Plunge Cautery Cautery Battery Rheostat Dry Cell Cautery Any kind of cautery battery is used to burn or cauterize the tissues,wherever such treatment is desired.

The cells of a cautery battery are few innumber, generally from three to eight, but the elements aie very large, incomparison with those of the galvanic battery, thus creating a current ofvery large volume or amperage, and of very low pressure, or Cautery Knives and Points. Fig. 1601 shows a number of platinum knives and points, which ex-perience has proven to be best and adapted for cautery work. What is a storage battery, and its use? A storage battery consists of two elements, an electrolyte and a jar, ora number of them, connected together. The elements are both lead. Thereis no current, on account of the similarity of the elements, until a currentof electrification has been passed through the battery, which changes one ofthe elements to oxide of lead, by electrolysis of the water in the the current begins for the same reason that it begins in any one of the elements is partially prepared in advance by perforat-ing it with holes and filling the holes with oxide of lead. This kind of bat-tery may be used for cautery work, or for running such machinery as fansetc. It is heavy and not easily moved about. It is also an expensive kindof battery. This prepared element is called a grid. 36 THE ELECT
