The statistical characteristics of a homogeneous sample of 108 Abell clusters are analyzed. Estimates are offered for a number of mass and motion parameters according to two theoretical models of perturbing gravitational fields. For the average peculiar velocity of the center of mass motion of the Abell clusters, an estimate of 610 (+ or - 750) km/s is obtained. From this result an upper limit of the average mass of the Abell clusters 1.6 (+ or - 2.4) x 10 to the 5th solar mass is derived, under the assumption that peculiar motion is due to the excess of neighbors with respect to a uniform background. The lower limit for average mass was 2.4 (+ or 2.9) x 10 to the 14th/hr (omega to the 0.4th) solar mass, assuming that the peculiar velocity results from mutual acceleration with the nearest neighbor.
