 properties of sodium vapor. 



Oct. 12, 1904. One hundred dollars ($100) to Professor N. A. Kent as 

 an addition to a former appropriation in aid of his research on the critical 

 conditions influencing electric spark lines. 



Oct. 12, 1904. One hundred and fifty dollars ($150) to Professor 

 A. L. Clark as an addition to a former appropriation in aid of his research 

 on the molecular properties of vapors in the neighborhood of the critical 

 point. 



Jan. 11, 1905. Two hundred dollars ($200) to Professor D. B. Brace 

 as an addition of a former appropriation in aid of his research on electric 

 double refraction in gases. 



Feb. 8, 1905. One hundred and fifty dollars ($150) to Professor

At the same meeting it was voted to request the Academy to appropri- 

 ate from the income of the Rumford Fund the sum of two hundred 

 dollars (S200) to Professor E. H. Hall of Harvard University in aid 

 of his research on the thermal and thermo-electric properties of iron and 

 other substances. 



In considering possible ways of increasing the usefulness of the Rum- 

 ford Fund the Committee came to believe that it was desirable to publisli 

 a pamphlet regarding its character and the scientific results attained by 

 its aid which could be distributed among scientific men. At the request 

 of the Committee, the Academy has made an appropriation for the purpose 

 from the income of the Fun<l, and the publication is now in press. 



At the meeting of April 12, 1905, the Committee voted : —
