Abstract
II. THE experiments were made in a bell-jar, containing the terminals, which could be gradually exhausted after having been rilled with air or other gas. One of the terminals was fixed to the bottom plate, the other could be adjusted to any distance from it by a rod sliding through a stuffing-box in the glass cover. The foot of the stand was insulated by a disk of ebonite, on which it stands. One such bell-jar is 91/4 inches (23.4 centims.) high, and 57/8 inches (14.9 centims.) in diameter; its cubical content, ascertained by covering the open ends with glass plates and filling with water from a graduated measure, was found to be 3,787 cub. centims.
