Abstract
In Paper I spectra were obtained for the radio emission from the galactic halo and for the broad galactic disk in the direction of the anti-centre. The spectral index was found to vary markedly with frequency. On the assumption that the radiation is due to the synchrotron mechanism, these results may be used to investigate the energy distribution of the electrons and to compare the magnetic field strengths in the two regions of the Galaxy. It appears that there is a sharp change in the energy distribution at an energy of about a few BeV and that the magnetic fields responsible for the emission from the two regions are of comparable strength.
