Referee's report by James Hopwood Jeans, on a paper 'On the origin of the absorption spectra of certain types of organic compounds' by N P McCleland Sectional Committee: Physics and Chemistry No clear statement regarding publication in the 'Proceedings of the Royal Society of London'. Considers the paper 'vague and sketchy' and 'cannot feel any enthusiasm' for it. Cannot make a judgement on the paper as a chemist, but as a physicist would be surprised if the conclusions turned out to be true. If published, the author should be asked to 'explain his analysis more clearly'. [Not published] Endorsed on verso as received 2 March 1914. [April 1914]
