A New Cyanide Process. James A. Yeatman of this city has made application for a patent upon a process for the extraction of gold and Mr. silver by means of cyanide of sodium solution and electrolytic precipitation. The precipitation is accomplished by the use of an insoluble anode and the metal is precipitated directly upon an alloy plate. The product will thus only need to be melted and run into bars of fine bullion, there being no amalgam to retort or zinc shavings to refine, as in other cyanide processes. In the Pelatin-Cleriprocess the metals are precipitated by electrolysis, but the precipitation occurs in the solution ieia tank and upon a bed of amalgam, and cyanide of potassium is used as the in bom Stock, foreign, solvent.

In commenting upon the announcement by the London Times that Russia and Japan are preparing to place themselves upon the gold basis, the New York Financier says: The sooner those nations get on a gold basis the better it will be for the cause of bimetalism, as it will demonstrate the failure of the single gold standard.
