Referee's report by James Chadwick and Charles Galton Darwin, on a paper 'Deviation from the Coulomb law for the proton' by Herbert Fröhlich, Walter Heinrich Heitler and B Kahn Sectional Committee: Physics Recommended for publication in the 'Proceedings of the Royal Society of London'. Is doubtful of the conclusions drawn and assumptions made by the authors. Note by Charles Galton Darwin recommends the paper for publication in the 'Proceedings of the Royal Society of London'. Does not fully trust the results, but seems right. 'Still no worse than others of same kind'.
