obvious from Fig. 4 that the molecular concentrations of NaCl, CaCla, 

 and LaCls, which depress the viscosity to the same level are approxi- 

 mately in the ratio of 3 : 2 : 1 . Thus when the effect of NaCl and CaCh 

 is plotted over the same concentration of the CI ions the curves for 

 the salts become identical (Fig. 5), and the same would be practically
