The use of steel in preference to copper may be credited to Mr. Perkins and the engraver Warren. Warren annealed his plates at a high temperature in earthen boxes packed with pounded oyster-shells. The practice in the Bank of England, as modified by Oldham, is to anneal at one time four east-iron boxes, each containing from three to six steel plates, surrounded on all sides with fine charcoal, mixed with an equal quantity of chalk, and driven in hard.
