Referee's report by John Tyndall, on a paper 'Further inquiries concerning the laws and operation of electrical force' by William Snow Harris Not recommended for publication in the 'Philosophical Transactions of the Royal Society'. Considers the author to be mistaken in his reasoning. Suggests, however, that the Council not put too much weight on his opinion, and defers to the second referee if he should come to a different conclusion. Subject: Physics and Chemistry [Published in the Proceedings of the Royal Society of London, 1864] 21 November 1864
