Abstract
Recent observations by the Midcourse Space Experiment (MSX) have revea led the presence of compact objects seen in absorption against bright mid-infrared emission from the Galactic plane. Examination of MSX and IRAS images of these objects reveal that they an dark from 7 to 100 mu m. We find similar to 2000 clouds in a 1 degrees x 180 degrees scan a long the Galactic equator. The data suggest these objects are dense (n > 10(5) cm(-3)), cold (T < 20 K) cores, without accompanying envelope s.
