Abstract
MR. WOLFENDEN'S letter on this subjectl has, I regret, only recently come to my notice. I had thought that our correspondence had cleared up the points at issue. I would point out that the liberation of electricity by the action of micro-organisms during the downgrade reactions of organic compounds, as set forth in my paper,2 has been confirmed by Elema,3 Gillespie,4 Hewitt,5 and others, and my results are quoted as the starting-point for the investigations of oxidation-reduction potentials in biochemistry and bacteriology. In this paper it was emphasised that the electrical effects only occurred under conditions favourable to the growth of the micro-organisms in question.
