1 piece of glass, on the upper part of which is cemented a brass socket D, furnished
1 with a spring tube E; the wire F moves in this tube, so that the ball G may be set
2 at a convenient distance from the ball H. The end I of the bent piece of glass is
3 also furnished with a spring tube, which slides upon the wire K, communicating
4 with the inside of the bottle. / To use this bottle, place the ball H in contact with
5 the conductor, or connect them together by a wire, and then charge it in the usual
6 manner. Now, if a wire proceeds from the ball L to the outside coating, the bottle
7 will be discharged whenever the fluid has acquired sufficient force to pass
8 through the space of air between the two balls; consequently the shock is stronger
9 in proportion as the distance between the two balls is increased. / It is obvious,
10 that when the electrometer is thus connected, it acts in the same manner as a
11 common discharging rod, and forms the communication from the outside to the
12 inside of the bottle; with this difference only, that the distance of the end which is
13 to communicate with the inside may be limited and regulated. The shock may be
14 given to any part of the human body by introducing that part of the body into the
15 circuit which is made between the outside und inside of the bottle. This is
16 conveniently effected, by connecting one director by a piece of wire with the
17 electrometer, and the other to the outside of the bottle; then hold the directors by
18 their glass handles, and apply the balls of them to the extremity of the parts
19 through which the shocks are to be passed.“

21 Die Entwicklung dieser Einrichtung als Elektrometer geht auf Timothy Lane
22 zurück, vgl. ErxH, 565,16 – 21 und VNat 4, 294,1 – 3 und die zugehörige Anm. –
23 Ein ähnlich funktionierendes Instrument befindet sich in der Historischen
24 Sammlung des I. Physikalischen Instituts (Inv.-Nr. H72). Vermutlich handelt es
25 sich dabei um ein zwischen dem 1. Juli 1850
