DR THOMAS R. FRASER ON STROPHANTHUS HISPIDTJS. 



Onlv slight oedema occurred ; the frog before the experiment having weighed 385 

 grains, and at its end 432 grains, representing a gain by oedema of 47 grains only. A 

 little oedema of the extremities was observed at 36 min., but it never became marked. 

 The contraction of the blood-vessels proceeded more rapidly than in the previous experi- 

 ment, but even at the end of 30 min. of contact with this strong solution of Stroph- 

 anthus, the vessels were sufficiently open to admit of a moderate flow through them.

The frog weighed 354 grains before the experiment, and 401 grains at its termina- 

 tion. The gain of weight was only 47 grains, indicating but slight oedema. The amount 

 of contraction produced in the blood-vessels was much the same as in the previous 

 experiment.
