NEITHER science nor industry is standing still and to anyone who wishes to keep abreast of the advances made, the two sections of Science Abstracts—Physics and Electrical Engineering—are of great service. The two index numbers published in the last week of February completed the volumes for 1938. The Physics Section contains 5,081 abstracts from about half that number of publications, the average number of the abstracts being about 4.3 per page. The index of subjects covers 189 pages, that of apparatus 22, and the author index 65 pages. The Electrical Engineering Section has 3,622 abstracts, about 4.6 to a page, with a subject index of 59 pages and an author index of 31 pages. The Physics volume is thus about 10 per cent less than, and the Electrical Engineering volume about 3 per cent larger than, the volume for 1937.
