RESEARCHES. 



In accordance Avith the original plan of the Institution that its 

 Secretary should devote his time to scientific matters as well as 

 administrative," research work in various fields has been continued 

 under my direction b,y the Institution and its dependencies. 



In the Astrophysical Observatory I have continued work believed 

 to be important, and inaugurated some experiments of novel interest, 

 which are referred to later. 



Through the Museum and the Bureau of American Ethnolog}'^ 

 the Institution has been enabled to carry on various biological, 

 geological, and ethnological researches, which will be found fully 

 described elsewhere in this report. 



HODGKINS FUND. 



P^requent applications for grants from the Ilodgkins fund are 

 received ; and while, as noted in previous reports, the conditions 

 establishing the foundation are such as to measurably restrict the 

 scope of its activities, all requests for aid are carefully considered 

 and acted on. In addition to the researches here mentioned, reports 

 on several interesting investigations, already noted as in progress, 

 are still awaited and will be published later. 



A grant has been approved on behalf of Mr. A. L. Rotcli. of IMiic 

 Hill Meteorological Observatory', whose investigations of the upper 



c Resolved, That the Secretnrj- continue his researches in pliyslcal science, 

 find present such facts and principles as may be developed for publication in 

 the Smithsonian contributions. (Adopted at meeting of the Board of Regents, 

 January 2r,. 1847.)
