The law of charging eleflrics, ap- pears to be, that the fum or whole quan- tity of eleftricity at both furfaces, is al- ways either accurately or nearly the fame. The following experiments, made with the patent eleftrical machine, fet this impor- tant principle in an obvious point of view. 8. Experiment L Takeoff the ends of the two conductors G and R, and the in- cluded jars will be vifible, the wires with the bails being ftuck in the cork of j[iach. Hang the chain b on the knob H of R, and turn the cylinder. The jar in G will not, in thefe circumftances, be- come charged, excepting by means of a fmall quantity of electricity, which will pafs from the ball of the jar into the air. But again, if the knuckle, or any other condudtor, be applied near the ball of the jar in G, during the turning, fparks will iffue from it in abundance, ftrong and fre- quent at firft, but gradually lefs and lefs fo
