Referee's report by Thomas Andrews, on a paper 'The specific heat of mixtures of alcohol and water' by August Dupré and Frederick James M Page Recommended for publication in the 'Philosophical Transactions of the Royal Society'. The paper is very long and fragmentary and would benefit from shortening. Refers to work of Henri Victor Regnault. Suggests the authors withdraw the paper and resubmit a fuller report at a later date. Subject: Physics and Chemistry [Published in the 'Proceedings of the Royal Society of London'] 11 June 1868
