Copy letter from Herbert Rix, to George Gabriel Stokes, President of the Royal Society 'Dear Sir, We are sending cards to Messrs Cory & Sykes. Will you please pay me the £20-2-0 not pay it at the rooms. This will prevent confusion; as all those who present invitation cards will be charged for in the bill by the Manager. I enclose scraps for the Anniversary Address. I take it for granted that I need not supply any items about the Catal. Sci. Papers ['Catalogue of Scientific Papers]. Yours obediently H Rix'. 18 November 1889
