LECTURES 



In 1931 the Institution received a bequest from James Arthur, of 

 New York City, a part of the income from which was to be used to 

 endow an annual lecture on some aspect of the sun. The 26th Arthur 

 lecture was delivered in the auditorium of the Natural History 

 Building on the evening of October 15, 1959, by Dr. Alan Maxwell, 

 research associate of the Eadio Astronomy Station of Plarvard Col- 

 lege Observatory, Fort Davis, Tex., on the subject "Radio Waves from 

 the Sun." This lecture, the first in the series that has been concerned 

 with radio astronomy, was published in full in the general appendix 

 of the Annual Report of the Board of Regents of the Smithsonian 

 Institution for 1959. 



Dr. George E. Mylonas, professor and chairman of the Department 

 of Art and Archaeology of Washington University, St. Louis, Mo., 

 delivered a lecture on "Eleusis, Its Sanctuary and Cemetery" in the 

 auditoiium of the Natural Histoiy Building on the evening of Febru- 

 ary 25, 1960. This was sponsored jointly by the Smithsonian and the 

 Archaeological Institute of America. 



Several lectures were also sponsored by the Freer Gallery of Art 

 and the National Gallery of Art. These are listed in the reports of 

 these bureaus. 



Many other lectures on technical subjects were given at the Smith- 

 sonian during the year. 



BIO-SCIENCES INFORMATION EXCHANGE 



The Bio-Sciences Information Exchange, an agency operated within 

 the Smithsonian Institution but financed by other Government agen- 

 cies, is a clearing house for research in the life sciences. 



Abstracts of on-going research are registered by investigators en- 

 gaged in biological, medical, and psychological research and in limited 

 aspects of research in thQ social sciences. Through an extensive sys- 

 tem of subject indexing, these abstracts are provided upon request 

 and without charge to researchers in research institutions. Tlirough 

 this simple mechanism, the Exchange maintains a commmiication 

 system which precedes publication and prevents unknowing duplica- 

 tion. For granting agencies and properly constituted committees it 

 prepares extensive sui'veys of research in broad areas.
