Referee's report by John Hall Gladstone, on a paper 'On supersaturated saline solutions' by Charles Tomlinson Not recommended for publication in the 'Philosophical Transactions of the Royal Society'. The paper covers the existing literature well, and contains interesting experiments. However, the thinking is difficult to follow, and the conclusions unsupported. Suggests the author withdraw the paper, reduce the literature review and controversial parts, and reconsider the conclusions. An abstract has already been published in the Proceedings and some of the results have already appeared in the Philosophical Magazine. Subject: Physics and Chemistry [Published in the Philosophical Transactions of the Royal Society] 3 August 1868
