Description | Harrison responds to Gradenwitz's letter of 22 March to state that the cost of preparing electros illustrating Dr Russell's paper would cost, on average, nine pence per block; so with 16 blocks forming the 3 plates, the total cost would be around 12 shillings, but this would be reduced if electros of fewer figures are required. The sums mentioned only cover the cost of preparing the electros, with the costs of carriage to be added. |
