In another part of this work I have already said that a volta-meter submitted to the influence of an electric current for a momentbecomes capable of furnishing a current contrary to the exciting capital fact has enabled me to show, under one of its plainest forms,the phenomenon of the polarization of electrodes. The current furnished in this manner by the voltameter is a secondary. FIG. 62.—Gaston Plante Sheet. current, and the apparatus becomes a secondary element. The currentmay be said to have been furnished by the battery and returned by thesecondary element. The study of this question dates from the investi-gations by Gautherot, as early as 1801. Shortly afterward the firstsecondary battery was devised by Ritter, of Jena. Following on theinvention of the voltaic pile, it has been found that if an oblong stripof wet paper has its extremities in contact with the poles of the pile eachhalf of the slip will be electrified, and if it be removed from contact withthe pile by a rod of glass or other non-conductor its electric state willcontinue. This was observed by Yolta, and, according to Dr. Lardner(writing in 1841), was the means of suggesting to Ritter the idea of hissecondary pile, which consisted of a series of discs of a single metal,alternated with cloth or card moistened in a liquid by which the metalwould not be affected chemically.
