✦ Synopsis

Votes aJl~{ Co3/z¢//eJtts. 49 r two anodes between which is placed a circular metallic disc mounted oll a gun-metal spindle, and capable of being rotated. The disc is partly out and partly in the bath, and so comes in contact with tile air and the electrolyte. The part of the disc outside the electrolyte comes in contact with two scrapers, one on each side, which scrape off the spongy deposit and depolarize the surface. The anodes are either in the form of plates, or in receptacles containing coarse powder. When the cathode has a sufficiently thick layer of metal it is taken to a bath of molten metal similar to that deposited, and the electrolytic deposit is melted in the bath, and then the cathode is taken back to the elec.. trolyzer. Mr. Tommasi claims that polarization is entirely done away with, that the metal deposited is removed as the deposition proceeds, and that the density of the liquids in all parts is the same.
