    • Abstract


      An investigation of the diurnal variation of the cosmic ray intensity with different counter arrangements has been made. The results obtained are similar to those reported by previous investigators, except in the case of the meson intensity measured with the method of shower anticoincidences. Here a semidiurnal variation which is positively correlated with the semidiurnal variation of pressure has been found. An explanation in terms of the meson decay and the nature of the daily atmospheric oscillations has been suggested. The possibility of gaining knowledge about the altitude of the meson forming layer has been mentioned.
