DE THOMAS R. FRASER ON STROPHANTHUS HISPIDTTS. 



The QBdema produced in this experiment was moderate, as it was represented by a 

 gain of 70 grains in a frog whose original weight was 388 grains. 



After normal saline had passed for 19 min., and 1 : 10,000 strophanthin solution for 

 32 min., without any material change having occurred in the blood-vessels, they became 

 so rapidly contracted when 1 : 20,000 digitalin solution was passed through them that 

 the flow was reduced to one-half in G min., and was all but arrested in other 10 min. 

 (Plate XX.). 



Experiment CXLI. — Normal saline followed by solution of strophanthin in saline 

 1 : 5000 (Plate XX.).

 before the experiment, and 462 grains at its termination.
