Wollastons battery being cumbersome and unwieldy,Mnncke, Young, the illustrious Faraday, and others im- THE VOLTAIC BATTERY AND ITS DERIVATIVES. 19 asrined various ingenious arrangements for ioming a largenumber of cells in a small volume. In Munekes arrangement, the parts where the elec-trodes of zinc and copper are soldered together are placedvertically; they are divided into two series, the one fit-ting in the other as Fig. 7 represents. This battery, and the one arranged by Faraday, which. Fig. 7. differs from it very slightly, were employed for severalyears in laboratories, as the whole battery could be im-merged in one trough, which was very convenient. Theyare completely put aside to-day. SAND BATTEEY. This battery is composed of a trough made of teak,divided into ceils by partitions of slate or of wood; tomake it water-tight it is coated internally with marineglue. A plate of amalgamated zinc placed in one cellis joined to a plate of copper in the adjoining cell, andresting, at their point of contact, upon the partition; thecells are then filled with sand saturated with acidulatedwater. This battery is to-day abandoned, but it presented 20 SINGLE-LIQUID BATTERIES. many practical advantages. It was used for a long timein the telegraph service, needing no attention for severalweeks at a time, and was much more easily moved fromone place to another, than batteries wherein the liquidmight be spilled when carried about.
