Copy letter from Herbert Rix, to Professor Michael Foster, [Royal Society] 'Dear Sir, I am vexed to find that the printers, after all my efforts, have inserted the wrong advertisement. They have promised to insert in to-morrow's "Times", at their own expense, a corrected list. The fault was entirely theirs. The Catalogue Sub-Committee have met this afternoon. H Rix'. 16 January 1894
