Abstract
THIS book is a revised and enlarged edition of Prof. Millikan‘s book "Electrons" which appeared in 1935, and was itself based on his celebrated work "The Electron" (1917), which in its day occupied a unique position in the literature of atomic physics. It is pleasing to note that the early chapters of the new edition still conform closely to the text of "The Electron", for they contain one of the few accurate accounts in English of the early history of the measurement of the atomic charge. The first fifteen chapters are essentially the same in the new edition as in the 1936 edition, except for emendations to the text, the most important of which is to the value of the atomic charge as obtained from observations of falling drops. This now appears as e=4·807 X 10-10 E.S.U. It is also stated that the value e=4·803 X 10-10 E.S.U. obtained from a comparison of X-ray diffraction from a ruled grating and a crystal lattice is the more precise.
