The Amphitrite is 259 feet 6 inches long ; 55 feet 10inches beam ; and 14 feet 6 inches draught, with a dis-placement of 3,990 tons. The hull is built of iron andconsists of an inner and an outer shell, spaced 3 feetapart and tied together by the ribs or transverse frames,and by the longitudinal girders of the vessel. The in-tersection of the frames and girders, whose top andbottom flanges are riveted to the inner and outer shells, forms a series of separate, watertight compartments, or cells, as they are called, which will serve to localizethe effect of the blow of a torpedo, and confine thewater to the damaged portion of the ship.

Themain deck is flush throughout the ship, except whereit is broken by the superstructure and the barbettesand turrets of the big guns. It is formed of two layersof plate steel, giving a total thickness of 1% inches. Be-neath this protective deck and behind the shelter of the continuous belt of solid steel are located theengines and boilers, the working mechanism of the tur-rets, and the stores of powder and shell. The turrets are formed of 7*4 inch Harvey steel, andtheir bottom edge revolves just within and near the top edge of the bar-bettes, which may be de-scribed as circular forts
