ction the twoparts of the discharging conductor are usually brought in contact.As the two parts, K and K, become oppositely charged, they may beseparated farther and farther apart, and discharges between the twoextremities, in the form of sparks and brushes, occur at intervals. 454 ETHER DYNAMICS. which increase with an increase of distance. By the addition ofLeyden jars, which also heoome oppositely charged, the amount ofcharge previous to each discharge is increased, and consequentlythe energy of the discharge and the brilliancy of the spark areincreased, though the discharges are less frequent. As the plate rotates, the two inductors are kept constantly andoppositely charged, and as two opposite carriers (n and n for ex-ample) are about to leave the inductors the following takes place :At n the positively charged inductor acts through the glass upon thecarrier and comb, attracting and binding the — E and repelling +E.Similar action takes place at n, but with opposite signs.

<i^^ repelled charges unite through the conductor A B and neutralizeeach other, leaving the carriers n and n charged respectively with—E and +E. As n and n move away from the inductors theircharges become free, and on reaching the brushes C C they com-municate a portion of their charges to the brushes to make goodany losses by leakage or otherwise which the inductors may sustain.We are now able to see how the charges of the inductors are re-ceived and maintained. We now turn our attention to the discharging conductor. Thetwo inductors act inductively upon the two parts K and K of theconductor, charging K with -l-E and K with — E.

Thus mechanical energy hecomestransformed into electric energy, or the energy of ether strain.^ The above is a partial description of the action of this mac
