NEW YORK ACADEMY OF SCIENCES. 



Represented by Dean H. von W. Schulte, M. D., Creighton University, Omaha. 



Mr. President, Ladies and Gentlemen: It is with great pleasure that 

 I am here to bring you the greetings and congratulations of the cele- 

 bration. It is but a short time since the New York academy has ob- 

 served its hundredth anniversary simply and quietly, but with high 

 resolve as benefits these critical years of war, and the good will and best 

 wishes of its members go forth to you with more than ordinary feeling, 

 not merely as to a like-minded body of scientific men, but even more as 

 to an agency in the service of our country in the time of trial. Both 

 societies have given of their membership largely to the national cause; 

 many are in active service, many engaged in special work. It is im- 

 portant that those who cannot from various causes render such direct 

 serv'ice, to remember that upon them also devolve important duties. For 

 we are not alone engaged in suppressing an abominable attack upon 

 culture and civilization; it is also incumbent upon us to demonstrate the 

 superiority of democracy in every field of human endeavor. Those of us 

 who believe that the sciences are at the very root of national prosperity 

 and human progress must prove ourselves no sluggards now. Our uni- 

 versities, our colleges and the community at large, have given the young 

 and strong, the promise of a whole generation, to this great struggle.
