Mr. Hawksley constructs three kinds of batte¬ ries A Voltaic battery, with any required number of cells, from 15 to 100; a Faradaic battery; and a combined battery, uniting both Voltaic and Faradaic currents. The Tibbits Voltaic Battery* has its cells arranged in the interior of a mahogany case, and in use they are hidden from view and from danger, but I now partially expose them by removal of the tray for holding the sponges and accessories. Their con¬ necting wires are brought across the under surface of the element board, which is made to move upon hinges that, when necessary, the cells may be exa¬ mined, but at other times this element board is held in position by a bolt, and it should never be B.

The poles, N and P, are seen through holes cut in the element board. G. Key by which the current can be shut “off” or “on,” without change of position of the conductors.
