The caustic battery MEDICAL ELECTRIC HEATING AND LIGHTING. 269 first devised was that of Middledorpf, described in hisclassical work on Galvano-caasty in Operative Medicine,published at Breslau in 1854. On the continent the com-binations of Bunsen and Stohrer, in France Bunsens, andnow Trouves, and in England Stohrers modified by thelocal dealers, are the forms in use. In this country thebattery of the Galvano-faradic Company, Piffards, Byrnes,the Partz Companys (Fig. 91), Queens (Fig. 92), andothers, are those employed. The first named is composedof large zinc-carbon elements (Fig. 90), immersed in abichromate of potash solution, which is kept agitated bythe bellows to prevent polarization and to maintain thechemical activity. Piffards battery is composed of large Fig zinc-carbon elements, which are contained in cells ot vul-canite, and can be suspended on a movable arm screwedinto the box. When lowered into the fluid, the top of theelements, which is made of hard rubber, contains twolateral bars supporting them, and which permits a rockingmotion to keep the exciting fluid agitated. This is a moreefficient combination than that of the Galvano-faradic 270 ELECTRICITY IN SURGERY. Manufacturing Company. Still more effective is the batteryof Dr. Byrne (Fig. 91), which consists of small elementsunited for quantity, thus opposing a larger surface to theaction of the exciting fluid than can be effected by merelylarge plates. This battery consists of zinc-carbon cellsin a case six inches long, nine inches high, and five inches Fin. 92.
