In all the experiments the reservoirs were placed at a height of 7\ inches above the 

 frog. The temperature was recorded at the beginning and during each experiment, and 

 in the whole series it ranged between 57° and 62° F. As in many of the experiments 

 considerable general oedema occurred, the frog was weighed before and at the termination 

 of each experiment. 



It was found that normal saline could usually be passed through the blood-vessels for 

 more than an hour without producing any important change in their diameter. This 

 absence of change is well illustrated in the following experiment.

A gain in weight of 70 grains occurred in this experiment ; before the experiment 

 the frog weighed 455 grains, and at its termination 525 grains.
