The increase of weight by oedema was 111 grains; the frog having weighed 323 

 grains before the experiment, and 434 grains at its termination. As represented by the 

 rate of flow, the blood-vessels were practically unaffected for nearly an hour by this 

 solution of extract (see Plate XIX.). A corresponding experiment with digitalin (Experi- 

 ment CXLV.) gave a very different result, for in less than 15 min. the flow through the 

 blood-vessels was almost arrested by the extreme contraction that had been produced 

 (Plate XIX.).
