  A definition of depolarization factors for anisotropic ellipsoid in an
anisotropic medium is considered. The expressions for these factors are
derived, which generalize some results known for special cases, and differences
from the usual depolarization factors for ellipsoid in isotropic medium are
described. The concept of "reduced" ellipsoid, allowing visually describe the
effect of the medium anisotropy on depolarization is also introduced.
