Results of investigations concerning a theory of meson production based on the two fire balls models are reported. Calculations concerning the reaction cross section in N-nucleus and nucleus-nucleus collisions are also reported along with experimental results on meson production and fragmentation induced by heavy cosmic-ray primaries. (J.R.D.) Two values for the flux of the hydrogen component in the primary cosmic radiation have been measured. The first one was over Guam in the Marianas Islands, geomagnetic latitude lambda = 0 deg . The value of the flux was found to be (123 plus or minus 12) hydrogen nuclei/m/sup 2/ sterad sec. The second measurement was made over Texas, lambda = 41 deg N., and the value found was (530 plus or minus 53) hydrogen nuclei/m/sup 2/ sterad sec. The detectors in both cases were stacks of nuclear emulsion exposed at high altitude. The results obtained in this experiment are in good agreement with the values obtained by the others using electronic counters flown at the same geomagnetic latitudes. (auth)
