The general uses of sponge, arising from its ready absorption of fluids, and distension by moisture, are well known, and of great importance. It is collected from rocks, in water five or six fathoms deep, chiefly by divers, who, after much practice, become extremely expert in obtaining it. When first taken from the sea, it has a strong and fishy smell, of which it is divested by being washed in clear water. No other preparation than this is requisite previously to its being packed up for exportation and sale. The growth of sponge is so rapid that it is frequently found in perfection on rocks from which, only two years before, it had been entirely cleared. It is principally imported into this country from the Levant. Sponge is sometimes used by surgeons for the dilating of wounds; and, as it adheres strongly to the mouths of wounded vessels, it is occasionally applied as a styptic to prevent their bleeding. Sponge burnt in a close earthen or iron vessel, and then reduced to powder, is sometimes used as a medicine. INDEX TO THE THIRD VOLUME. ---- A. Albicore. See Thunny.
