N2  - Observations have been made of galactic radiation at a frequency of 19·7 Mc/s .using an aerial having a beamwidth 1°· 4. The effect of an absobing band of H II regions around the galactic equator is clearly seen. Isolated H II regions, some very faint, have been detected in absorption. A detailed study of the sky near the galactic centre shows that the source Sagittarius-A is observed in absorption at 19·7 Mc/s.
