Ostwalds Electrochemical Researches. Ill This result is identical with that already stated; for, ifequal conductivities of the various acids are exhibited atequally proportional dilutions, then the dilution-exponents,which can be represented as logarithms of the dilutions (withthe base 2), must show constant differences. The form of thecurve is indicated by the results obtained ; it runs asymptoticbetween the axis of p and a parallel placed at a distanceequal to 90 units, and appears to be symmetric to right andleft and also above and below. The maximum of increase,as already observed, lies at 45, where the curve shows As we have here undoubtedly to do with a natural law, noexception to which is shown by any of the results obtainedfor 90 to 100 monobasic acids, it is reasonable to supposethat the curve must be capable of representation by a fairlysimple analytical expression. At first sight a tangent-functionis suggested. The results were therefore reduced so that themaximum fell at the value 90 ; they were then regarded asangles, and the corresponding tangents were found. Thetangents, however, formed not an arithmetical but a geome-trical series ; the logarithms of the tangents gave approxi-mately constant differences, they increased proportionatelywith the dilution-exponents.
