Abstract
ABOUT a year ago, attention was directed to a new mathematical theory of radio-interaction1 which, contradicting the original mathematical theory2, leads to the important conclusion that abnormally large impressed modulations may be caused by waves the frequencies of which are nearly equal to the local gyro-frequency (that is, the frequency of gyration of a free electron in the earth's magnetic field). This conclusion was strikingly confirmed in the course of experiments3 carried out in March 1937.
