Abstract

SEVERAL new primary batteries are in the field, and there are more to come. An iron cell invented by Dr. Pabst of Stettin is finding great favour in Germany. Its electrodes are carbon and wrought iron dipping into a solution of ferric chloride. It is practically unpclarisable and self-regenerating. Itjworks at the expense of iron and of the oxygen of the air, which is absorbed into the liquid, whilst ferric oxide is deposited at the bottom of the cell. Its electromotive force is about .78 of a volt. The Pabst cell ought to prove of value for domestic electric lighting, as its internal resistance is low and its constancy remarkable.
