Referee's report by John Hopkinson, on a paper 'The influence of stress and strain on the physical properties of matter.— Part III. Magnetic induction (continued).—The internal friction of nickel, and cobalt, studied by means of magnetic cycles of very minute range' by Herbert Tomlinson No clear statement regarding publication in the 'Philosophical Transactions of the Royal Society'. The paper is long and tedious and doubts it would be read, but does not wish to prevent the publication of results by a competent observer. Subject: Physics and Chemistry [Published in the Philosophical Transactions of the Royal Society, 1891] [1889]
