The Fall and Saslaw (1976) equation for the growth of pair correlations in an expanding universe of identical self-gravitating point masses, which is correlation-free at some initial time, is presently generalized to the case of a multicomponent system of particles with different masses. Each of the species contained is characterized by a Maxwellian distribution at the same temperature. Even a very small contamination of heavy masses can increase the total correlational energy density, thereby decreasing the time scale for the evolution of interesting structure by orders of magnitude. By appropriately choosing relative concentrations and masses, it becomes possible to arrange for the correlational energy density to be dominated by interactions between light and heavy particles rather than by interactions between members of either single species.
