The data and conclusions of Sonneborn et al. (1987) concerning the Omega Ori are analyzed using the general formulation of continuum polarization in Be-star envelopes of Brown and McLean (1977). The ratio of variability amplitude in narrow UV lines to that in optical polarization and the time dependence of these amplitudes are examined. Model-equation-derived data are found to support the conclusions that: (1) the line-profile variability in the UV line does not correlate with the visual continuum polarization; (2) the visual color and continuum fluxes correspond with the polarization; and (3) the H-alpha variations are weakly related to the polarization.
