The frog weighed 327 grains before the experiment, and 435 grains at its termination ; 

 the gain of 108 grains representing considerable general oedema. Notwithstanding that, 

 saline alone had already been passed for 40 min., the vessels contracted very little 

 on subsequent contact with 1:100,000 strophanthin solution; indeed, they remained 

 almost unchanged after 40 min., and became only slightly contracted after 1 hour of 

 contact with this solution of strophanthin. In the curve of this experiment (Plate XX.) 

 the first 30 min. of the passage of saline has been omitted.
