A comprehensive study is made of the polarization eclipse of V444 Cyg using an extensive data set of multicolor linear polarization observations obtained with emphasis on the eclipse of the WR star by the O-star companion. A model is introduced with an improved treatment of the various occultation effects. A comparison of the model with the observations yields estimates of the O and WR star radii (8.5 +/- 1 and less than 4 solar radii, respectively) as well as of the WR mass-loss rate (0.75 x 10 exp -5 solar mass/yr).
