Abstract

(1) THE ” International Seismological Sum-A mary” is a comprehensive work in which practically every reading of every seismo-gram at every Seismological station in the world is placed on record and co-ordinated. The ” Summary” is prepared at the University Observatory, Oxford. Since the death of Prof. H. H. Turner, who inaugurated the work, the tabulations have been prepared and edited by Mr. J. S. Hughes and Miss E. F. Bellamy. To the cost of production contributions are made by the International Seismological Association (one of the constituent bodies of the International Union for Geodesy and Geophysics), the British Association and the University of Oxford. The provision of funds for this enterprise has always presented difficulties, which are really due to the inadequate share of its income allotted by the International Union to the Seismological Association. There was much discussion of this matter during the Lisbon meeting of the Union, until M. Rothé, the secretary of the Association, generously moved a resolution by which the reserve funds then in hand were allotted to the “Summary”. Special grants have also been given by the British Association to tide over the period up to the Edinburgh meeting of the Union. From the first issue, that for 1918, the “Summary” has appeared in quarterly parts. This plan, though acceptable to active investigators who have had the results of the co-ordinating work at Oxford in their hands as early as possible, has obvious disadvantages, and the “Summary” for 1930 was offered to regular recipients alternatively in parts or as a bound volume. Nearly half preferred the latter form. Their patience is rewarded by the possession of a neat volume, appropriately bound in Oxford blue.
