Abstract
THE thirty-ninth report of this Committee is chiefly concerned with the maintenance of the International Seismological Summary. The University of Oxford has agreed to provide room and part of the working expenses until the time comes when these can be met entirely from sources outside the University, such as the International Union for Geodesy and Geophysics, the Crombie and Gray-Milne funds, and the British Association grants. The summary for the third quarter of 1930 is now in course of preparation, and in this the Committee is able to avail itself of the new Jeffreys-Bullen tables, the accuracy of which will greatly help in the determination of epicentres. The precision of the work now being carried on is evident from the suggestion that the time is approaching when the spheroidal form of the earth will have to be taken into account in the estimation of distances.
