THE recent report of the Committee of Seismological Investigations records much useful work done by its members. During the preceding year, three slight earthquakes occurred in the British Isles: in East Kent on December 29, 1936, in North Staffordshire on April 7, 1937, and near Inverness on June 26, 1937. Brief references are made to the study of the recent earthquakes in Montserrat, to Mr. Brennan's work on the greater frequency of earthquakes in Jamaica during the dry months of the year, to the deep-focus earthquakes of 1932, and to the new globe, 18 in. in diameter, recently installed at Oxford, which has already proved most useful in the determination of epicentres. Notes are also contributed by Dr. H. Jeffreys on seismic transmission times, and by Dr. R. Stoneley on his study of the records of the Mongolian earthquake of August 10, 1931.
