peptone per kilo that a prolonged fall of pressure is obtainable, 

 and even with this quantity the pressure again resumes its 

 normal within an hour. These facts seemingly suggest more 

 or less pronounced difference in the chemical structure of the 

 proteose and peptone molecules, a point which we have taken 

 occasion to emphasize in other connections.! 



* All of the samples of antialbumid were dissolved by the aid of a little 

 dilute ammonia except in Experiment XIV, where dilute sodium carbonate 

 was used.
