cally represented in figures 1, 2, 3, and 4. In these experi- 

 ments, and in all others of a similar sort, the percentage of 

 the gain or the loss in weight of the skin glove, unless other- 

 wise stated, has been estimated upon the original weight of 

 the empty skin glove at the time of its removal from the 

 body that is, before fluid ivas placed in the glove and before 

 the glove was suspended in the solution. For example, in 

 experiment 431 A (fig. 1) a gain in weight of the skin glove 

 amounting to about 475 per cent indicates that during a 

 period of forty-eight hours the weight of the fluid trans-

ported through the skin into the glove amounted to 475 per 

 cent of the weight of the empty skin glove before it was filled 

 ivith Ringer's solution and before it was suspended in the 

 solution. 



Figure 1 represents the range of behavior observed in the 

 case of three skin gloves removed from the hind legs of three 

 different healthy frogs (R. pipiens) which had been supplied 

 by a dealer about one month prior to the experiments. Each 

 skin glove, with the outside of the skin turned outward, was 

 filled with Einger's solution approximately isotonic with 

 frog's blood, and was suspended at a constant temperature in
