The increase to the right ofthe minimum is mucli less rapid than that to the left, thedifference being due to the fact that the temperature coeff--icient of conductivitv is much greater in v;ater than in methyl o alcohl-water mixture having the sameconductingpower as pure methyl alcohol solution har. also changed . Inthis case it changes from, an alcohol of ahout 19 per centto an alcohol of ahout 30 per cent, depending on the concent--ration of the solution ^ mn1n][fmi3i]|l!lli!i:linL:iir ^. (41) Table XX.
