Abstract
Measurements are described of galactic radiation at frequencies of 1210 and 3000 Mc/s. The results provide extensions of previous radio emission spectra by more than 2� octaves. The intensity of radiation from near the galactic centre was measured and an estimate made of the direction of the maximum of such radiation. A new " discrete source " of peculiar spectrum was discovered very close to the centre of the Galaxy. Evidence suggests that the power output of this and some other sources in the radio spectrum may exceed the total power output of the Sun. Radiation was also observed from the direction of the Crab Nebula, from the known " radio source " in Centaurus, and from the Moon. Two nebulae (M 31 and NGC 7293) were investigated with negative results. The spectra of two sources are given between the limits 18.3 and 1200 Mc/s.
