Referee's report by George Barger, on a paper 'The heat developed by the action of caustic soda on cotton (“mercerisation”)' by Thomas Barratt and J W Lewis Sectional Committee: Chemistry Not recommended for publication in the 'Proceedings of the Royal Society of London'. The section concerning the heat of the reaction is interesting, but the applications to cotton are not relevant to the Society. Suggests the paper should be submitted to a physicist, suggests Archibald Vivian Hill. Suggests that just because a paper is communicated by Arthur William Crossley that does not guarantee it's scientific merit.
