Copy letter from Robert William Frederick Harrison, to Murray Griffith, 15 Austin Friars, E.C. In answer to Griffith's letter enquiring about a report on Nile Water, Harrison cannot find that the Royal Society has ever issued one, but in 1885 a report on the Nile Delta Deposits was published in the 'Proceedings of the Royal Society'. This paper contains a reference to one by Dr Tidy in the 'Journal of the Chemical Society', volume 37, 1880. This later paper contains detailed analysis such as Griffith requires. 10 October 1902
