Abstract:
    We present simultaneous UBV linear polarization measurements for 361
    A- and F-type stars with accurate colour excess and distance
    determination. These stars are distributed in 35 Kapteyn's Selected
    Areas, covering the third and fourth quadrants of the galactic plane
    (|b|≤30°). The obtained polarization and the known colour excess
    are compared. An analysis of the polarization distribution as a
    function of the stellar distance is also performed.
