 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 8 has found that OH is more effective than 

 any other anion in producing a fall in resistance. Since
