THE twenty-second annual report (E.R.A./T.331) of the British Electrical and Allied Industries Research Association summarizes the work which has been carried out during the year ended September 30, 1942, and, like its predecessor, lists by titles the various research reports which have been issued during the period. The work is reviewed under eighteen major classifications, among which, as was pointed out on the previous occasion, are again the important ones of dielectrics, cables and overhead lines, electric control apparatus, steam-power plant and condensers, magnetic materials, transformers, surge phenomena and rural electrification. The report shows that the work of the Association is now carried on by 112 technical sections, subcommittees and panels comprised of technicians and scientific workers engaged in industry and in universities and other training institutions. Fifty-seven technical reports on a variety of subjects have been issued by the Association during the year, and fifty-one others were in an advanced stage of preparation at the end of the year. These may be divided as follows, giving, in each instance, first new reports and, secondly, reports in preparation: dielectrics, 20, 15; cables and overhead lines, 8, 4 ; electric control apparatus, 15, 16 ; steam-power plant and condensers, 2, 2 ; communication interference, 3, 2; magnetic materials, 2, 2; transformers, 0, 1 ; surge phenomena, 4, 3; safety problems, 0, 3 ; rural electrification, 1, 1 ; transformer noise, 2, 2.
