CENTRAL COMMITTEES ON RESEARCH 
The National Research Council, with the cooperation of the American As- 
sociation for the Advancement of Science, the American Chemical Society, 
the American Physical Society, the American Mathematical Society, and 
other national scientific societies, has established a series of central committees 
to organize research in the various branches of science. 
The purpose of these committees may be outhned as follows : 
(1) To join in the preparation of the National Census of Research. This 
will be taken by the Census Committee of the Research Council, of which the 
Chairmen of the various central committees are members. 
(2) To prepare reports embodying comprehensive surveys of the larger 
possibilities of research in the various departments of pure science, suggest- 
ing important problems and favorable opportunities for investigation. 
(3) To survey the economic and industrial problems of the United States, 
and report on possible means of aiding in their solution by the promotion of 
research in the fields represented by the various committees. (In coopera- 
tion with the Council's Committee on the Promotion of Industrial Research.) 
(4) To indicate how investigators in each committee's field can aid in the 
solution of research problems involved in strengthening the national defense. 
(In cooperation with the MiHtary Committee of the National Research 
Council.) 
(5) To point out opportunities, national and international, for cooperation 
in research, and to assist in the coordination of the various agencies already 
established for this purpose. 
(6) To keep in touch with the Research Committees of educational insti- 
tutions, and to supply research problems, suggestions, or thesis subjects when 
requested to do so. 
(7) To serve as a national clearing house of information regarding research 
problems in each committee's field which arise from scientific, industrial, 
and other sources, and are communicated to the Council by local Research 
Committees or other agencies. 
(8) To promote research by such other methods as may prove advisable, 
including the encouragement of such courses of instruction in educational 
institutions as are best adapted to develop greater breadth of view, a wider 
understanding of the methods of research, and a more general perception of 
the national importance of all forms of research, both in pure and appHed
