Fig. 13. — Curves of net electrical resistance of Laminaria agardhii in 1793 c.c. NaCl 0.52 

 if +207 c.c. CaCk 0.279 M with the addition of 0.01, 0.02, and 0.03 U NaOH. The per- 

 centages were calculated on the basis of the net resistance of the control. All readings were 

 taken at 18° C. or corrected to this temperature. Each curve represents a single experiment 



less when they are combined with trivalent anions than 

 when combined with univalent. 



The writer* has found that OH is more effective than 

 any other anion in producing a fall in resistance. Since
