III. AMERICAN PHYSIOLOGICAL SOCIETY: 

 TWENTY-SIXTH ANNUAL MEETING 



A. J. Carlson, Secretary 



The twenty-sixth annual meeting of the American Physiological 

 Society was held at the University of Pennsylvania and at the Jef- 

 ferson Medical College, December 28-31, 1913. One hundred and 

 eighteen of the members of the Society were present at the meeting. 

 This, the largest, attendance in the history of the society was due, 

 in part, to the fact that the societies representing the biochemists, 

 pharmacologists, pathologists, anatomists, zoologists, and natural- 

 ists met in Philadelphia at the same time. This is a most excellent 

 plan, and should be made a fixed policy of the biological societies. 

 The members of all the biological societies had Joint dinners and 

 smokers the three evenings of the meeting. 



Two of the scientific sessions of the Physiological Society were 

 Joint meetings with the Biochemical and Pharmacological Societies. 

 The scientific program was as usual a lengthy one and comprised a 

 number of papers of unusual importance. The number and general 

 high grade of the demonstrations was also a feature of the meeting.
