Detailed referee's report by Arthur Schuster, on a paper 'Researches in absolute mercurial thermometry' by Sidney A Sworn Recommended for publication, but it is hard to decide between publication in full in the Philosophical Transactions, or in part in the Proceedings. The unfortunate death of the author means changes cannot be made. The paper is controversial in character, and sometimes unintelligible. Gives criticism of the methods and processes. Refers to work of Charles Chree. If the author was still alive, would recommend the paper be revised, but this is not now possible. The paper cannot be easily reduced without omitting important information. Subject: Physics and Chemistry [Published in the 'Proceedings of the Royal Society of London'] Endorsed on verso as received 7 October 1899. [October 1899]
