Copy letter from Herbert Rix, to Signore Professore Pier Andrea Saccardo, R Orto Botanico, Padova, Italy Rix acknowledges receipt of Saccardo's letter of 1 May, which will be laid before the Catalogue Committee at their next meeting. The Society is already preparing a supplementary catalogue to contain titles from very many serials which have not been hitherto indexed. Should Saccardo be able to send any list of Serials which he has noticed as being un-indexed, this would be of assistance in completing the supplementary catalogue. 7 May 1895
