Page 853. For electrode processes, eq. 3 refers to the case where the concentrations of the oxidized and reduced forms are equal. The more general case of inequality of these concentrations is also given (see ref. 5h) by eq. 3 when va is replaced by E - Eo',E and EoJbeing the potential and formal potential, respectively, of the half-cell. This addition does not affect any discussion in the paper.-R. A. MARCUS.

Final paragraph: Because the solid copper iodate was in the form of the monohydrate, the entropy of water (16.7 e.u./mole) should be added, thus giving a value of 56.1 f 2 e.u./ mole for the entropy of crystalline copper(I1) iodate monohydrate, instead of 39.1 as shown.-R. 14'.
