The two metals of the battery, copper and zinc, are smTOunded by electrolytes, the tendency of which is to pass toward the opposite pole.

Physiology. 28 ADVANCED LESSONS IN PRACTICAL PHYSIOLOGY conductors, such as are presented by animal tissue, invariably leads to a polarization of the current. The two metals of the battery, copper and zinc, are smTOunded by electrolytes, the tendency of which is to pass toward the opposite pole. Thus, the positive ions, Cu and H, progress toward the cathode, whereas the OH and SO4 pass toward the anode, which inside the cell is the zinc. Presently the copper plate becomes covered with bubbles of H, which place a high resistance in the path of the current and eventually neutralize it. This phenomenon is known as polarization. A similar action takes place at the points of contact between the electrodes and the tissue. It may be prevented by the use of the so- called non-polarizable electrodes. Those devised by DuBois-Reymond consist of zinc terminals immersed in a solution of zinc sulphate. A.
