Abstract
The purpose of this note is to remove misconceptions due to erroneous statements regarding the determination of the elementary electronic charge by the oil-drop method. It is emphasized that the existence of an elemental charge is directly proved by the multiple relationship shown to exist between successive charges on each test particle; that the unitary character of electricity is not pre-supposed even in determining the absolute value; and that the method used by Sexl in determining the radius of the droplet is not essentially new. Recent photo-electric work of Hake and of Wasser is discussed briefly.
