concentrations the maximum was reached earlier, while 

 in the lower concentrations it occurred later. It is evident 

 that as the concentration increases, the rise in resistance 

 is more rapid and the maximum point is passed more 

 quickly. If the concentration be sufficiently increased,

Fio. 22. — Curves showing net electrical resistance of Laminaria affardhii in sea water con- 

 taining Tarious amounts of HCl, as shown by the figures attached to the curves. Each 

 curve represents a single experiment. All readings were taken at 18° C. or corrected to this 

 temperature. Each curve represents a single typical experiment. 



the period of increased resistance becomes less and less, 

 until it becomes difficult to detect it. The relation between 

 concentration and changes in resistance is better shown 

 in Fig. 23. 



Experiments with acetic acid also showed a rise 

 in resistance.
