The GRIS instrument recently made a measurement of the Cosmic Diffuse spectrum during a 32 hour balloon flight from Alice Springs, Australia during 24-26 Oct 1996. A new wide- FOV configuration (100x75deg) of the GRIS instrument with a blocking crystal was used. Upper limits on steps in the spectrum at 847 and 1238 keV due to the integrated contributions of Co-56 from supernovae throughout the universe as predicted by Zdziaski (MNRS, 281, 96) and The et al.(ApJ, 403, 93) will be presented.
