HEADQUARTERS OF THE ACADEMY AND RESEARCH COUNCIL

The National Academy of Sciences and the National Research Council occupy jointly a beautiful and commodious marble building in Washington, which, with its grounds, covers the block between B and C Streets and Twenty-first and Twenty-second Streets, with a frontage on B Street facing the Mall near the Lincoln Memorial. This building, which is one of the most beautiful among the larger structures of Washington, was made possible by funds provided by the Carnegie Corporation of New York on a site made available by gifts from a score of private individuals desirous of enabling the academy and council to have suitable headquarters in the National Capital.

The architect of the building was the late Bertram Grosvenor Goodhue. The general architectural scheme, which was approved by the Fine Arts Commission for public buildings in Washington, is classical, but does not include the use of external detached or engaged columns.

The building contains a number of important exhibits which may be classified in two groups-first, a group of permanent exhibits installed to show such phenomena as the rotation of the earth, the image of the sun showing the changing sun spots, the variations in the earth's magnetic field, records of earthquakes, etc. The others, which are occasionally changed, are planned to show recent important scientific discoveries and appliances in any or all of the special fields of the physical and biological sciences, and thus serve as a sort of current record of scientific advance.

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES

The National Research Council has continued to share in the editorial and financial responsibility of the Proceedings of the National Academy of Sciences. It has contributed during the year $2,500 to assist in meeting the expenses of the Proceedings and has been represented on the managing and editorial boards by the following members of the research council: Member of the editorial executive committee, Vernon Kellogg; members of the editorial board, Messrs. George K. Burgess, Knight Dunlap, George A. Hulett, Arthur Keith, Vernon Kellogg, Dayton C. Miller, Elmer A. Sperry, William Charles White, and Lorande L. Woodruff.

PUBLICATIONS OF THE NATIONAL RESEARCH COUNCIL

The National Research Council has published six numbers in its bulletin series (major and technical papers usually of considerable length) during the year, and seven numbers in its reprint and circular series (shorter and usually more general papers), in addition to reprinting Bulletin No. 51 (1925), Radioactivity, by A. F. Kavarik and L. W. McKeehan. The total number of publications in the bulletin series is now 69, and in the reprint and circular series the number is 88. Several additional papers are now in press. Various miscellaneous publications have also been issued. (For list of titles of all publications of the research council issued prior to January 1, 1928, see No. 73 of the reprint and circular series.) More recent titles are given in the annual reports of the various divisions of the council. The publications issued in the two series during the year July 1, 1928 to June 30, 1929 are as follows:

FINANCIAL STATEMENT

From July 1, 1928, to June 30, 1929, the receipts from the sale of separate publications have been $4,320.79. This amount includes receipts from subscriptions to both series.

The National Research Council, with the financial assistance of the Rockefeller Foundation, maintains three series of research fellowships for men and women who have comparatively recently received their doctor's degrees or who have equivalent qualifications and have proved their capacity for scientific investigation. The series so far

established are in the physical, chemical, and mathematical sciences; the medical sciences; and the biological sciences, including zoology, botany, anthropology, psychology, agriculture, and forestry. These fellowships are granted only for the purpose of carrying on research work in well-equipped university or other laboratories under the general direction of competent specialists with a view to the development of the research capacity of the fellows. The appointments and administrative oversight of each group of fellows are in charge of a special board of outstanding American scientific men. The stipends attached to the fellowships are intended to enable the holders to give all their time and attention to their research work.

The total sum that has so far been made available to the council to maintain these fellowships is $3,026,025. This money has been provided not as endowment but as capital to be expended over limited periods. For the series in physics, chemistry, and mathematics $1,155,000 has been provided over a period of 11 years (1919-1930), including a special sum for American fellows working abroad; for the series in the medical sciences, $500,000 for one 5-year period, an additional $100,000 for a 1-year period, and an additional $250,000 for a second 5-year period (1922-1932, inclusive); for the series in the biological sciences, $325,000 for an initial 5-year period, $75,000 for an interim period of one year, $500,000 for a second 5-year period (1923-1934), and in addition about $46,025 in special funds for American fellows working abroad, and $75,000 made available during the past year for the special support over a 3-year period (1929-1932) of fellowships in agriculture and forestry.

On October 1, 1928, there were a total of 124 fellows under appointment from these three boards, 67 in physics, chemistry, and mathematics; 20 in the medical sciences; and 37 in the biological sciences. The past fellows of these boards on the same date numbered 359. The members of the special boards in charge of these fellowships, together with the names of the fellows active during the current year, are given later in this report (see Appendix 5).

By a reciprocal arrangement with the Rockefeller Foundation the fellowship boards of the National Research Council undertake the supervision of the work of European fellows appointed by the Rockefeller Foundation to work in the United States, while the foundation, through its offices in Paris, supervises the work of American fellows appointed by boards of the research council to work abroad.

In addition to these general series of research fellowships the council has received funds in smaller amounts from several sources for the maintenance of research fellowships in certain specified biological fields. These are referred to later in this report.

GENERAL ACTIVITIES OF THE EXECUTIVE BOARD

Chicago centennial celebration.-As a consequence of preliminary inquiries from the trustees of the Chicago World's Fair Centennial Celebration, a request was received during the summer of 1928 to assist the trustees in planning the scientific aspects of the international exposition which it is proposed to hold in 1933 to commemorate the past "Century of Progress" since the incorporation of the city of Chicago in 1833. At the meeting of the executive board, October 9, 1928, the board voted to indorse in principle the proposal of the trustees "to develop an exposition which shall be largely devoted to showing the progress of science and its application to the industries in the past hundred years, and to make manifest to the public the present rôle of science in our national life," and authorized the appointment of a preliminary committee to confer further with the trustees of the centennial celebration in regard to the nature and extent of the assistance desired. This committee presented a recommendation at the meeting of the executive board, February 12, 1929, to the effect that the council lend its assistance to this undertaking in an advisory capacity by appointing a representative committee of "eminent and influential men in the several fields of pure and applied science to act on behalf of the council as an advisory committee to the Centennial Celebration Association" in formulating a "general plan for the exposition which can be carried out with reasonable uniformity as regards the various fields of science." This recommendation was adopted and during the spring the advisory committee was appointed. The committee is now organized in three groups, an executive committee of the seven members who constituted the preliminary committee, a group of about 35 professional and technical members appointed with the advice of the presidents of national societies of science and technology, and a group of 15 members at large.

This science advisory committee held its first meeting in New York City on June 21, and arranged for the organization of subcommittees in the several fields of science represented with a view to obtaining the suggestions of these subcommittees as to a general scheme for presenting the contributions of science to human welfare in their respective fields, with the intention of constructing from the consolidated suggestions of these subcommittees a comprehensive plan for the portrayal of the scientific progress of the past century to be applied by the trustees in preparing the exposition.

Cooperation with the Bureau of Standards. By special arrangement with the Bureau of Standards the council undertakes the administration of certain funds contributed by industrial concerns and individuals for the support of research work in which the bureau is cooperating with the industries. Up to the close of the present year 15 such
