TEE RELATION OF THE ACADEMY TO THE 



STATE AND TO THE PEOPLE OF 



THE STATEi 



We are celebrating the twenty-fifth anni- 

 versary of an institution whose existence is 

 unknown to the great majority of the peo- 

 ple of Ohio. Yet it has enjoyed a prosper- 

 ous life of a quarter of a century during 

 which it has held many meetings in differ- 

 ent parts of the state. At these meetings 

 important results of original research on 

 the part of its members were presented, 

 many of which have been published by the 

 academy and in various scientific journals, 

 thus becoming a part of the great store of 

 learning which the world is accumulating. 



The academy can not be fairly charged 

 with undue exaltation of its own merit or 

 importance in the past and, as an incor- 

 porated institution of the state it has a 

 right to think that some consideration 

 should now be given to the relations which 

 it might and should sustain to that state 

 and to the people of the state. 



As a preface to such consideration it 

 seems desirable to refer to the views of a 

 few persons who would naturally be among 

 its most active supporters did they not be- 

 lieve that under present conditions there is 

 no good reason for the existence of such a 

 society as the Ohio Academy of Science, con- 

 tending that other organizations of a similar 

 character, mostly national in their scope, 

 offer as good or better facilities for the ac- 

 complishment of the principal ends the acad- 

 emy has in view. There is enough ground 

 for such a contention to justify a reply. 



Of the many remarkable social evolutions
