Accession No.1372


"The object of my invention is a torpedo-boat which has the advantage of the submarine boat in its absolute protection from injury by ample submergence beneath the waves, and yet like the surface torpedo-boat can be navigated from a conning-tower above the w2ater and is always in communication with the atmosphere, so that air may always be had for ventilation and for combustion, thus permitting the use of the most efficient motive power."
