The J 1 to 0 emission of CO has been surveyed in the galactic plane between l -10 and 90 degrees with a 1 beam sampling every degree. Molecular clouds emitting in the CO line are plentiful over the inner region of the galaxy. Their greatest number occurs in the galactic nucleus and at a radius of 5.5 kpc - a distribution similar to radio H II regions but very different from that previously derived for atomic hydrogen. The total mass in molecular clouds is found, and each typically has an average density of 500cc, and a temperature of 7 K. These results suggest that most of the interstellar medium in the interior of the galaxy is molecular H2.
