THE BALTIMOEE MEETING 



The Baltimore meeting of the American Association for the Advancement of Science 

 and the aflSliated national scientific societies has never been equalled in size and impor- 

 tance by any gathering of scientific men in this country or indeed elsewhere. It might 

 have been expected that the meetings held in the great centers of population last year and 

 the year before would have set the high water mark of attendance for some years, but the 

 registration at Baltimore was even larger than at New York or Chicago, and the percent- 

 age not registering was greater than ever before. Registration can only be regarded as 

 a habit or duty, as it confers no privilege, the list not even being printed. Of the 300 

 chemists at the New York meeting only 106 registered ; at Baltimore, where the chemists 

 met in a distant part of the city with an attendance of about 400, perhaps not more than 

 50 registered. The actual registration of members of the association was 1088 ; the at- 

 tendance at the meeting can only be guessed, but it may have been in excess of 2,500. 



Size is not in itself significant ; it may be an advantage or it may be a nuisance. But 

 in so far as the growth of the convocation week meetings means an increased number of 

 scientific workers in this country and a willingness on their part to cooperate, it is grati-
