dollars to Mr. Arthur L. Clark of the Worcester Academy in further- 

 ance of a research on the Molecular Properties of Vapors in the Neigh- 

 borhood of the Critical Point. This recommendation has still to be 

 acted upon. 



The attention of the Committee had several times been called to the 

 fact that for a long period of years there had been no way, except by a 

 formal vote of the Academy, in which a person other than a member 

 could purchase a copy of the Life and Works of Count Rumford. Mean-

 of the Rumford Premium. Among the various candidates whose claims 

 were discussed, there was one who without dissent was considered in 

 the highest degree worthy of the honor. The numerous researches of 

 Professor Carl Barus in various branches of heat, carried on for many 

 years, have uniformly been characterized by great skill, accuracy, and 

 originality, and these valuable contributions to science are generally 

 recognized as of far-reaching importance. 



It was unanimously voted by the Committee, for the first time on 

 January 10, and for the second time on April 9, 1900, to recommend lo
