Copy letter from an unknown correspondent, to Messrs Simmon & Tullige, Pleasant Grove, York Road, Holloway The Messrs did not send their complete account in time so the cheque herewith had to be drawn for £5-13-6. The correspondent also sends 18 shillings and six pence from petty cash to balance the account and asks for separate receipts. The enclosed bill appears to be for the Royal Institution. 4 November 1887
