The 22 nebulae for which distances are not available can be treated in two ways. First, the mean distance of the group derived from the mean apparent magnitudes can be compared with the mean of the velocities corrected for solar motion. The result, 745 km./sec. for a distance of 1.4 X 106 parsecs, falls between the two previous solutions and indicates a value for K of 530 as against the proposed value, 500 km./sec.
