The subsequent experiments were made with the platinum 
diaphragms “25 M asunder, the specific gravity 1042 and the 
remaining conditions the same as in the experiments above re- 
corded. 
It will be observed that the resistance is pretty nearly in the 
tio of the diminished length of the layer of liquid in the case 
of the hydrochlorates. The want of precise correspondence was 
ascribed to the presence of chlorine upon the platinum plates pro- 
ducing the effect of so-called polarization. The odor of'chlorine 
was remarked in the experiments with the hydrochlorates.
