Rutherford and Geiger, 3 by moving a photographic film past the illuminated fiber of a string-electrometer, obtained a photograph of the fiber showing deflection of the fiber caused by the discharges between an electrode and the surrounding chamber when ionization by collision took place in the chamber upon the entrance of individual aparticles into the chamber. This has been the only method described thus far for obtaining a record of a-particles. The method described in this paper makes it possible to get a record on a chronograph paper, of individual a-particles or 8-particles or of 7-ray pulses (), which may then be studied at ones convenience and the count made with a greater accuracy than is obtainable with the visual or audible methods. The accuracy of the method was tested both for a-particles and 3-particles. The applicability of the law of probability to the emission of 3-particles was proved and some experiments were made with 7-rays. The Self-reg1strat1on Method. In the visual method the counting chamber is connected to a fairly high positive voltage (about 2, 000 volts) and the needle electrode is connected to earth through a very high resistance (ink on paper) and also to the fiber of the string electrometer or to the gold leaves of the other electrometers above mentioned. In the audible method a telephone receiver is placed between the needle and earth, if the discharge current in the counting chamber is sufficiently large to actuate the diaphragm of the telephone receiver; or else, it is placed in the plate-filament circuit of an audion amplifier, the needle electrode being connected directly to the grid or to earth through the primary of a. . .
