THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT! OF SCIENCE. 

 ITHACA, N, Y., JUNE 28 TO JULY 3, 1906. 



REPORT OF THE GENERAL SECRETARY. 



The fifty-sixth meeting of the American Association for the Advancement of Science 

 was held at Ithaca, New York, June 28-July 3, 1906. This meeting was peculiar in 

 being an extra meeting in the summer, the winter meeting at New Orleans having been 

 held only six months before, and a winter meeting being planned for New York six 

 months later. As a consequence of the fact that it was an extra meeting, there were no 

 presidential addresses, no election of officers, except to fill vacancies, and there was but 

 little action of any kind taken by the council. 



The registered attendance of the association members was 232, and 94 members of the 

 American Chemical Society were known to be present who were not registered as members 

 of the association, making a clearly ascertained total attendance of 326. Other informa- 

 tion, derived from the registration of four affiliated societies, indicates that the total 

 attendance was about 400. As to attendance, the meeting was intermediate between the 

 two meetings next preceding, namely, at New Orleans and at Philadelphia. 



The following table shows the registered attendance by sections, and the affiliated 

 societies which met at Ithaca :
