THE CHICAGO MEETING 



The seventy-third meeting of tlie Americam 

 Association for the Advancement of Science, 

 held in Chicago from December 27 to Jan- 

 nary 1, was the second of the greater convoca- 

 tion week meetings of the association and of 

 the national scientific societies associated with 

 it, convened once in four years successively in 

 New York, Chicago and Washington. The 

 remarkable scientific activity of the central 

 west and of the reconstruction period follow- 

 ing the war were adequately reflected by the 

 attendance and programs at Chicago, which 

 have probably not been surpassed by any 

 previous gathering of scientific men in this 

 or any other country. In addition to four- 

 teen sections of the association, forty-one 

 national scientific societies met in Chicago 

 and the official program of 112 pages ex- 

 hibited the scientific productivity of the na- 

 tion in the whole range of the natural and 

 exact sciences. 



The association has been fortunate in its 

 presidents. The address of the retiring pres- 

 ident, Dr. Simon Flexner, director of the 

 laboratories of the Rockefeller Institute for 

 Medical Research, on " Twenty- five years of 

 bacteriology," printed in the last issue of 

 Science, was an admirably clear presentation 

 of a subject unsurpassed in its importance 

 to human welfare, described by one y^o has 

 led in the work. Dr. L. O. Howard, chief 

 of the Bureau of Entomology, presided with 

 dignity, skill and tact. He has played a 

 large part in a subject in which science has 

 demonstrated its service in the economic 

 development of the nation and has been the 

 chief executive officer of the association dur- 

 ing the twenty-two years which have wit- 

 nessed such an extraordinary development of 

 the scientific work of the country, paralleled 

 by the growth of the association from some 

 1,200 to over 10,000 members.
