from this equation and these experiments and the value of Ne obtained from experiments on electrolysis; for Ne is merely the amount of electricity required to separate by electrolysis one gram-equivalent of any substance from a solution. The value of ${\displaystyle \scriptstyle {\sqrt {N}}e}$ obtained from the most accurate experiments on the electrolysis of silver is ${\displaystyle \scriptstyle 1.702\times 10^{7}}$ electrostatic units. The mean value of ${\displaystyle \scriptstyle {\sqrt {N}}e}$ obtained from 1,735 displacement measurements upon nine different drops was ${\displaystyle \scriptstyle 1,698\times 10^{7}}$ electrostatic units.
