PAGE PREFACE IN the A.B.C. of Hydrodynamics 1 I have dealt chiefly with the fundamentals of the subject especially examining the assumptions on which the mathematical treatment was based. In the present little work I have developed the subject by practical application to definite cases of resis- tance especially examining and studying the experi- mental work carried out by Dubuat and Duchemin, to whose memory I have dedicated this little book. It is unfortunate that Dubuats Principes dHydraulique is at present so exceedingly unpopular I am afraid that this is largely due to the author having found out experi- mentally, that the resistance experienced by a body moving in water, was less than that which it exerted when it was at rest in a flowing stream. This has caused his experi- ments to be considered as unreliable. Since the foregoing may tend to prejudice the reader against this distinguished mans work, I will quote what Sir George Stokes said about him. In his exceedingly interesting papers On the Motion of Pendulums we read I come now to the experiments of Dubuat, which are contained in an excellent work of his entitled Principes dHydraulique . . . . Dubuat justly remarks that the time of oscillation of a pendulum osci2lating in a fEuid is greater than it would bein a vacuum, not only on account of the buoy- .ancy of the id, which diminishes the moving force, but also on account of the mass of the aid, which.must be regarded as accowq5anying the pendulum in its motion and even determined experimentally the mass of uid which must be regarded as carried by the oscillating body in the case of spheres and of several other solids...
