Copy letter from Robert William Frederick Harrison, to Professor Arthur Schuster, Fellow of the Royal Society The Sectional Committee on Physics and Chemistry will be glad of Schuster's opinion as to whether the accompanying paper by Professor [Walter Noel] Hartley, 'Experiments on the Flame Spectrum of Carbon Monoxide', should be published in the 'Proceedings', and if so what modifications, if any, are desirable. Shall be glad of an early reply. 15 April 1897
