1. The problem which is investigated in some details in the following paper is the wave resistance of a vertical post in a uniform stream. The horizontal section of the post is of ship-shape form and the lines are varied in a certain manner while keeping the area of the section constant. A direct study of ship waves as a three-dimensional problem for a ship of finite dimensions has not yet been attacked by the method of an equivalent distribution of pressure on the surface of the water. Some advance has also been made in the case of submerged bodies; I have shown previously how to calculate the wave resistance of a body whose form is derive by combining the stream-lines of a uniform current with certain distributions of sources and sinks, under the limitation that the dimensions of the body are small compared with its depth. On the other hand Michell in an extremely interesting paper, gave a general expression for wave resistance; but it suffers from a serious limitation, in that the surface of the ship must be everywhere inclined at only a small angle to its vertical median plane.
