THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE 

 THE ATLANTA MEETING 



Under the presidency of Dr. Edmund B. Wilson, professor of zoology in Columbia 

 University, the sixty-fifth meeting of the American Association for the Advancement of 

 Science, and the twelfth of the " Convocation week " meetings, was held in Atlanta from 

 December 29, 1913, to January 3, 1914. 



It seems to be almost impossible to obtain an accurate record of the attendance, chiefly 

 because the members of the affiliated societies do not register. The number actually regis- 

 tered at headquarters was 324 members of the association, 54 members of afiiliated societies 

 and 16 delegates. Perhaps the total attendance, based to be sure on estimation, was about 

 500, a very good number when one remembers that Atlanta is rather out of the beaten 

 track of tourists, but even if the number in attendance was not as great as at some of the 

 previous meetings, and notwithstanding the rainy weather, the admirable arrangements 

 and the enthusiastic reception accorded were more than compensation. With that charac- 

 teristic hospitality of the south the people of Atlanta extended to the visitors a welcome 

 that will long be remembered.
