suspended in the same solution at 16 C. The behavior of the 

 glove (458 A), with the outside of the skin turned outward, 

 was typical of that observed in most experiments of this 

 character. It gained weight continuously from the time it 

 was first suspended in Einger's solution (fig. 8, second day). 

 A comparison of the behavior observed on the first and on 

 the second days clearly still further emphasizes the fact that 

 water is more readily absorbed by the skin through its inner 

 surface than through its outer, and that the direction in which

water is transported through the skin in opposition to os- 

 motic pressure depends upon which surface of the glove is 

 turned inward or outward. 



As all of the experiments mentioned in the preceding pages 

 were made on skins removed from living frogs, we may infer 

 that the behavior observed, at least during the first few hours 

 of the experiment, represents the average condition one 

 would find in the power of the living skin both to absorb 

 water and to transport water through itself in opposition to 

 osmotic pressure. It has been observed in the majority of 

 instances that water is transported through the skin in a
