The committee on the State Biological Survey 

 reported that a definite organization had finally 

 been accomplished through the cooperation of 

 twelve educational institutions of the state and 

 that a limited fund would at once be available 

 toward beginning the work. The survey will be in 

 charge of the director. Professor Herbert Osborn, 

 of Ohio State University, and an administrative 

 board consisting of a representative from each 

 cooperating institution. The report was accepted 

 and the committee dismissed. 



The society adopted resolutions expressing its 

 sense of loss in the death of three members during 

 the year. Dr. Joshua Lindahl, Dr. P. A. Hobbs 

 and Dr. H. L. True. Dr. Lindahl served the 

 society as its president in 1900, and during his 

 residence in Ohio had always taken an active 

 interest in the success of the academy. 



A resolution requesting legislation along the 

 following lines was aJso adopted: 



Sesolved, that it is the sense of this academy 

 that the legislature of Ohio should pass a law 

 designed to make it impossible for the insane, the 

 feeble-minded and the confirmed criminals to 

 propagate their kind. That to this end we com- 

 mend to its attention and study the laws providing 

 for sterilization already in force in six of the 

 United States. That copies of this resolution be 

 sent to the several county and city medical socie- 

 ties of Ohio, asking their cooperation in the ac- 

 complishment of this purpose. 



After adopting additional resolutions expressing 

 the appreciation of the society for the courtesies 

 extended by the faculty and others connected with 

 the university, and furthermore thanking Mr. 

 Emerson McMillan, of New York, for his con- 

 tinued donations to the research funds of the 

 society, the academy adjourned to meet at Oberlin 

 next November. 



A department of physics was organized and 

 21 new members added, making the total member- 

 ship 214.
