The CHEIROPTERA (Bat tribe, fig. 71), have fore feet so modified as to serve as wings, with which they fly with tolerable swiftness, producing a peculiar flapping sound. These wings are formed by a membrane which is stretched out between the fingers, which are exceedingly elongated, and which reaches from the fore feet to the hind feet. The Bat tribe all feed upon insects, especially moths; they rest in the day time head downwards, clinging to rough places by means of the claws of their hind feet, coming out at night to seek their food; their sight, which is very quick, enabling them to see their prey when almost dark. Some of the larger species of this tribe, inhabiting America, are called Vampire Bats, they live by sucking the blood of various animals, such as cattle and horses, thereby inflicting dangerous wounds.

Mona (Cercopithecus mona); 4. Howler (Mycetes); 5. Spider (Ateles).] 11. The QUADRUMANA (fig. 72), so called from their hind and fore feet both having thumbs, and being developed into hands, includes the Monkeys; they may be divided into two tribes, those inhabiting the Old World (Simiidæ), and those inhabiting the New (Cebidæ), these include what were formerly called Apes, Baboons, &c. These animals approach the most nearly to the form of the human being, the Chimpanzee being considered the nearest in formation to Man; there are, however, many very broad distinctions between the two, especially in the foot and head. The Quadrumana are very clever, but their actions seem to have more meaning in them than they in reality possess, owing to the resemblance of these creatures to the human being. There are many surprising accounts of these beings, such as their arming themselves with sticks and stones to defend themselves; but no act of reason has ever yet been perceived in them, nor any tendency towards improvement, except that which has been given them by Man. "The Monkey who had seen the world," and went home and taught his companions, is a fable in both senses of the word. The Monkey tribe are formed to pass their lives in the trees among the branches, their hands being formed to suit this kind of life. None of them walk well, but when they are among the branches, swinging themselves from bough to bough, few creatures are more active; their food is fruit and nuts of all kinds. The Chimpanzee, certainly, is the nearest approach to Man in the lower animals, and walks better in an upright position than does the Ourang-outang, whose whole life is spent in the trees, while the Chimpanzee often inhabits holes in the earth and rocks. In the "Penny Cyclopædia" is the following account of one, by Captain Payne:--
