A FEW years ago the Australian Council for Scientific and Industrial Research established a Radio Research Board to conduct scientific and technical research into some of the more fundamental problems associated with radio communication. Amongst the items of work which it was planned to carry out were the repetition of some of the investigations already in progress in Great Britain under the British Radio Research Board, with the view of obtaining a direct comparison of the propagation of electric waves in the two hemispheres. As a useful aid in this matter some of the investigators appointed in Australia had the advantage of receiving their training in radio research under the organisation in Great Britain. The results of the work already carried out in Australia are being published in a series of special reports, and the latest of these is entitled “Atmospherics in Australia (I)”.* This report contains the results of observations made chiefly by means of two cathode ray oscillograph direction-finders supplied by the British Radio Research Station at Slough, where this type of instrument has been developed to a high degree.
