Comparison of the intensities of He, C + O, and Fe + Ni cosmic ray nuclei as measured on balloon flights in Canada and Argentina at several energy levels between about 1 and 50 GeV per nucleon. A re-analysis of previous data and those of Juliusson et al. (1972) and Smith et al. (in the press) is carried out. The differences in the spectra of these nuclei are discussed.

The functional form of the modulation for the 11-year variation changed abruptly after the Forbush decrease of June 8, 1969. This change in the 11-year modulation suggests that this Forbush decrease was an integral part of the 11-year variation. Some details of the change as observed by neutron monitors and by spacecraft at low energies are discussed.
