Referee's report by Samuel Walter Johnson Smith, on a paper 'On critical hydration pressure of solid salts' by William Robert Bousfield Sectional Committee: Physics and Chemistry Not recommended for publication in the 'Proceedings of the Royal Society of London'. The experiments are interesting but the results are not 'of sufficient novelty' for publication. Due to travel, cannot check the results and opinion against the literature.
