358 PROCEEDINGS OF THE AMERICAN ACADEMY. 



stream of electrons which constitute the cathode rays is produced. 

 A fine tungsten wire is placed at the cathode with exterior terminals 

 so that this can be heated to any desired temperature. It is a 

 well known fact that a wire thus heated liberates electrons so that 

 when these are set free within the tube at the cathode, the electric 

 force has only to direct and propel the freed electrons to the target 

 without having to do the work of producing them. This process 

 allows of the production of an excessively strong cathode stream 

 and also allows the strength and character of the stream to be 

 regulated by varying the temperature of the tungsten wire. 



" The work of Dr. Coolidge has been carried out and brought to 

 success in the Research Laboratory of the General Electric Co. 



"It is pleasing to note that in the awards of the Rumford 

 Premium to Professor Stebbins and to Dr. Coolidge respectively, 

 the Academy has recognized both classes of achievement, for the 

 recognition of which, the Rumford endowment was originally 

 made; for purely scientific work of research in light and heat on 

 the one hand; and on the other, for the advancement of the in- 

 dustrial arts within the borders of these branches of science." 



The Medals were then presented by the President to Dr. 

 Coolidge, who responded, giving an account of his researches.
