First the adiabatic radiative perturbations associated with the neutrino perturbations of cluster size are compared with the upper limit of anisotropy of the cosmic background radiation, and it is found that the scenario is worth noticing, in which galaxies first form from primordial entropy perturbations and later clusters of galaxies form by the clustering process. Next the nonlinear growth of entropy perturbations of galaxy size is numerically analyzed, and the amplitudes of the initial perturbations necessary for the formation of galaxies at the epochs z>__~3 are derived. The growth in the Lemaitre universe also is examined. It is concluded that this scenario is possible.
