• Using the tubes with two photocathodes the abnormalities of photocurrents were studied. The abnormalities of the tubes were conspicuous when one of the cathodes was isolated. These abnormal effects could be well explained from the results obtained when the potential of the isolated cathode was varied and current characteristics of the tubes were measured at various wave length of light. The effects were considered to be due to the voltage changes of the isolated cathode resulting from its own photoemission and secondary emission caused by the incidence of light. Photoelectric materials of usual photo-tubes adhering to the undesired portion of the inner surfaces can be analogously considered to the isolated cathodes of the tubes.
