THE NEW YORK MEETING OF THE AMERICAN 

 ASSOCIATION. 



The annual meeting of the American As- 

 sociation for the Advancement of Science 

 is the chief scientific event of the year, and 

 the meeting about to open in JSTew York 

 promises to be one of the most important 

 in the history of the Association. This is 

 guaranteed by the fact that some fifteen 

 special scientific societies, a considerably 

 larger number than ever before, meet with 

 the Association, and it is definitely proved 

 by the programs issued in advance by most 

 of the sections and by some of the independ- 

 ent societies. These show that the most 

 active men of science from all parts of the 

 country will be present to report upon the 

 results of their most recent researches and 

 to take part in the discussions. It is cer- 

 tainly not only the duty, but also the privi- 

 lege of those interested in science to use all 

 possible efforts to be present at the meeting. 



Those familiar with the history of modern 

 science will realize the difficulties that must 

 be met by an association seeking the ad- 

 vancement and diffusion of science as a 

 whole. The question was comparatively 

 simple when the Association was organized 

 in 1848. Then and until 1875 the mem- 

 bers could meet in one body and in the 

 earlier period at least each could have an 

 intelligent understanding of all the work 

 presented. During this period too there 

 was a general popular interest in science.
