It is not built quite like your long-voyage steamers, but its lines are sufficiently long, and its curves prolonged enough, to allow the water to slide off easily, and oppose no obstacle to its passage.

These two dimensions enable you to obtain by a simple calculation the surface and cubic contents of the Nautilus.

Its area measures 6,032 feet; and its contents about 1,500 cubic yards; that is to say, when completely immersed it displaces 50,000 feet of water, or weighs 1,500 tons.
"When I made the plans for this submarine vessel, I meant that nine-tenths should be submerged: consequently it ought only to displace nine-tenths of its bulk, that is to say, only to weigh that number of tons.

I ought not, therefore, to have exceeded that weight, constructing it on the aforesaid dimensions.
"The Nautilus is composed of two hulls, one inside, the other outside, joined by T-shaped irons, which render it very strong.

Indeed, owing to this cellular arrangement it resists like a block, as if it were solid.
