This battery is verj^ compact, portable, andcan be easily managed by any ph3^sician. It is adapted to all caseswhere galvano-cautery is applicable. (Fig. 99.) Some of the well-known galvano-cauteries of foreign make are thoseof Trouve, of Paris; Mayer and Meltzer, of London ; Down Brothers,of London, and Coxeter & Son, London. Besides the galvano-cauterybattery in surgery, the Gramm machine was enlisted also into its Hedinger, of Germany, was the first to put it into practice. It isso constructed that it can be run either by hand or motor power. Thisis a very valuable cautery for stationary purposes and where motor power.

There are other primary and secondary batteries, but the limitedspace allotted, in a work of this order, does not permit me to dilatefurther. I have already mentioned other methods of using the cautery,as by the incandescent-light tap and by rheostats. PORTABLE BATTERIES FOR ELECTRIC science of medicine owes much to the artificial sources oflight for means of examining such portions of the body as cannot bedirectly seen. As instances we may mention the larynx-mirror used byListon in 1840 and re-introduced by Czermak in 1858, and the eye-mirrorwith the help of which Helmholtz obtained for the first time a light of thestructure of the living eye, etc. As a rule, daylight or a lamp is used GALVANISM.
