e electrolyte, the greater the surfacefor corrosion and current strength. As we cannot get large elements into asmall cell, therefore the size of the cell makes a great difference in the out-put of electrification, or current strength or amperage. The accompanying sketch shows four cells connected together in par-allel for current strength, (amperage). Here we have four small cells allalike, each with a certain voltage and amperage, but by connecting all thezincs to one wire and all the carbons to another wire while we have not in- 34 THE EI.HCTRO-THERAPEUTIC GUIDE creased the voltage at all, we have increased the amperage four fold, be-cause we have the equivalent to one large cell with just four times the cor-rodable elemental surface. This method of connection is called multiple,or parallel, and is the method used when it is desired to pass heavy cur-rents through slight resistance, and therefore, according to Ohms law re-quiring low voltage. This plan is employed in cauterj^ work.

CELLS VvlPJtD ANA PfRCS What is a catttery battery, and its use? A cautery battery is one where the cells are connected in parallelfor amperage, and the resulting current is compelled to pass through a wirewhose resistance is great enough to heat it red hot. It is used for any pur-pose that requires cautery. If a wet battery, the zincs should not be al-lowed to remain in the electrolyte, except when the battery is in use.
