Toy, Edgerton, and Vick have recently shown that the photoelectric effect in silver bromide is due to ultraviolet light of wavelength less than λ 2800A. Since the photographic effect extends to λ 5000A they concluded that there is no relation between the photoelectric and the photographic effects in silver bromide. Before this article appeared, the writer had obtained approximately the same result with silver bromide formed by fuming the surface of a silver plate. Our data was obtained by the use of more sensitive apparatus than that employed by the above named investigators. In order to prevent deterioration of the silver bromide the plate was kept in complete darkness until the time of exposure by which measurements were made.
