conditions. These muscles lost weight when immersed in 

 Ringer's solution approximately isotonic with normal resting 

 muscle. 



In table 9 are shown experiments in which the gastrocne- 

 mius muscles of a frog with red-leg disease were immersed 

 in lymph obtained from the same frog. In one experiment 

 (experiment 661) the lymph was taken from the subcutaneous 

 lymph sinuses, and in the others from the coelom. It will be

observed that the muscles when first placed in lymph either 

 gained slightly or remained stationary in weight, and that 

 the controls lost weight when placed in Ringer's solution ap- 

 proximately isotonic with normal resting muscle. 



Jacques Loeb ('98) has stated that when a frog's muscle 

 is immersed in a 0.7 per cent solution of NaCl, to which a 

 trace of acid has been added, the muscle takes up and holds 

 water. This phenomenon forms the central idea of the 

 colloid-chemical theory of Martin Fischer; hence it is inter-
