THE BUFFALO MEETING. 



The meeting last week was one of the 

 smallest in the recent history of the Asso- 

 ciation, but it was of unusual interest and 

 importance. The address of the retiring 

 president, which we have already published, 

 was from a master hand, and the meeting 

 was presided over by one of the great men 

 of science of the world. The scientific work 

 of the sections was as a rule good, and in 

 several cases, especially in chemistry, in 

 geology and in botany, was excellent. We 

 must count on another comparatively small 

 meeting at Detroit next year, but we be- 

 lieve that the outlook has never during the 

 present decade been more hopeful for the 

 Association. 



The American Association for the Ad- 

 vancement of Science has two serious diffi- 

 culties with which it must contend. One 

 of these is the scattering of American men 

 of science over a wide territory; the other 

 is the increased specialization in science
