Before the experiment, the frog weighed 601 grains, and at its termination 655 grains, 

 representing a gain of only 54 grains by cedema. 



After remaining unaffected for 10 min., a slow and steady contraction of the 

 blood-vessels then occurred in this experiment.

Before the experiment, the frog weighed 462 grains, and at its termination 586 

 grains. The gain by cedema was, therefore, 124 grains. 



A few minutes after contact with the blood-vessels, the Strophanthus solution pro- 



duced a gradual contraction.
