It is not without interest in this connection that pilocarpine, 

 contrary to atropine, increases lymph flow. This was first ob- 

 served by Tschirwinsky.^^ My own experiments have yielded 

 a positive result generally, but not invariably. In all cases the 

 dogs had divided cervical cords, and generally divided vagi. 

 They were all under artifical respiration. The lymph was 

 measured in cc. for equal intervals of time.
