AFTER the publication of the volume of“Collected Researches” of the National Physical Laboratory at present in the press, that quarto publication will cease and will be replaced by an annual octavo pamphlet entitled "Abstracts of Papers", the first issue of which, for the year 1936, has already appeared. It extends to 65 pages, 61 of which are devoted to 140 abstracts and the rest to author and subject indexes. The title of each abstract is in Clarendon type and that of the publication in which the complete paper is to be found in italics with specification of year, volume and page. The abstracts themselves generally give the object and method of the investigation concerned in outline and the net results in detail, so that a large amount of valuable information is condensed into a small space. They are grouped under subjects. The present issue is published at Is. by H.M. Stationery Office.
