The energy distribution function for globular clusters in the Galaxy is calculated using the inversion procedure first suggested by Eddington. If the halo mass distribution is of the form M(H) = alpha times r exp 1.21, then the observed data on the velocity dispersion of F-clusters can be explained, resulting in an enclosed mass of 4.3 x 10 to the 11th solar masses within a galactocentric radius of 33 kpc.
