Abstract
THIS bulletin, obtainable for a mere half a dollar, consists of reprints of the masterly series researches published by W. Mansfield Clark and his associates from 1923 onwards. Twelve pages supplementary notes have been included. The principal author, well known for his valuable book on “The Determination of Hydrogen Ions”, was quick to appreciate that Gillespie's measurements of the electrode potentials induced by bacterial reduction, published in 1920, revealed a method whereby might be possible to accumulate quantitative data concerning oxidation and reduction. The first paper outlines the theoretical aspect of the problem and shows how it is possible to express relative oxidation-reduction intensities in terms of electrode potential. For each system a constant can be found which is measure of its oxidation-reduction intensity, a matter quite apart from the capacity of a solution to oxidise or reduce. A series of substances can therefore arranged, so that when themselves in the half -oxidised or half-reduced state, each one will tend to oxidise one with a more negative constant, and to reduce one with a more positive constant.
