When thoroughly warmed up, our bat will soon start on a tour of inspection of his cage. He steps rapidly from one wire to another, sometimes hooking on with all five toes, but generally with four or three. There seems to be little power in these toes, except of remaining bent in a hooked position; for when our bat stops and draws up one foot to scratch the head, the claws are merely jerked through the fur by motions of the whole leg, not by individual movements of the separate toes. In this motion we notice, for the first time, that the legs and feet grow in a kind of "spread eagle" position, making the knees point backward, in the same direction as the elbows.
We must stop a moment to admire the beautiful soft fur, a golden brown in colour, with part of the back nearly black. The tiny inverted face is full of expression, the bead-like eyes gleaming brightly from out of their furry bed. The small moist nostrils are constantly wrinkling and sniffling, and the large size of the alert ears shows how much their owner depends upon them for information. If we suddenly move up closer to the wires, the bat opens both wings owl-like, in a most threatening manner; but if we make still more hostile motions the creature retreats as hastily as it can, changing its method of progress to an all-fours, sloth-like gait, the long free thumb of each hand grasping wire after wire and doing most of the leverage, the hind legs following passively.
When at what he judges a safe distance he again hangs pendent, bending his head back to look earnestly at us. Soon the half-opened wings are closed and brought close to the shoulders, and in this, the usual resting position, the large claws of the thumbs rest on the breast in little furrows which they have worn in the fur.
Soon drowsiness comes on and a long elaborate yawn is given, showing the many small needle-like teeth and the broad red tongue, which curls outward to a surprising length. Then comes the most curious process of all. Drawing up one leg, the little creature deliberately wraps one hand with its clinging web around the leg and under the arms, and then draws the other wing straight across the body, holds it there a moment, while it takes a last look in all directions. Then lifting its fingers slightly, it bends its head and wraps all in the full-spread web. It is most ludicrously like a tragedian, acting the death scene in "Julius Cæsar," and it loses nothing in repetition; for each time the little animal thus draws its winding sheet about its body, one is forced to smile as he thinks of the absurd resemblance.
