Referee's report by John Tyndall, on a paper 'Introductory research on the induction of magnetism by electrical currents' by James Prescott Joule Does not state whether he thinks the paper should be published. Provides observations and suggests modifications which could be made, but adds that his suggestions may not be entirely based on resounding knowledge. He has no clear comprehension of Joule's experimental arrangements. Subject: Physics [Published in Philosophical Transactions, 1856] 25 July 1855
