A null detection at one of five positions observed in the NGC 2261 reflection nebula was made. Implications of these observations for the mechanism responsible for the linear and circular polarization are discussed. It is concluded that multiple scattering in a flattened distribution is the most likely mechanism in this object and possibly in many other ones. This interpretation means that linear polarization maps provide direct evidence for circumstellar disks around young stellar objects.
