"The best method for comparing resistances with great accuracy is the modification of Wheatstone's bridge introduced by Kirchhoff. KL is a platinum-iridium wire, DK and HL are stout copper terminals to which it is soldered, DAE, EGH, FBS are stout copper pieces with binding screws and terminals for mercury cups, by means of which resistances R, T, U, S can be inserted at D, E, F, H. A, B, and G are binding screws for the battery wires and one end of the galvanometer wire." — Encyclopedia Britannica, 1893

The Wimshurst Machine is an electrostatic device to generate high voltages. "It consists of two circular glass plates, mounted on a common spindle, and capable of rotation in opposite directions with equal speeds. Each plate carries twelve or sixteen strips of thin sheet-metal, fixed radially at regular intervals apart ... At the extremities of the horizontal diameter of the plates the main conductors are placed, insulated on glass or vulcanite pillars." -Hazeltine, 1894
