One of themost convenient forms of portable cautery battery is that devisedby Dr. Henry G. Piffard, of New York, and shown in Fig. 210. 242 PRACTICAL ELECTRICITY IN MEDICINE AND SURGERY. Storage batteries give excellent satisfaction as cautery-batteries. They can be charged by attaching them to a seriesof gravity cells (ten or twelve are sufficient), and when thebattery is wanted for use it can be detached from the chargingcells and carried wherever needed. When the electrodes areattached, and the rate of discharge regulated by a rheostat, theinstrument is ready for use. In Fig. 211a storage battery forthis purpose is shown. It contains three cells, and furnishes acurrent powerful enough
