Referee's report by John Ambrose Fleming, on a paper 'The measurement of high potential difference' by H C Leake, R Leventhorpe and C S Whitehead Recommended for publication in Proceedings, then in Philosophical Transactions. The brief abstract of the paper is not sufficient give an account of the investigation and it should be published in full. The paper is the record of careful and painstaking work, but it does not add anything of much importance to current knowledge. Subject: Physics [Published in Proceedings of the Royal Society, 1895]. 21 January 1896
