The bath usedis a solution of a salt of the metal to be deposited. The cyan-ides of gold and silver are generally used for gilding and sil-vering. Many of the base metals require to be electro-coppered firstin order to secure the adhesion of the gold or silver. The mag-neto-electric machine has almost replaced the voltaic batteryfor electrotyping and electro-plating purposes. For ordinary purposes, however, the Smee battery, which con-sists of two plates of zinc (Fig. 4=), between which is a lead
