Abstract
The Sydney data on extensive air showers in the energy range 10(17) to 10(19) eV have been re-examined from the standpoint of endeavouring t o determine the energy spectrum of the various masses of particles pre sent in the cosmic ray beam, idealized as a simple mixture of protons and iron nuclei. The analysis suggests that the ratio of iron nuclei t o protons increases with energy in the range under consideration, bein g congruent-to 1.0 at 10(18) eV and congruent-to 2.0 at 10(19) eV.
