DOCTORATES CONFERRED IN THE BY AMERICAN UNIVERSITIES 1931-1932 SCIENCES COMPILED FOR THE RESEARCH INFORMATION SERVICE NATIONAL RESEARCH COUNCIL BY CALLIE HULL AND CLAREN CE I. WEST This is the thirteenth year in which the Research Information Service has compiled the information concerning doctorates conferred in the sciences by American universities. Statistics before ~g~g-~g~o are avail- able from reports of other compilers. It is interesting to see the steady increase in the number of doctorates each year from 330 in ~9~9-~920 to ~24~ in ~93~-~932. In the first list compiled by the Research Information Service thirty-one universities reported. In the present list there are sixty-five universities. In many cases the information for previous years was not given, so that the statistics for some of the universities are incomplete. During the period covered by this compilation, the same subject clas- sification has been used, in order that the statistics might have some comparative value, even though this means that many of the more recently recognized subdivisions of the major fields of science are not given a separate place in the classification. It has been deemed necessary, however, to add Public Health (in ~926), Medicine and Surgery (in ~930) and Seismology (in ~932), as scattering the theses on these sub- jects throughout the compilation gave no indication of the work in these fields. It should be pointed out that in the classification of the following doc- torates, the compilers have had only the title of the thesis and, in most cases, the department in which the doctorate was granted. This has often nude it difficult properly to place certain theses and may account for the fact that a thesis appears under one subject, when in reality it belongs under quite a different subject. The Research Information Service wishes again to express its ap- preciation of the cooperation of the Registrars and the Deans of the universities in making possible this compilation. ~ Since ~926 the compilations have appeared in the Reprint and Cir- cular Series of the National Research Council (Numbers 75, 80, 86, 9~, 9: and bosh. Before that time they were published in Science and in School and Society.
