First printing of Wilson's paper in which he investigated the mobility of ions in flames, studying the electrical discharge in rarified gases...and following J.J. Thomson, made an attempt to determine the charge of the electron by using the cloud chamber. The experiment, in which he observed the fall of the condensation drops in the vertical electric fiels and its absence, was a forerunner of the more precise technique developed by Robert Millikan. (DSB 18, supplement II, p. 992).
