THE BAT has the body of a mouse, and the wings of a bird. It has an enormous mouth, and large ears, which are of a kind of membrane, thin and almost transparent. The pinions of its wings are furnished with hooks, by which it hangs to trees or the crevices in old walls during the day, a great number of them together, as they only fly at night. The wings of the Bat are very large; those of the Great Bat measuring fifteen inches across. It feeds on insects of various kinds, particularly on cockchafers and other winged beetles, part of which, however, it always throws away. A female Bat that was caught, and kept in a cage, ate meat when it was given to her in little bits, and lapped water like a cat. She was very particular in keeping herself clean, using her hind feet like a comb, and parting her fur so as to make a straight line down the back. Her wings she cleaned by thrusting her nose into the folds, and shaking them. She had a young one born in the cage. It was blind, and quite destitute of hair, and its mother wrapped it in the membrane of her wing, pressing it so closely to her breast, that no one could see her suckle it. The next day the poor mother died, and the little one was found alive, hanging to her breast. It was fed with milk from a sponge, but only lived about a week. [Illustration: THE PIPISTRELLE. (_Vespertilio Pipistrellus._)] THIS little creature, which is only an inch and a half in length, appears to be the commonest of all Bats in most parts of Britain. It usually resides in cracks and cavities in old brick walls and in sheltered corners about houses, and at the approach of evening quits its retreat, and flies about capturing the gnats and other small twilight-loving insects on which it feeds. [Illustration: THE LONG-EARED BAT. (_Vespertilio_ or _Plecotus auritus_.)] THE LONG-EARED BAT, which is not uncommon in many parts of our country, is remarkable for the large size of its ears, which are nearly as long as its little mouse-like body, and composed of a membrane so delicate as to be almost transparent. In front of the concave part of each of these enormous ears there is a slender, pointed membrane, which gives the little creature a most singular appearance when reposing; for the great membranous ears are then folded up, and carefully stowed away under the wings, whilst these pointed lobes, being of a stronger substance, still project from the head, and look like a pair of little horns. The Long-eared Bat seems to be one of the most interesting and amiable species of its tribe; it may be easily tamed, and, indeed, exhibits great confidence from the first moment of its capture. When several are kept together they will play in an awkward manner, which is very diverting, and will soon learn to take their insect food not only from the hand, but even from the lips of their owner.
