The following discussion of the experimental determination of the charge e of an electron may prove interesting inasmuch as the conditions of the experiment were in many respects more favorable than those of previous attempts. As is generally known, determinations of e have been made by J.J. Thomson and H.A. Wilson at the Cavendish-laboratory, England. Their methods were quite different, although both obtained their data from observations of ionized clouds produced by the rapid expansion of supersaturated air in a fog chamber.
