Africa is almost the only country that does not produce the stag, but it produces the chameleon¹, which, however, is much more commonly met with in India. Its figure and size are that of a lizard², only that its legs are straight and longer. Its sides unite under its belly³, as in fishes, and its spine⁴ projects in a similar manner. Its muzzle⁵ is not unlike the snout of a small hog⁶, so far as it can be in so small an animal. Its tail is very long, and becomes smaller towards the end, coiling up in folds like that of the viper⁷. It has hooked claws, and a slow movement like that of the tortoise; its body is rough like that of the crocodile; its eyes are deep sunk in the orbits, placed very near each other, very large, and of the same color as the body. It never closes them, and when the animal looks round, it does so, not by the motion of the pupil, but of the white of the eye. It always holds the head upright and the mouth open, and is the only animal which receives nourishment⁸ neither by meat nor drink, nor anything else, but from the air alone.[105] Towards the end of the dog-days it is fierce, but at other times quite harmless. The nature of its color, too, is very remarkable⁹, for it is continually changing; its eyes, its tail, and its whole body always assuming the color of whatever object is nearest, with the exception of white and red.[106] After death, it becomes of a 98 pale color. It has a little flesh about the head, the jaws¹⁰, and the root of the tail, but none whatever on the rest of the body. It has no blood whatever, except in the heart and about the eyes, and its entrails are without a spleen. It
