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 27th Arthur 

 lecture was delivered in the auditorium of the Natural History Build- 

 ing on the evening of February 2, 1961, by Dr. Herbert Friedman, 

 Superintendent of the Atmosphere and Astrophysics Division of the 

 U.S. Naval Kesearch Laboratory. This lecture will be published in 

 full in the general appendix of the Annual Report of the Board of 

 Regents of the Smithsonian Institution for 1961. 



Dr. Erik Sjoqvist, of the Department of Art and Archaeology of 

 Princeton University, delivered a lecture on "Morgantina, an Un- 

 known Greek City in Sicily" in the auditorium of the Natural History 

 Building on the evening of January 24, 1961. This was sponsored

 America.

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

 bureaus. 



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

 stitution during the year. 



SCIENCE INFORMATION EXCHANGE 



The Science Information Exchange, an agency operated within the 

 Smithsonian Institution, is a clearinghouse for current scientific re- 

 search in process. The basic purpose of the Exchange is to foster 

 and facilitate effective planning and management of scientific research 

 activities supported by United States agencies and institutions by pro- 

 moting the exchange among participating agencies of administrative 

 data about all types of current research. Thus the Exchange provides 

 a means of communication concerning on-going research which pre- 

 cedes publication of research findings, and which prevents unlmowing 

 duplication. 



Abstracts of research-in-process have been for some years regis- 

 tered by investigators engaged in biological, medical, and psycho-
