    (where e is the electronic charge) the volume v occupied by the ] : ) 1 2 electrons in the unit quantity transferred will be ms where n is the number of electrons per unit volume. WV and Bee and n=|pdo=5e0/o = 578 log. 3! where N, and JN, are the number of electrons per unit volume in the two conductors. This result was given by Sir J. J. Thom- son. The phenomena just described have been dealt with to illus- trate the nature of the electron theory of matter and the kind of progress which has already been made. In many directions, however, the theory is as yet only tentative, and the underlying assumptions still under discussion. In particular until the actual arrangement of electrons in the atomic systems is more accurately determined, and until more is known as to the nature of the action which causes energy to be radiated and absorbed in definite “quanta,” the principles of the subject cannot be said to have been definitely laid down. For this reason, as well as for the reason that the mathematical analysis involved is often of the most intricate kind, we shall not pursue the subject further in the present volume.
