THE FIFTIETH ANNIVEBSABY OF THE 

 AMERICAN ASSOCIATION. 



The American Association for the Ad- 

 vancement of Science celebrated the fiftieth 

 anniversary of its foundation at Boston from 

 the 20th to the 27th of August. The meet- 

 ing, as all knew would be the case, was 

 eminently successful, both in regard to the 

 scientific work accomplished and in the oc- 

 casions for social intercourse and enjoyment 

 so liberally provided. As stated in the re- 

 port of the new Permanent Secretary, Dr. 

 L. O. Howard, at the closing session, the 

 meeting was in many respects the most 

 successful in the history of the organiza- 

 tion. In point of numbers the attendance 

 made it the fourth meeting in the history 

 of the Association. Two of the meetings 

 which have exceeded it in attendance have 

 been held in conjunction with the British 

 Association for the Advancement of Science, 

 and the third was held in Boston ; so that 

 Boston has been excelled only by Boston. 

 The scientific and other advantages of 

 Boston, and the fact that the meeting cele- 

 brated the fiftieth anniversary of the found- 

 ing of the Association, attracted members 

 in large numbers. The total registration 

 was 903, and almost every State in the 

 Union was represented. The State which 

 had the largest representation was natur- 

 ally Massachusetts, with a total of 231 ; 

 ISew York came second, wdth 158, and 

 the District of Columbia third, with 96.
