Copy letter from Herbert Rix, to Messrs Harrison & Sons, St Martins Lane Rix sends two reminders, firstly, the plates in 'Philosophical Transactions [of the Royal Society]' are to be distributed through the volumes not all put at the end, and secondly he shall want some separate copies of the list of distribution. Asks if the Messrs are awaiting anything else to finish the index numbers, and when they might have the volume out. 5 January 1893
