SOME FEATURES OF THE CHICAGO 



MEETING OF THE AMERICAN AS- 

 SOCIATION FOR THE ADVANCE- 

 MENT OF SCIENCE AND OF THE 

 ASSOCIATED SOCIETIES, 

 DECEMBER 27. 1920, 

 TO JANUARY i, 1921 



The Chicago meeting will be the seventy- 

 third meeting of the association. It will be 

 one of the larger and more comprehensive 

 meetings, which are scheduled to be held 

 every fourth year. It promises to be a 

 greater meeting than any earlier one. Every 

 American interested in science or education 

 should attend if possible and should do all 

 in his power to insure the success of the 

 meeting for every branch of scientific and 

 educational work. 



Dr. L. O. Howard, Chief of the Bureau of 

 Entomology, of the United States Depart- 

 ment of Agriculture, is president-elect and 

 will preside at the Chicago meeting. He has 

 been permanent secretary of the association 

 for twenty-two years, during which the mem-

 from 1,729 to nearly 12,000. The meetings 

 held during his secretaryship have been in-

The address of the retiring president, to be 

 given at the opening general session on the 

 evening of December 27, will be by Dr. Simon 

 Flexner, Director of the Eockefeller Institute 

 for Medical Research. 



There will be two other general sessions at 

 the Chicago meeting planned to be of interest 

 not only to all scientific workers and all mem- 

 bers of the association but also to the general 

 public. One of these general-interest sessions 

 will be devoted to an illustrated lecture on 

 High-Power Fluorescence and Phosphores- 

 cence, by Professor Robert W. Wood, of the 

 physics department of the Johns Hopkins 

 University. The other of these sessions will
