The cylinder machine is represented in Fig. 262, a a being a glass cylinder, which can be turned rapidly by the multiplying wheel, b b. At c is a piece of silk, and on the rear part of the cylinder is the rubber. At d is the prime conductor.
381. Experiments.—Many experiments may be tried with the electrical machine. I will cite a few of them:
If pith balls be attached to the prime conductor, as seen in Fig. 261, they will stand out from each other as soon as the machine is worked, because they are both charged with the same kind of electric fluid.
Let a small figure with its head covered with hair be placed upon the prime conductor. As soon as the conductor becomes charged with electricity the hair stands out, as represented in Fig. 263, for the same reason that the pith balls diverged in the previous experiment.

So, also, if you place on the conductor a figure having attached to it strips of tissue-paper, they will diverge in the manner shown in Fig, 264.
