In this note we point out a solution of Vlasov equation for mass points with identical mass m moving in the self-consistent averaged gravitational field, which may be of interest in discussing evolutions of irregularities due to gravitation.1) It represents a spherical isothermal distribution in the presence .of the universal expansion or contraction in the Newtonian approximation. With obvious notations we have a set of equations: where Since the general discussion of these equations are well
