Statistical mass-to-light ratios are found for spiral and irregular galaxies, and E and S0 galaxies, using 57 multiple systems including 43 pairs. The results are consistent with those of the earlier study by Page. Preliminary conclusions point out the great uncertainties in such mass-to-light ratios due to inaccurate magnitudes and relative radial velocities. The derived masses are relatively insensitive to the choice of the distribution function of projected separations.
