THE AMERICAN ASSOCIATIONZFOR THE ADVANCEMENT OF SCIENCE 
THE WASHINGTON MEETING 
Tue sixty-third meeting of the American Association for the Advancement of Science 
was held at Washington, D. C., December 27 to December 30, 1911, under the presidency 
of Dr. Charles E. Bessey, of the University of Nebraska. The meeting was the most suc- 
cessful in the history of the association, both from the point of attendance and from the en- 
thusiasm shown. Beautiful weather prevailed throughout and the people of Washington, 
including the many scientific men connected with the various governmental bureaus, did 
everything in their power to make the stay of the visitors pleasant and profitable. The total 
registration of members of the association was 1,306, whereas the largest previous registra- 
tion was that at the third Boston meeting, when the total was 1,140. A conservative esti- 
mate of the actual number of members of the association present in Washington would 
place the number at 1,800 and there were doubtless as many as a thousand more present 
who are members of affiliated societies and not members of the association itself. The fol- 
lowing is a list of affiliated and other scientific societies which met in Washington at the 
same time. 
Astronomical and Astrophysical Society of America. Geological Society of America. 
American Physical Society. Paleontological Society of America. 
American Society of Biological Chemists. American Association of Economic Entomologists. 
American Chemical Society. Entomological Society of America. 
Association of American Geographers. American Breeders’ Association.
