• Of the oxidation-reduction reaction of organic compounds, the case, in which the undissociated molecule of an organic acid is reduced at the more positive potential than the corresponding dissociated anion and the equilibrium concentration of the reducible form at the electrode surface is kept by the diffusion process and the recombination reaction at the electrode surface, has been taken into consideration. Under such conditions, the general formulae for the polarographic current-voltage curve have been derived, and the special case which involves the " kinetic current" has been investigated. The theoretical discussions on the limiting current and the shift of the half-wave potential with the change of <I>p</I>H have been carried out. Moreover, the results obtained have been applied to interpret the properties of the wave of pyruvic acid observed by R. Brdicka. A considerably good agreement between the experimental data and the theoretical results has been obtained, and it is probably said that the properties of the various polarographic waves and the mechanism of the electrode process can be investigated by the analogous treatment mentioned above.
