Referee's report by William Davidson Niven, on a paper 'Alternate current measurement' by W E Sumpner Sectional Committee: Physics and Chemistry Not recommended for publication in the 'Philosophical Transactions of the Royal Society', suggests publication in the Proceedings instead. Suggests omitting the first, mathematical part, and reducing part four. Considers the paper too long, especially when the author's previous publications are taken into account, parts of which the current paper reproduces. [Published in the 'Proceedings of the Royal Society of London'] Endorsed on recto as received 27 November 1907. [January 1908]
