   Polar and Intermediate Polar have been recognized as the subclasses of
   Magnetic Cataclysmic Variables. They are, however, considerably
   different on various aspects, such as mechanical properties and
   emission spectral shape etc., and there is a discussion that these two
   subclasses have completely different origin. From optical observations,
   it is suggested 1H1752+081 is truely an "intermediate" system between
   Polar and Intermediate Polar. We propose 80ksec observation of
   1H1752+081 (1) to measure the rotational period of the white dwarf, (2)
   to detect the soft blackbody component, and (3) to measure the mass of
   the white dwarf.
