Supplemental referee's report by George Carey Foster, on a paper 'On the limit of the liquid state' by J B Hannay Recommended for publication in the Proceedings of the Royal Society of London. Discusses the experimental method, and there is no objection to their printing on the Proceedings. Suggests a distinction between gas and vapour be made in the supplements. Suggests omitting the conclusions, as the experimental part is the important and valuable part of the paper. Subject: Physics and Chemistry [Published in the 'Proceedings of the Royal Society of London', 1882] 28 November 1881
