MATHEWS. 



be referred to an opposite action on the same structure. Not 

 knowing of Tschirwinsky's work, I had already performed simi- 

 lar experiments on the lymph flow, comparing it wath pancreatic 

 flow on vagus stimulation and after pilocarpine. I found (Ex- 

 periment V that atropine temporarily neutralizes the large 

 increase in lymph flow w^hich occurs concomitant with increased 

 panceas secretion during rythmic stimulation of the vago-sym- 

 pathetic after division of the cervical cord, and also neutralizes 

 the increased lymph flow due to pilocarpine.
