite innocuous to sheep. What is poison to one animal often constitutes a wholesome food for others, and that which will, when given in immediate large doses, destroy an animal, will, when taken in a gradually-increasing allowance, prove extremely salutary.
