case, the glove, with the inside of the skin turned outward, 

 was filled with isotonic Ringer's solution and suspended in 

 the same solution at room temperature. At the end of the 

 first hour of suspension, the gain in weight amounted in one 

 glove (exper. 409) to 23.8 and in the other (exper. 412) to 

 47.5 per cent. After the first hour, however, each glove began 

 to lose weight, through the transport of water from the glove 

 through the skin outward. At the end of twenty-four hours' 

 suspension in Ringer, the loss in one case amounted to 119 



U-lS 



(exper. 409) and in the other to 70.5 per cent (exper. 412). 

 If we compare the behavior of these two gloves filled with 

 Ringer's solution with that of an empty glove (exper. 409, A, 

 fig. 6) taken from the hind leg of one of these same frogs 

 (409), also with the inside of the skin turned outivard, we 

 observe that while the empty glove gained weight (31.6 per 

 cent) during the first two hours of its suspension in Ringer's 

 solution, after this time its weight remained practically sta- 

 tionary. In this instance the empty skin glove contained no 

 fluid which could be transported from the glove through the 

 skin outward and, since no fluid was transported through the
