Elephants are often spoken of as "Ungulates," and classed by naturalists with the hoofed animals (the odd toed tapirs, rhinoceroses, and horses, and the even-toed pigs, camel, cattle, and deer). But there is not much to say in defence of such an association. The elephants have, as a matter of fact, not got hoofs, and they have five toes on each foot. The five toes of the front foot have each a nail, whilst usually only four toes of the hind foot have nails. A speciality of the elephant is the great circular pad of thick skin overlying fat and fibrous tissue, which forms the sole of the foot and bears the animal's enormous weight. This buffer-like development of the foot existed in some great extinct mammals (the Dinoceras family, of North America), but is altogether different from the support given by a horse's hoof or the paired shoe-like hoofs of great cattle or the three rather elegant hoofed toes of the rhinoceros. The Indian elephant likes good, solid ground to walk on, and when he finds himself in a boggy place will seize any large objects (preferably big branches of trees) and throw them under his feet to prevent himself sinking in. Occasionally he will remove the stranger who is riding on his back and make use of him in this way. The circumference of the African elephant's fore-foot is found by hunters to be half the animal's height at the shoulder, and is regarded as furnishing a trustworthy indication of his stature. The legs of the elephant differ from those of more familiar large animals in the fact that the ankle and the wrist (the so-called knee of the horse's foreleg) are not far above the sole of the foot (resembling man's joints in this respect), whilst the true knee-joint (called "the stifle" in horses)--instead of being, as in horses, high up, close against the body, strongly flexed even when at rest, and obscured by the skin--is far below the body, free and obvious enough. In fact, the elephant keeps the thigh and the upper arm perpendicular and in line with the lower segment of the limb when he is standing, so that the legs are pillar-like. But he bends the joints amply when in quick movement. The hind legs seen in action resemble, in the proportions of thigh, foreleg, and foot, and the bending at the knee and ankle, very closely those of a man walking on "all fours." The elephant as known in Europe more than 300 years ago was rarely seen in free movement. He was kept chained up in his stall, resting on his straight, pillar-like legs and their pad-like feet. And with that curious avidity for the marvellous which characterized serious writers in those days to the exclusion of any desire or attempt to ascertain the truth, it was coolly asserted, and then commonly believed, that the elephant could not bend his legs. Shakespeare--who, of course, is merely using a common belief of his time as a chance illustration of human character--makes Ulysses say (referring to his own stiffness of
