Adopted in France by the "Paris, Lyons and Mediterranean," the "Northern," the "Middle," the "Western," and the "Eastern" Railroad Companies. In England, in Austria, in Belgium, in Holland and in Italy. The Positive Pole is composed of a plate of Carbon set into a mixture of powdered per Oxide of Manganese and Carbon, and hermetically sealed in a porous vase. The Negative Pole is composed of a plate or pencil of amalgamated Zinc. The two Poles are set in a solution of Sal Ammoniac and water, contained in a glass jar. As the Zinc is indefinitely preserved without alteration in the Sal Ammoniac, and as the per Oxide of Manganese is insoluble in this liquid, no internal chemical action takes place when not in use. The Electro-motive power of Grove being 100, this is 75, and Daniels 50; or three cells of this battery are equal to four cells of the Daniels. ITS ADVANTAGES MAY BE ENUMERATED AS FOLLOWS: 1st. RUNNING EXPENSES REDUCED TO A MINIMUM, 2d. THE ENTIRE ABSENCE OF ACIDS. 3d. ITS GREAT CLEANLINESS. 4th IMPOSSIBILITY OF GETTING OUT of Order, 5th DOES NOT FREEZE. 6th. WILL LAST WITHOUT RENEWAL from one month to several years, according to use, at the end of which time the porous cells can be renewed at a moderate cost. A number of cups have been in use by the Western Union Telegraph Company, on a closed circuit, since November 26, 1872, nothing but water having been added since they were first set up.
