 dred and fifty dollars to the research fund. In 

 view of his continued financial support of the re-

 in the academy on the strength of his own con- 

 tributions to science. 



The following special resolutions were adopted 

 by the academy:

 that its work, now financially crippled, may be con- 

 tinued with increased support.

 servation of platintum a,nd condemning its use "in 

 jewelry and in any other way that is not productive 

 of scientific or industrial advance or development. ' ' 



3. Urging a like conservation of potassium and 

 the use, wherever practicable, of sodium salts as a 

 substitute for potassium salts in scientific and 

 commercial work. 



4. Endorsing the work of the State Department 

 of Agriculture in establishing preserves for game 

 and other wild life of the state, and appointing a 

 committee to cooperate in this work. This com- 

 mittee, under the chairmanship of Professor Her- 

 bert Osborn, of Ohio State University, is in posi- 

 tion to cooperate also in the nation-wide movement
