Referee's report by Cyril Norman Hinshelwood, on a paper 'Slow oxidations at high pressures I—Methane and ethane, II—Methyl alcohol, ethyl alcohol, acetaldehyde, and acetic acid' by Dudley Maurice Newitt and P Szego Sectional Committee: Chemistry Recommended for publication in the 'Proceedings of the Royal Society of London'. The reactions conditions are not defined, so the results are only of qualitative interest. However, as the high-pressure condition is interesting and the products isolated are important, the results do have value.
