"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

"The most common and, for many purposes, the most convenient form of condenser is the Leyden jar. This consists of a glass jar, coated within and without for about two-thirds its height with tinfoil, and a metallic rod that communicates by means of a small chain with the inner coat, and terminates above in a knob or a disk." — Avery, 1895

"D is a Leyden jar, fastened to a stand in such a way that its outer armature can be insulated or connected to earth at will. The inner armature is in good metallic connection with the knob C. A horizontal metal piece A is mounted on a glass pillar, and carries another knob, which can be set at any required distance from C by means of a screw and graduation. The piece A is connected with the outer armature of the jar by a thin wire B contained in a glass tube." — Encyclopedia Britannica, 1893

"The Leyden jar and discharger. Its discovery is attributed to the attempt of Musschenbrock and his pupil Cuneus to collect the supposed electric 'fluid' in a bottle half filled with water. The bottle was held in the hand and was povided with a nail to lead the 'fluid' down through the cork to the water from the electric machine. The invention of the Leyden jar is also claimed by Kleist, Bishop of Pomerania." -Hawkins, 1917

"...consists of a glass jar coated inside and outside with tinfoil, or some other thin sheet metal, except three or four inches at top, lef uncoated for insulation between the coated surfaces. This jar is closed with an insulating cover, through which a brass rod extends to the inside coating, and terminates above in a ball." -Atkinson 1903
