Copy of Referee's comments by [Charles Robert] Harington, on a paper 'The action of ultraviolet radiation on proteins. I and II' by [Joseph Stanley] Mitchell and [Cecil Benjamin] Allsopp Paper reference code: B.194 and B.195 Does not recommend for publication. Refers to an article by [L Earle] Arnow in Physiol. Rev. [Physiological Reviews] in 1936. States that 'the authors are unfamiliar with modern work on proteins and amino-acids'. Highlights an insightful observation. Recommends significantly shortening the papers. [Not published]. 28 May 1938
