We get $$\gamma$$ from the table of graduations to be $$\frac{1}{255}$$, and find from our equation (p. 346)

This is for unit potential gradient on the C.G.S. system, and gives for a gradient of 1 volt per centim. a velocity of

This is the velocity of the copper ion in a solution of 0.1 grm. equivalent per litre, while deduced for infinite dilution

The next case I shall describe is that of a pair of salts whose 0.1 grm. equivalent solutions have specific resistances which are nearly the same. Mr. kindly supplied me with a long list of conductivities reduced to comparable units,
