has in the center a porous cup containing a bar of carbon, around which is packed a mixture of manganese dioxide and coke. The top of the porous cup is sealed to keep the contents in place. The carbon is the positive pole and a rod of zinc at the side of the jar is the negative. The liquid used is a solution of ammonium chloride (sal ammoniac). This cell polarizes rapidly and is suitable for open circuit work only. It is largely used for electric bells. It needs but little attention after it is once properly charged. A modification of this cell is shown in Fig. 1.
