203. LYONS, MORRIS, 143 Suffolk Street, Birmingham — Inventor.
Apparatus and specimens to illustrate the process of bright electro-plating, gilding, electro-engraving, and deposition of copper for the formation of tubes. This process differs from others, in at once depositing the metal in a bright state, requiring no after polishing. Hence it is particularly adapted for embossed works of art. The economy of this process consists in its requiring less battery- power, and a smaller consumption of the precious metal.
[Bright electro-plating has been effected by mixing a few drops of the sulphuret of carbon with the silver or gold solution in the precipitating trough.- R. H.]
