"Bring a metallic sphere postively charged near an insulated cylindrical conductor with hemispherical ends and provided with pith-ball and lined thread electroscopes as shown. The divergence of the pith-balls shown electrification at the ends but not at the middle of the conductor." -Avery 1895

"Suspend two egg-shell conductors as shown. Be sure that the shells are in contact. Bring an electrified glass rod near one of them, and slide one of the loops along the supporting rod until the shells are about 10 cm. apart. Hold the electrified rod between the shells. It will attract one and repel the other, showing that thye are oppositely electrified." -Avery 1895

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
