AN EXPERIMENTAL ANALYSIS OF OEDEMA

such behavior would result if the osmotic pressure of lymph 

 and of muscle in red-leg disease were lower than that of 

 normal resting muscle. That these predictions have been ful- 

 filled is shown by the following experiments. 



In table 7 are shown experiments in which the left gas- 

 trocnemius muscles of three normal healthy frogs were im-

Behavior of gastrocnemius muscles from normal healthy frogs, in lymph from 

 subcutaneous lymph sinuses of frogs with red-leg disease.

mersed in lymph from frogs with red-leg disease, and the 

 right gastrocnemius muscles (control) of the same frogs were 

 immersed in Ringer's solution approximately isotonic with 

 normal resting muscle. In each instance the muscle im- 

 mersed in lymph gained weight while the weight of the muscle 

 in isotonic Ringer's solution remained stationary. Also, as 

 shown by the controls in tables 8, 9, and 10, it will be ob- 

 served that muscles from frogs with red-leg disease lost
