Report of the C. M. Warren Committee. 



The C. M. Warren Committee begs to submit the following report: 



The unexpended balance of appropriations held by the Committee 

 at the time of the last report was $1201.50. In March, 1917, a further 

 appropriation of SI 500 was made by the Academy. 



During the past year the sum of $30 has been expended for reprint- 

 ing of certain papers by Professor Charles F. Mabery, copies of which 

 had been exhausted. 



On December 14, 1916, a grant of $250 was made to Professor E, 

 L. Mark to assist in carrying on an investigation of certain properties 

 of sea water at the Bermuda Islands. This carried with it the under-

On January 15, 1917, an additional grant of $150 was made to 

 Professor R. F. Brunei for the purchase of chemicals needed for the 

 continuation of his research on the relation between the constitution 

 of aliphatic radicals and their chemical affinities. 



The amount which remains at the disposal of the Committee at 

 the present time is $2271.50. This sum, of course, is exceptionally 

 large, and under ordinary conditions it would undoubtedly be wise 

 to consider the investment of a part of this sum as an addition to the 

 permanent fund. The Committee is of the opinion, however, that 

 under the present conditions it is better to hold this sum in readiness 

 for its possible use to promote researches which are necessary in con- 

 nection with our national crisis. 



During the past year Professor W. D. Harkins has pu])lished addi- 

 tional papers on Surface Energy in the March and April numbers of 

 the Journal of the American Chemical Society. 



Professor R. F. Brunei has also published results of research work 

 aided by a grant from the Warren Fund on the " Reversible Replace-
