The pressure at any point of a fluid at rest under gravity varies as its depth. Thus, the head of each foot of water produces a pressure of 0 ' 433 Ibs. to the square in. We learn from a series of experiments such as those undertaken by the " Challenger " expedition that the pressure varies from 14 ' 7 Ibs. to the square inch on the surface to 28 Ibs. at a depth of 32 ft., and so on in proportion to great depths; also the weight of a unit volume of water remains constant at any depth, as for practical purposes this fluid is incompressible. 3. The buoyancy of a floating body in water is the upward support given by the water. 4. The weight of water displaced is equal to the product of its volume into the weight of water per unit volume. 5. The amount of water displaced has a volume equal in weight to the weight of the floating body. 6. Eeserve of buoyancy is the volume of water-tight compartments that are above the water plane when vessel is at rest. 7. The centre of gravity of any system involving weight is the point at which we may consider the whole system to be concentrated, and through which point the weight acts vertically downwards; this applies also to bodies immersed partially or wholly in a fluid. Exploring voyage of H.M.S. " Challenger," 1873. 8. The centre of buoyancy of any vessel floating freely at rest, either on the surface or wholly submersed, is the centre of gravity of the displaced fluid. Any type of submarine boat must essentially be designed to have sufficient buoyancy to enable the crew to pass freely in or out, also to allow indispensable stores being carried. Mr. Holland laid down that about 8 per cent. of the total displacement should be out of water. This gava hi.<
