the lower jaw it has a formidable row of large teeth of conical shape, forty-two in number. It has, however, none in the upper jaw; but instead, there are holes into which fit the points of those in the lower. These teeth are blunt, and are not used for biting or mastication, but merely to keep in the food which has entered its mouth. This food is chiefly the _Squid_ or _Sepia octopus_, known also by the name of the cuttle-fish. In the South-Seas they are of enormous size, and, with their long feelers or arms growing out of their heads, are sufficiently strong to hold a man under the water and to kill him. The sperm whale, however, swallows a variety of other fish. It catches them, not by swimming after them, but by opening wide its mouth and letting its prey swim into it! We will suppose ourselves looking down that vast mouth, as the lower jaw hangs perpendicularly to the belly; incapable it seems of moving. The interior of the throat is very large--capable of swallowing a man; the tongue is very small and delicate, and of a pure white colour; so are the teeth, which glisten brilliantly; and so is the whole interior. Fish are particularly attracted by their white appearance. They take it, perhaps, to be some marble hall erected for their accommodation; so in they swim, big and little squid equally beguiled! How the whale's mouth must water when he feels a fine huge juicy octopus playing about his tongue! Up goes the lower jaw like a trap-door, and cephalapods, small and large, find their bright marble palace turned into a dark, black prison, from which there is no return; for, giving a turn with his tongue, he gulps them all down with a smack which must make old Ocean resound!
