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. 137.—A SimpleGalvanic Element. (AfterErb.) ^/, zinc element; 0<, carbon or copperelement. The fluid is composed of diluted sulphuric acid or a solution of some of the A the circuit is open, in B it is closed by a wire connecting the elements. The arrowshows the direction of the current outside of and within the cell. relative potentials is for the current to flow from the body having thehighest potential to that possessing the lowest potential, thus tending toestablish an equilibrium between them. In a galvanic cell, the elementmost corroded by the fluid of the cell has the highest potential (positiveelement). The difference in equilibrium between the potentials of twobodies regulates the intensity of what is known as the electro-motiveforce of the bodies selected; because the want of equilibrium is theforce which starts the flow of an electric current in all cases. The sizeof the elements has nothing to do with it. The simplest form of a galvanic (^ell consists of
