Observations of the galactic radio emission at 1 �6 MHz have been made during the current solar activity minimum using a radio telescope with a beam width of 25�. The radiation intensity was mapped for six declinations between _12� and _72� and from 1000 to 0500 hours R.A.

New maps of the distribution of the galactic background radio emission are given for wave frequencies of 2�1,3�7,4�7,5�5,8�3,13 and 16�5 MHz. The angular resolutions of the observations were 7.5�, 6.8�, 3 � � 10�, 4.5�, 3.0�, 1.9� and 1.5� respectively. A map of the quantity ?? in galactic coordinates is obtained from an analysis of the changes in the radio brightness distributions with frequency. For an assumed electron kinetic temperature of 104 K, the emission measure is found to vary from 3�9 cm -6 pc near the south galactic pole to 140 cm -6 pc near the equator.

As part of the programme of observations with the large Cambridge radio telescope, a survey of the integrated radio emission has been made using one of the four elements of the interferometer. At a wave-length of 3·7 metres this aerial has beam-widths to half-power points of 2° in right ascension and 15° in declination. The use of a long wave-length makes it possible to obtain accurate measurements of the brightness temperature of the sky in regions away from the galactic plane. It is with the radiation from these regions that this paper is primarily concerned.
