Abstract
We have made measurements of the 1. mm fluxes from the Galactic H n regions DR 21 and the'Orion Nebula. Measurements at 350 have been used in the interpretation of these data. A crude mapping of the Onoji Nebula leads to an optically thin thermal model consisting of a 70 K, 1 arc min source set on a more extended region, 3 arc min in diameter, at a temperature of 30 K. A measured flux density of 32 8 f.u. from DR 21 confirms the excess emission reported at 350 and gives a mean spectral index of -3.1 for the spectral region 350 I.4 mm.
