RESEARCH IN GEOPHYSICS

    Abstract

    THE annual report of the director of the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, published in December 1940, is an important record of achievement carried out under difficulties caused by war. It describes the initiation of several fresh experimental projects, the continuance of the previous programme of field observations, the reduction of existing data, the organization of and participation in several important congresses, and the publication of a large number of scientific papers.
