The intensities of air showers S/sub 1/ and S/sub 2/, with particle densities of 45m/sup -2/ and 180m/sup -2/ respectively, are measured as functions of altitude from sea level to 6.4 km. At the lower half of the atmosphere, the observed intensities show an exponential decrease with the atmospheric depth, and the obseryed absorption coefficients are 120 plus or minus 4 g - cm/sup -2/ of air for S/sub 1/ and 136 plus or minus 10 g - cm/sup -2/ of air for S/sub 2/. The zenith angle dependence of air showers is also observed by the same apparatus in terms of the ratio of counting rates of the horizontal counters to those of the vertical counters. The observed ratio at 6.4 km is 2.43 plus or minus 0.29 for S/sub 1/, and 2.3 plus or minus 0.7 for S/ sub 2/. This result is consistent with the altitude curve, and the comparison between the altitude curve and the zenith angle distribution is discussed. (auth)
