Solution of bisulphate of mercury may be used in thesebatteries instead of the acid solution of potassium bichromate,but it does not give a sufficiently strong current for manypurposes. The disadvantages of these forms of batteries are the follow-ing: The fluid soon becomes weak and requires to be changed;the cells become leaky, and, where hard-rubber cells are used,a complete new tray or set is required when only one cell is
