The caseis placed on a base with iron legs, making itstrong. It has rollers underneath, so that it maybe easily tranpsorted about a room, or from oneroom to another, if necessary. It niaj^ also beoperated with the no volt direct incandescentlight current, the adaptation and use of whichwill be taken up in detail later. In this event,all that is necessary is a flexible cord and plugto screw into suitable sockets placed at convenient points, where you desire. ^iuilillill THE ElvECrRO-THERAPEUTlC GUIDE 59 to use the roller cabinet, A plate glass shelf below will temporarily ac-commodate the electrodes, etc., but all these should be protected from at-mosphere, to preseve their finish when not in use.

The constant current generated by a dynamo or storage battery differsin action in no essential particular from the constant or galvanic currentproduced by chemical action in some one or other of the many forms of gal-vanic cells customarily used by physicians, while the electro-motive forceis, as a rule, much less variable. The advantage to the physician of hav-ing a current supply from a central station and thereby freeing him fromthe innumerable annoyances inseperable from the attempt to keep a seriesof primary batteries in efHcient working condition, can be readily seen andappreciated by all who have worked in
