Third referee's report by Alfred Charles Glyn Egerton, on a paper 'On the thermal decomposition of acetaldehyde and ethylene oxide' by R V Seddon and Morris William Travers Sectional Committee: Chemistry Recommended for publication in the 'Proceedings of the Royal Society of London', but requires further consideration. Suggests the paper be sent to Edmund John Bowen or Ronald George Wreyford Norrish for comment. Refers to work of Cyril Norman Hinshelwood, with whose work the current paper contradicts in places. Presentation of the paper has improved. Gives thorough criticism of the experimental method.
