Copy letter from Robert William Frederick Harrison, to Mr A E Holmes, London Society of Compositors, 7-9 Bride Street, Ludgate Circus, E.C. Harrison acknowledges their letter of the 31st October referring to the printing of the International Catalogue, by which he assumes they mean the International Catalogue of Scientific Literature. He is unaware of any changes having been made to its printing, but will refer to the Director of the Catalogue and present the matter to Professor Joseph Larmor and other Officers of the Royal Society when they next meet. A postscript reports that Harrison has spoken to the Director, who assure him no changes have been made and it is still printed in London. Holmes must have been misinformed. 1 November 1907
