Abstract
S. E. FORBUSH1 has noted a systematic decrease of cosmic ray ionization at Cheltenham, U.S.A., and Huancayo, Peru, simultaneous with a decrease of the earth's horizontal magnetic force (H.F.), during magnetic storms of April 1937. V. F. Hess and A. Demmelmair2 have confirmed the existence and world-wide character of the cosmic ray decrease by observations on the Hafelekar near Innsbruck. They agree with Forbush in concluding that the study of these cosmic ray changes during magnetic storms will give valuable information on the spectrum of the cosmic radiation.
