Lectures on nervous diseases from the standpoint of cerebral and spinal localization, and the later methods employed in the diagnosis and treatment of these affections . Fig. 143.— Cell.—The zinc rod (the one withits rheophore attached) is shown as immersed in a solutionof ammonic chloride. The carbon element is seen to projectslightly above the porous cup, in which, when the cell isproperly prepared for action, it is packed with peroxide ofmanganese and afterward covered with Fig 144.—Grenets Cell.—Theflasks come of all patterns,according to the taste of thevarious makers.

In the formhere depicted the zinc islowered into the fluid by astraight handle. This is thecell most used in portableelectrical apparatus. It ischeap, eflScient, and easilyrepaired. Kenioving theelements and replacing themovercomes polarization incase the current grows weakfrom that cause. Somemakers place the zinc inadrip-cup when the cell is not in use. set in action, to .07 after the spurt. The plates are raised and loweredby a windlass. The extent of immersion can thus be graduated. Thisform of element is known as a plunge batter^. Fullers Cell.—A porous cup containing zinc, mercury, and water isplaced in a large glass jar containing red-acid fluid, in which a largecarbon plate is immersed. The mercury keeps the zinc elements are not removed when the cell is not in action. Thisform of cell is perhaps the best one yet devised to run the faradaic partof a cabinet
