Considerable oedema occurred, and the frog, which before the experiment weighed 

 324 grains, gained 92 grains in weight. As this strong solution did not produce con- 

 traction more rapidly or to a greater degree than the less strong solutions used in the 

 immediately preceding experiments, another experiment was made with a solution of the 

 same strength, but, as will be seen below, the results were the same. 



Experiment CXXXIII. — Normal saline followed by solution of extract of Stroph- 

 anthus in saline, 1 : 1000.

In this experiment much oedema occurred, causing an increase in weight of 153 

 grains, in a frog which before the experiment weighed 324 grains. 



To render the comparison between the effects of Strophanthus anddigitalin even more 

 distinct than by contrasting, as has been done, separate experiments in which similar 

 solutions of each substance had been used, two experiments were made, in which after a
