An international system of electro-therapeutics : for students, general practitioners, and specialists . izeof the various parts of the cell, or of the cell as a whole, and depends solely on the materials employed in itsconstruction. On account of the constancy of theDaniell cell, which is caused by electro-motive force, in the practice it may betaken as a unit and can be compared withothers. The British Association hasadopted a unit differing very little fromthis one, and has given to it the name ofvolt. The cell in which the electro-motiveforce is exactly equal to the volt differsbut slightly from that of Daniell, The Gravity Battery.—This batteryis a simple modification of the Daniell,designed to dispense with a porous takes its name from the fact that in itthe zinc and copper sulphates are sepa-rated by their difference in density. Oneform of this battery is shown in Fig. 46. This cell always keeps inbetter condition if a closed circuit be maintained through a high resist-ance when the battery is not in use. The Grove Battery.—The Grove battery consists of a cleft cylinder. Fig. 46.—Gravity Battery. A-260 BLETER.
