I have sent by rail this evening your plates and 2 prfs of each. I attended to the burnishing as requested.
Are you aware of the new patent of Mr Joubert for coating copper plates with a steel surface thus enabling you to take off as many as a steel plate. Should you be coming to town I can shew you the effect or I can have one of your plates surfaced The cost is 4d pr inch
