BS>This investigation is restricted to primary cosmic rays of nuclear charges equal to or greater than ten at the geomagnetic latitude of 41 degrees north. Data were obtained from thick emulsions exposed at high altitudes over Texas. The flux, extrapolated to the top of the atmosphere, was found to be 2.65 plus or minus 0.3 particles/m/sup 2/ sec sterad. The distribution histogram for the charge spectrum is included. The attenuation meam free paths for three groups were 28.5 plus or minus 26, respectively. (auth)
