Abstract
We find definite evidence that a new band of rays which we interpret as helium annihilation rays does come in vertically at about the predicted latitude. We present a discussion of the possible composite character of the so-called silicon annihilation band and of the so-called oxygen annihilation band. We then bring forward an explanation of the cause of our large and already reported variability in the cosmic-ray intensities found in high altitude electroscope flights at Bismarck, Omaha, and Oklahoma City. We also make a new and more accurate determination of the value of the field sensitive and the non-field sensitive components of the incoming cosmic rays.
