the largest attendance in the history of the so- 

 ciety. This large attendance was due, in. part, to 

 the fact that the societies representing the bio- 

 chemists, the pharmacologists, the experimental 

 pathologists, the anatomists, the zoologists and the 

 naturalists 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 aU the biological societies had joint 

 dinners and smokers the three evenings of the 

 meeting. 



Two of the scientific sessions of the Physiolog- 

 ical Society were joint meetings with the Bioehem 

 ical and the Pharmacological societies. The sci- 

 entific program was as usual a lengthy one and 

 comprised a number of papers of unusual im 

 portance. The number and general high grade of 

 the demonstrations was also a feature of the meet- 

 ing. The following is a list of the scientific com 

 munications :
