Copy letter from Herbert Rix, to M P A Merlateau, a Sainte-Sabine, par Beaumont, Dordogne In reply to Merlateau's letter of 9 February addressed to the President, before any paper can be brought before a meeting of the Royal Society it must be endorsed by a Fellow as being suitable. No paper previously communicated to another academy can be read at a Royal Society meeting and from Merlateau's letter it appears the paper sent had already been sent to the Academy at Paris. Rix therefore returns the paper enclosed with thanks. 18 February 1892
