 at the University of Paris. His course of lec- 

 tures will be on the general subject of " Phys-

 terference methods." 



The Rumford Committee of the American 

 Academy of Arts and Sciences has recently 

 jnade the following appropriations: To Pro- 

 fessor P. W. Bridgman, of Harvard Univer- 

 sity, $400 in aid of his research on the thermal 

 .and optical properties of bodies under high 

 pressure; to Professor Paul F. Gaehr, of "Wells 

 College, $250 in aid of his research on the spe- 

 cific heat of tungsten. 



The Carnegie Institution of "Washington 

 has appropriated $750 for the support of the 

 work of Dr. S. J. Holmes, professor of zool- 

 ogy in the University of California, on the 

 factors of evolution in man. 



Mr. Edwin Kirk, who resigned from the U. 

 S. Geological Survey in April, 1920, to do 

 private work in South America, has been rein- 

 stated as geologist with the Survey.

 em slopes of the Andes in search of plant 

 rusts. They went southward about as far as 

 the island of Chiloe and northward to Quito, 



a range of forty degrees of latitude. Over a 

 thousand numbers were secured, in most part 

 supplemented by phanerogamic specimens of 

 the hosts. The collection is notable for its 

 large proportion of grass rusts. 



Dr. F. Gowland Hopkins, professor of bio- 

 chemistry at the University of Cambridge, will

The following Mayo Foundation lectures
