Abstract
DR. L. R. MAXWELL, in NATURE of Dec. 29, 1928, gives an account of experiments intended to show the influence of cosmic rays on the speed of radioactive disintegration of polonium. According to Perrin, the radiation may be regarded as a possible cause of radioactive changes. The detailed study of cosmic rays, carried out lately by numerous investigators, and the determination of their probable wavelengths, combined with the ideas of Perrin, involuntarily led us to think that the cosmic rays may be the real cause of radioactive processes. The frequency of cosmic rays is of such magnitude that their quanta ought to be sufficient to disintegrate the nucleus.
