The evolution of model systems consisting of some 10,000 gravitating mass points is investigated numerically for initial configurations approximating homogeneous oblate ellipsoids of revolution. The results obtained show that: (1) quasi-homogeneous nonrotating ellipsoids tend to evolve toward a common density profile and a common velocity-dispersion profile; (2) the final configuration is flattened; (3) rapid relaxation divides the particles in a system into two or more groups with respect to energy; and (4) if all the points of a system fall nearly simultaneously toward the center, both highly flattened and spherical systems will evolve toward a quasi-steady state with a density distribution that differs substantially from that observed in rich clusters of galaxies and in elliptical galaxies.
