  We present the results of OSSE observations of the soft gamma ray continuum
emission from the Galactic plane at longitude 95 degrees. Emission is detected
between 50 and 600 keV where the spectrum is fit well by a power law with
photon index -2.6+-0.3 and flux (4.0+-0.5) 10^{-2} photons/s/cm^2/rad/MeV at
100 keV. This spectral shape in this range is similar to that found for the
continuum emission from the inner Galaxy but the amplitude is lower by a factor
of four. This emission is either due to unresolved and previously unknown point
sources or it is of diffuse origin, or a combination of the two. Simultaneous
observations with OSSE and smaller field of view instruments operating in the
soft gamma ray energy band, such as XTE or SAX, would help resolve this issue.
If it is primarily diffuse emission due to nonthermal electron bremsstrahlung,
as is the >1 MeV Galactic ridge continuum, then the power in low energy cosmic
ray electrons exceeds that of the nuclear component of the cosmic rays by an
order of magnitude. This would have profound implications for the origin of
cosmic rays and the energetics of the interstellar medium. Alternatively, if
the emission is diffuse and thermal, then there must be a component of the
interstellar medium at temperatures near 10^9 K.
