THE AMERICAN ASSOCIATION FOR THE 

 ADVANCEMENT OF SCIENCE 

 SECTION K AT THE BOSTON MEETING 

 The sectional committee decided to hold one 

 session, and to devote this to the discussion of a 

 subject of general interest (especially to the 

 entire field of physiology and experimental medi- 

 cine ) , and to hold this meeting in conjunction 

 with the American Physiological Society. The 

 subject " Internal Secretion " was selected, and 

 the following program was adopted;"^ all the 

 papers were by invitation: 



TUESDAY, DECEMBER 28, 1909, 2:30 P.M. 



Joint meeting with the American Physiological 

 Society, Lecture Room, Building B, Harvard Med- 

 ical School. 



Address of the retiring chairman: "Chemical 

 Regulation in the Animal Body by Means of 

 Activators, Kinases and Hormones," William H. 

 Howell. 



Symposium on Internal Secretion 

 " A General Pieview of the Chemical Aspect of 



Internal Secretion," by R. H. Chittenden. 



" The Comparative Physiology of the Adrenal 



Bodies," by Swale Vincent. 



' Professor Swale Vincent was unable to attend 

 the meeting.
