%X As a supplement to work reported earlier (Thomas, Svenson, and Brown 1956), in which the receiver gain of a P'f recording equipment was systematically changed from record to record, a similar experiment has been devised in which the power radiated by the transmitting aerial is systematically changed, thus altering the "signal-to-noise" ratio at the receiver. This should and does give results differing from those formerly obtained.
