Abstract
IN the course of recent work in the Physical Laboratory of this University on hydrogen overpotential at a mercury cathode, large changes of electrode potential were found to take place, and considerable over-potential was produced with depositions of hydrogen corresponding to very much less than a monomolecular layer. It was felt that these observations were of considerable interest, as they showed that, for the overpotential so obtained, any theory requiring gas in bulk (such as a surface tension theory, or one requiring a continuous film offering resistance to the current) would be untenable.
