ADDRESS BY THE PRESIDENT, PROFESSOR 



HENRY E. OSBORN, AT THE FIFTH 



ANNUAL RECEPTION. 



Members of the Academy and of the Scientific 

 Alliance : Welcome to the Fifth Annual Recep- 

 tion ! 



An Academy of Science stands as a 

 clearing house for scientific ideas ; for the 

 encouragement, diffusion and interchange 

 of methods and principles between all 

 branches. The elasticity of our own Acad- 

 emy is well illustrated in this fifth an- 

 nual exhibition of the progress of science. 

 Thanks to the energy of our Secretary, 

 Professor Dodge ; of the Chairmen of the 

 many different sections and the cooperation 

 of institutions in all parts of the country, 

 it appears to cover a broader field than ever 

 before. Here you can obtain glimpses of 

 the work in many lines progressing at Har- 

 vard, the Johns Hopkins, Princeton, the 

 U. S. Coast Survey, Chicago, the Troy Poly- 

 technic, the Allegheny Observatory, besides 

 our own City College, University of IS'ew 

 York, Columbia University and, not least, 

 this great Museum. 



Methods. — Here, too, the methods and in- 

 struments of research, as well as the re- 

 sults of work in the most diverse fields of 

 scientific enterprise, are brought together 

 and stimulate us by their very contrast. 

 Our inventiveness is as notable in the beau- 

 tifully delicate instruments for studying
