Abstract
THE problems dealt with in these two books have a certain similarity in that in each case the ship, or to use a more general term, the machine or contrivance, has to navigate wholely immersed in the medium for which it is designed, and this similarity is not disturbed by the condition that the submersible may have also to navigate on the upper surface of the sea, for the balloon, and especially the flying machine, equally has to start and to finish at the lower surface of the atmosphere.
