In some of my later models an immovable tray is placedbeneath the battery for electrodes, and a movable shelf is also provided upon which a mil-liampere-meter, the solution of table salt, and the electrodes in actual use can beset. A glasscover protects the battery from dirt when not in use. .£, coils; A, plunger; O,faradaic binding-posts:
