THE AMERICAN ASSOCIATION FOR THE 

 ADVANCEMENT OF SCIENCE. 



The fifty-second annual meeting of the association, which was held in Washington, 

 D. C. , from December 29 to January 3, was noteworthy in many respects as marking the 

 passage to a new order of things in the position and conduct of the association. The 

 total enrollment reached 989, which is second to that of the Boston meeting in 1880, when 

 997 were enrolled, and to that of the second Philadelphia meeting in 1884, when 1,261 

 enrollments appear. Of these, however, 303 members of the British Association represent 

 complimentary enrollments. The geographic distribution of the members in attendance 

 was as follows : 



District of Columbia, 354; New York, 133; Massachusetts, 82; Pennsylvania, 70; 

 Ohio, 39; Maryland, 38; Illinois, 27; Connecticut, 23; Michigan, 22; New Jersey, 

 19; Wisconsin, 19; Indiana, 16; Virginia, 14; North Carolina, 13; California, 12;
