Copy letter from Herbert Rix, to Messrs Drake & Gorham, 2 Princes Mansions, Victoria Street, S.W. Rix asks the Messrs to consider this letter as officially asking them to undertake the inspection of the Royal Society's electrical plant at cost of £5 a year. Rix will lay the Messrs account before the Treasurer and call his attention to the statement that the actual cost to the Messrs of the electrical work has exceeded their estimate. 7 October 1887
