The initialelectro-motive force of the Leclanche cell varies from to volts, andthe internal resistance from about to 2 ohms. There are several modifications of the Leclanche cell on the market,each one possessing an advantage or a disadvantage over the of these, as the prism Leclanche, the closed Leclanche, Leclanchewith carbon cup, are shown in Figs. 56, 57, and 58. Among the open-circuit batteries there are several known to us ofthe Roberts peroxide battery, the sulphate-of-mercury battery, and theFitch chlorine battery. They all have their special
