Letter from Charles Todd to [Henry] Dale, regarding a paper 'The photodynamic action of methylene blue on bacteriophage' by [Jean René] Perdrau and Todd Paper reference code: B.62 Has been informed that the paper he and Perdrau submitted has not been approved for publication. The paper is supposed to be an introductory note ahead of a much longer work being published, and Todd believes the referee appears to have overlooked the new findings within it. [Initially withdrawn, but later resubmitted, given the new reference B.95 and published in the Proceedings of the Royal Society of London B, 1933]. 25 July 1932
