inches long, white, and spotted at the larger end.

We are unwilling to interrupt the course of our narrative by disquisitions on subjects of natural history, and, therefore, relegate to a note the following particulars about the dugong. This strange mammal belongs to a genus of the family Manatidae, or Herbivorous Cetacea. The species of which a member was discovered by our castaways, is the Halicore Indicus, or dugong of the Indian Archipelago; and, as we have said, is never found very far from land. Its dentition resembles, in some respects, that of the elephant; and from the structure of its digestible organs it can eat only vegetable food; that is, the algae, or weeds, growing on submarine rocks in shallow water. When it comes to the surface to breathe, it utters a peculiar cry, like the lowing of a cow. Its length, when full-grown, is said to be twenty feet, but few individuals seem to exceed twelve feet. In its general appearance it is very much like the manatee, or manatus, which haunts the mouths of the great South American rivers.

Strictly speaking, the Singapore oyster is a gigantic species of Clam, (Tridacna).

To these particulars we may add that the durion (Durio zibethinus) belongs to the natural family of Sterculiaceae, of the same sub-order (Bombaceae) as the silk-cotton tree. It grows to a great stature; its leaves are like those of the cherry, and its pale yellow flowers hang in large bunches. Each tree yields about two hundred fruit in a year. The fruit contains ten to twelve seeds, as large as pigeons’ eggs, and these, when roasted, are as good as, and taste very much like, roasted chestnuts.
