220 CARNEGIE INSTITUTION OF WASHINGTON. 



Dr. Arthur A. Noyes, Director of the Research Laboratory of Physical 

 Chemistry and for two years Acting President of the Massachusetts 

 Institute of Technology, was appointed Director of Chemical Research. 

 For several years Dr. Noyes spent three months annually in Pasadena, 

 but in 1919 he resigned from the Massachusetts Institute and removed 

 permanently to California. In that year a further gift of $200,000 

 was received as an endowment fund to initiate research in physics, 

 and Dr. Robert A. Millikan, Professor of Physics in the University of 

 Chicago, was engaged as Director of Physical Research, spending three 

 months of each year in Pasadena. During the past year several gifts 

 to the Institute, includmg large additions to the endowTnent fund and 

 $500,000 from Dr. Norman Bridge for a physical laboratory and 

 library, have permitted the trustees to carry out their original plans. 

 Dr. Millikan lias accepted permanent appointment as Director of the 

 Norman Bridge Physical Laboratory and, beginning this autumn, will 

 spend all of his time in Pasadena. As his chief object is to continue 

 his investigations on a larger scale and to build up an important cen- 

 ter of research, he prefers not to accept the position of president, 

 left vacant in 1920 by the resignation of Dr. Scherer because of ill 

 health. He will, however, be Chairman of the Executive Council, 

 which will have charge of the administration of the Institute. This 

 will consist of three members of the Board of Trustees, Mr. Arthur H. 

 Fleming, Mr. Henry M. Robinson, and the writer, and three members 

 of the faculty, Messrs. Millikan, Noyes, and Barrett (secretary of 

 the Institute). 



These details are given because of the close relationship which will 

 hereafter exist between the Mount Wilson Observatory and the Cali- 

 fornia Institute of Technology. As during the past year, the members 

 of the Observatory staff will meet weekly with the investigators of 

 the Bridge and Gates Laboratories to hear reports on current research 

 and discuss problems of common interest. They will also be invited 

 to attend the courses of lectures to be given at the Institute by eminent 

 men of science, who will include for the coming year Professor H. A. 

 Lorentz of Haarlem, and Professor Paul Epstein, formerly of Leiden and 

 now a member of the faculty of the Institute. Furthermore, a joint 

 study of the constitution of matter and the nature of radiation will be 

 organized, in which the astronomical, physical, and chemical aspects 

 of these problems will be attacked by the members of the three groups 

 immediately concerned. 



In assembling the powerful instrumental equipment required for this 

 work, the three laboratories will act in close cooperation. Thus the 

 provision, by the Southern California Edison Company, of a high- 

 tension laboratory on the campus of the Institute, to contain a 

 1,000-kw. transformer, giving approximately 1,000,000 volts, will ren- 

 der the acquisition of similar apparatus by the Observatory unneces-
