We know several infrared objects showing large intrinsic polarization (FORBES 1967, APPENZELLER and O’DELL 1967, KRUSZEWSKI 1968, SERKOWSKI 1969, SHAWL 1969, SHAWL and ZELLNER 1970, KRUSZEWSKI 1971, DYCK, FORBES and SHAWL 1971).

In the following discussion I shall speak about the broad category of infrared stars which consists of reddest and coolest giants (M8 or later) and supergiants (M5 or later). This restriction is made because the yellow supergiants seem to have different polarization properties and these properties most likely extend to supergiants as late as M 2 or even M 4. Also it is not clear if normal red variables can be treated together with infrared objects.
