I must be allowed to give a somewhat more lengthened description than I have bestowed on other animals, to the Felidæ, or Cat-tribe, because the same characters serve for all; size and colour being almost the only difference among those of which I shall treat. Grace and strength are their universal attributes, the latter lying chiefly in the fore parts of their frames; such as their paws, legs, shoulders, neck and jaws; the former in their arched and rounded form, and the extreme suppleness of their joints. Their muzzle is short and round, some of their teeth are of enormous size and strength, their sight is very acute both by night and day; their eyes are set obliquely in the head, and always glare in the dark; and sometimes by day when they are in a rage. It is only in the smaller tribes that the pupil is vertically linear, when the full light causes it to contract. The ears are large, and the sense of hearing much developed. Their smell is not equally perfect, and the roughness of their tongue shews, that their taste cannot be very delicate. This roughness is caused by the horny papillæ, or small projections, with points directed backwards, which cover the tongue, and enable it to lick the flesh from the bones of their food. They have long bristles on each side of the mouth, which form the most sensitive organs of touch; each bristle being inserted in a bed of glands under the skin, communicating with a nerve. The claws of the Felidæ are extremely strong, sharp, and crooked; and all four-feet are furnished with them, five before, and four behind; and the most effective system of muscular contrivance not only gives such force to the fore-paws, that a blow from one of these will fracture a man's skull, but keeps these claws from touching the ground, and enables the animal to draw them back into a sheath. In aid of this, the sole of the foot, and each of the toes, has a soft, elastic pad, or cushion under it, on which they walk, and as they never set the heel to the ground, their footsteps are noiseless, unless they choose them to be otherwise. It is with their formidable claws, and still more formidable teeth, that they tear their prey to pieces.
