Quasi-simultaneous photometric and polarimetric observations of T Tau and RY Tau show that the proper polarization of these stars barises in the visual region in their gaseous emitting envelopes. The polarization of T Tau shows cyclic variations with a period of 5h18. That of RY has two different modes of variation at brightnesses V > 11m and V < 11m; it is possibly connected with the suspected binary nature of this star.
