The main program of the Sydney 19.7-Mc/s cross is devoted to the observation of the brightness distribution in a strip, extending some 10 degrees on either side of the galactic equator, the particular interest being the detection of absorption in HII regions. This program is well advanced, but since observing time is limited by ionospheric absorption and interference, records are not yet available for a number of galactic crossings. The detailed analysis of the observations has just begun, and will take some time. In the meantime a rough analysis of the data has been made in order to get a general picture of what might be expected, and this paper gives an outline of the results. The application of various instrumental corrections and the detailed analysis of ionospheric effects may subsequently necessitate some changes in the numbers involved in the calculations, but it is expected that the general conclusions will still hold.
