| Abstract: | The spatial velocities of 24 globular clusters have been determined. Correlations among the velocities of the clusters, their
positions in the Galaxy, and their metallicity indices are investigated. The mean velocity ellipsoid is determined, which
proves to be nearly spherical. Clusters belonging to different groups of blue horizontal-branch stars in accordance with Mironov,
Rastorguev, and Samus’ are considered separately.
