"This apparatus shows the rotation at once of a magnet and of a movable conductor. The rotating pieces are the magnet sn, which is tied to the copper peg at the bottom of G by means of a piece of string, and swims round the vertical current buoyed up by the mercury in G, and the wire DE, which is hinged to D by a thin flexible wire, and swims round the pole of the vertical magnet n's'." — Encyclopedia Britannica, 1893

"Faraday used in his experiments two identical pieces of apparatus, which were vertually two spherical Leyden jars. The outer coating EF was divided into two hemispheres, which could be fitted together airtight. The lower hemisphere F was fitted to a perforated stem, provided with a stop-cock G, so that it could be screwed to an airpump while the apparatus was being exhausted, and afterwards screwed into a foot H. The upper hemisphere was pierced by a tube, into which was cemented a shellac plug B. C is a metal wire passing down through B, which supports the hollow metal sphere D, forming the inside armature, and carries the metal ball A, by means of which D can be charged and discharged." — Encyclopedia Britannica, 1893

"Faraday's ice pail experiment. An ice pail P connected with gold leaves of an electroscope C, is placed on an insulating stand S. A charged conductor K, carried by a silk thread, is lowered into the pail, and finally touches it at the bottom. While it is being lowered the leaves of the electroscope diverge farther and farther, until K is well within the pail, after which they diverge no more, even when K touches the pail or is afterwards withdrawn by the insulation thread. After withdrawal, K is found to be completely discharged." -Hawkins, 1917

"We may compare currents by the quantities of a given electrolyte which they decompose in a given time. Faraday's voltameter is intended for this purpose. As compared with a galvanometer, the voltameter has the obvious disadvantage that it cannot measure a current at once, but only after the current has been flowing for some time." -Hazeltine, 1894
