All improved batteries are, therefore, constructed with amalga-mated zinc. 234. Sulphate of Copper Battery .—Another form of battery,called the sulphate of copper battery, from the fact that a solution of sul-phate of copper (blue vitriol) is used as the exciting liquid, is represented byFig. 68. It consists of two concentric cyhnders of cop-per, C, tightly soldered to a copper bottom, and a zinccylinder, Z, fitting ia between them. Two screw-cupsfor holding the connecting wires are attached, one tothe outer copper cyhnder, and the other to the zinc. The principal imperfection of the galvanic battery isthe want of uniformity in its action. In ah the variousforms, the strength of the electric current excited con-stantly decreases from the moment the battery actioncommences. In the sulphate of copper battery, espe-cially, the pow
