Copy letter from Herbert Rix, to the Direct Photo-Engraving Company 'In answer to yours of the 15th, kindly let us know what would be the cost of collotype as suggested by you. Would this involve printing on plate paper? On the 22nd July we paid account from you 15/- for goods supplied May 21. The Auditors require an invoice giving particulars: kindly furnish us with this by an early post. HR'. 16 November 1895
