288 JOURNAL, OF THE WASHINGTON ACADEMY OF SCIENCES VOL. U, NO. 12 



The semi-annual meeting of the Advisory Committee on Non-Ferrous 

 Alloys was held at the Bureau of Standards on April 20 and was attended by 

 members of the various technical societies representing the non-ferrous 

 industries and also by representatives from the technical services of the War 

 and Na\T Departnients. The subjects discussed included specifications 

 for hard-drawn brass wire for airplane bomb release, rotating bands for pro- 

 jectiles, various aircraft problems related to aluminum alloys, questions 

 concerning the composition of bearing metals, corrosion and etching of metals, 

 and the part played by gases in metals. 



The new Low Temperature Laboratory of the Bureau of Mines was dedi- 

 cated by Madame CuRiE at 10 a.m. on Saturday, May 21. 



The National Screw Thread Commission met at the Bureau of Standards 

 on Monday, April 18, and considered the Progress Report recently issued 

 and outlined a program for continuing the work of the Commission. 



Messrs. L. H. Adams and E. D. Williamson of the Geophysical Laboratory, 

 Carnegie Institution of Washington, have received the Longstreth Medal 

 from the Franklin Institute of Philadelphia in recognition of their work on the 

 annealing of glass. 



Dr. C. F. Brooks, meteorologist at the Weather Bureau and editor of the 

 Monthly Weather Review, has resigned, effective June 30, to accept the asso- 

 ciate professorship of meteorology and climatology at Clark University, 

 Worcester, Massachusetts. 



Mr. F. C. Brown of the Bureau of Standards returned in May from a two 

 months' trip to the scientific institutions of England, France, and Germany. 



A meeting in honor of Madame CuRiE was held at the National Museum 

 on Friday evening. May 20. Dr. Robert A. Millikan of the University 

 of Chicago lectured on Radium. 



Dr. Frederick B. Power, of the Bureau of Chemistry, was presented with 

 a gold medal by Mr. Henry S. Wellcome, founder of the Wellcome Chemical 

 Research Laboratories of London, "in commemoration of his eighteen and 

 one-half years of service as Director of the Laboratories and in recognition of 

 his many valuable researches in the field of organic chemistry." The pre- 

 sentation took place at the Cosmos Club on May 9. 



Dr. Edward Bennett Rosa, chief physicist of the Bureau of Standards, 

 died suddenly in his office at the Bureau on May 17, 1921, in his sixtieth year. 

 Dr. Rosa was born at Rogersville, New York, October 4, 1861. After gradu- 

 ation at Wesleyan and Johns Hopkins Universities, he became instructor 

 at the University of Wisconsin, and then professor of physics at Wesleyan. 

 He was appointed chief physicist of the Bureau in 1901. At Wesleyan he 

 developed the physical side of the respiration calorimeter with W. O. AtwaTER. 

 At the Bureau his attention was directed to the determination of the funda- 

 mental electrical units and constants, including the ampere and the electro- 

 magnetic-electrostatic ratio, and also to numerous engineering problems, 

 particularly during the War. During the past three years he had devoted 

 much thought and labor to the problem of the Federal Government's scien- 

 tific personnel and its reclassification by Congress, and his papers on this 

 subject, first published in this Journal^ and widely reprinted, have focussed 

 much public attention upon this important matter. He was a member of the 

 Academy and the Philosophical Society of Washington, as well as of many 

 national scientific and technical organizations.
