In this paper we extend Chandrasekhar and von Neumann's analysis of
the statistics of the gravitational field to systems in which
particles (e.g. stars, galaxies) are not homogeneously distributed. We
derive a distribution function giving
the joint probability that a test particle is subject to a force
