The first and second velocity moments of the stellar distribution function were calculated numerically for the triaxial model of Schwarzschild (1979) in two extreme cases: first, in such a way that the mean motions everywhere canceled, and second, such that they took on their maximum permitted value. The ratio of kinetic energy in mean motions to potential energy is about 3% in the maximal case. The pressure is roughly isotropic in the center but becomes increasingly anisotropic in the outer regions, in such a way that the greatest dispersion at any point tends to lie along a radial axis. The radial dispersion peaks near the center, falling off at both large and small radii. Projected rotation and velocity dispersion curves are presented for various orientations.
