Referee's report by William Cawthorne Unwin, on a paper 'Iron and steel at welding temperatures' by T Wrightson Recommended for publication in the 'Philosophical Transactions of the Royal Society'. The experiments were conducted using instruments rarely available to the physicist. Some of the references in the footnotes are incomplete. Suggests omitting figure one, as it has already appeared in the Journal of the Iron and Steel Institute. Refers to a paper by Frederick Joseph Bramwell, to which reference should be made in the paper. Subject: Physics and Chemistry, Applied Sciences [Published in the Philosophical Transactions of the Royal Society, 1895] 15 March 1895
