A preliminary Cosmic Diffuse Gamma-Ray spectrum from 0.8 to
30 MeV is presented, using the COMPTEL instrument, the Imaging Compton
Telescope on-board the Compton Gamma Ray Observatory.  The
time-of-flight distribution of the downward-scattered gamma rays and
the pulse-shape measurement of the measured events are used to
estimate the background from the earth and local neutrons.  Additional
neutron-induced background is determined by organizing the data by the
geomagnetic vertical cutoff rigidity. The cosmic diffuse gamma-ray
spectrum at high galactic latitude is derived from the limiting case
of infinite geomagnetic vertical cutoff rigidity.
