The great spirals, with their enormous radial velocities and insensible proper motions, apparently lie outside our Solar system.
The outstanding feature, however, is the possibility that the velocity-distance relation may represent the de Sitter effect, and hence that numerical data may be introduced into discussions of the general curvature of space.
