Broad-band circular polarization measurements for 32 white dwarfs are presented, part of a continuing program to assess the magnetic field distribution and stellar parameters of magnetic white dwarfs. None of the stars discussed here represent statistically significant detections, though a few are marginal, and one in particular (LP777-1) deserves closer study. The null results for cool degenerates include the very low luminosity stars LP701-29, LP131-66, and Ross 193B (VB11), and support the hypothesis that the temperature distribution of magnetic stars is not signficantly different from the distribution of all white dwarfs. G35-26, a likely low-field case with Zeeman-split lines, does not show significant continuum circular polarization.
