Excerpt from Journal of the Institution of Electrical Engineers, 1899-1900, Vol. 29: Including Original Communications on Telegraphy and Electrical ScienceThe first practical application of the dynamo to the arts of life was made directly by your Honorary Member to the electro-deposition of metals from their solutions (1867 - 80) his dynamos, both in their two polar and self-exciting multipolar forms, soon superseding the voltaic battery in the principal electro-plating and electro-typing establish ments in this country and abroad. They were also largely employed (1868) in the electrolytic process of refining copper invented by Mr. James B. Elkington, and for the like purpose by the Mansfeld Mining Company, Saxony Your Honorary Member has since shown that the principle underlying the electrolytic process of refining copper, and on which its commercial success depends, is the indefinite increase of the electro-chemical forces from quantities indefinitely small, as the current from a single voltaic cell will electrolyse copper-sulphate solutions in an indefinite series of electrolytic cells (manchester Memoirs, vol.
