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
