THE body of the Great Ant-eater is covered with exceedingly coarse and shaggy hair. Its head is very long and slender, and the mouth but just large enough to admit its tongue, which is cylindrical, nearly two feet in length, and lies folded double within it. The tail is of enormous size, and covered with long black hair, somewhat like the tail of a horse. The whole length of the animal, from the end of the snout to the tip of the tail, is sometimes seven or eight feet. Its food consists principally of ants, which it obtains in the following manner:--When it comes to an ant-hill, it scratches it up with its long claws, and then unfolds its slender tongue, which much resembles an enormously long worm. This being covered with a glutinous matter or saliva, the ants adhere to it in great numbers: these it swallows alive, repeating the operation till no more are to be caught. He also tears up the nests of wood-lice, which it in like manner discovers; but should it meet with little success in its pursuit of food, it is able to fast for a considerable time without inconvenience. The motions of the Ant-eater are in general very slow. It swims, however, over great rivers with ease; and, on these occasions, its tail is always thrown over its back. With this extraordinary member, when asleep, or during heavy showers of rain, the animal is also said to cover its back; but at other times he carries it extended behind him. The Ant-eater is a native of South America. [Illustration: THE DUCK-BILLED PLATYPUS, OR WATER MOLE. (_Ornithorhynchus paradoxus._)] THIS extraordinary creature has the bill and webbed feet of a duck, united to the body of a mole. It is a native of Australia, where it is found on the banks of rivers, in the sides of which it burrows and forms its nest. It feeds on aquatic insects and small molluscous animals, always, however, rejecting the shells of the latter, after crushing them in its mouth, so as to extract the body. A number of these animals are always found together; but it is very difficult to watch their habits, as their sense of hearing is so acute, that they disappear at the slightest noise, plunging into the water, in which they swim so low, that they only look like a mass of weeds floating on the surface. When the animal feeds, he plunges his beak into the mud, just like a duck; and appears to be equally at home on land and in water. Two young ones that were kept for some time at Sydney, by Mr. Bennet, were very fond of rolling themselves up like a hedgehog, in the form of balls. They often slept in this position, and “awful little growls” issued from them when disturbed. They were fed with worms, and bread and milk; but captivity did not seem to agree with them, and they soon died. They dressed their fur by combing it with their feet, and pecking at it with their beaks, seeming to take great delight in keeping it smooth and clean.
