500 PROCEEDINGS OF THE AMERICAN ACADEMY 



graphing, and for a research on a new standard of light. 

 The unexpended balance of the $1000 (viz. $400) will revert 

 to the treasury. 



It was voted to recommend to the Academy the appropria- 

 tion of $500 from the income of the Rumford Fund for the 

 construction and mounting of instruments to be used by 

 Mr. W. H. Pickering in observations upon the solar corona 

 at the time of the total eclipse of the sun, on August 28, 

 1886. The other expenses of the expedition to the West 

 Indies for this purpose will be paid by the members of the 

 party. 



The committee think that the time has come for making 

 another award of the Rumford Premium. They have spent 

 much time in weighing carefully the claims of several can- 

 didates, all of whom are of great merit. After careful con- 

 sideration of the subject, they have voted unanimously to 

 recommend to the Academy that the Rumford Premium be 

 awarded to Prof. S. P. Langley, of Allegheny Observatory, 

 for his researches on radiant energy. To carry out the 

 objects of this report, the committee recommend the adoption, 

 of the votes appended to this report. 



Respectfully for the committee,
