 THE WILL IN NATURE.

ant-bear, for instance, is not only armed with long claws on its fore-feet, in order to break into the nests of the white ant, but also with a prolonged cylindrical muzzle, in order to penetrate into them, with a small mouth and a long, threadlike tongue, covered with a glutinous slime, which it inserts into the white ants' nests and then withdraws covered with the insects that adhere to it: on the other hand it has no teeth, because it does not want them. Who can fail to see that the ant-bear's form stands in the same relation to the white ant's, as an act of the will to its motive? The contradiction between the powerful fore-feet and long, strong, curved claws of the ant-bear and its complete lack of teeth, is at the same time so extraordinary, that if the earth ever undergoes a fresh transformation, the newly arising race of rational beings will find it an insoluble enigma, if white ants are unknown to them. The necks of birds, as of quadrupeds, are generally as long as their legs, to enable them to reach down to the ground where they pick up their food; but those of aquatic birds are often a good deal longer, because they have to fetch up their nourishment from under the water while swimming. 1 Moor-fowl have exceedingly long legs, to enable them to wade without drowning or wetting their bodies, and a correspondingly long neck and beak, this last being more or less strong, according to the things (reptiles, fishes or worms) which have to be crushed; and the intestines of these animals are invariably adapted likewise to this end. On the other hand, moor-fowl are provided neither with talons, like birds of prey, nor with web-feet,

1 I have seen (Zooplastic Cabinet 1860) a humming-bird (colibri) with a beak as long as the whole bird, head and tail included. This bird must certainly have had to fetch out its food from a considerable depth, were it only from the calyx of a flower (Cuvier, Anatomie Comparée vol. iv. p. 374); otherwise it would not have given itself the luxury, or submitted to the encumbrance, of such a beak.
