The power of electricity is in- creafed by the number and flze of the globes to a certain degree, but by no means in proportion to their number and fize; therefore as the bodies to be ekCtrified will contain only a certain quantity of electricity, of which more largely hereafter; when that is acquir¬ ed, which is fooneft done by a num¬ ber oi globes, the furcharge is diflipat- ed as faff as it is excited. VI. After the globes had been a few times ufed, I found myfelf matter of a much greater quantity of eleCtrical power with much lefs labour to myfelf, than when I ufed only tubes. I could attract and repel light fubfiances at a much greater diftance than before ; fire fpirits of wine, camphire, and all other fubftances, whofe vapours were inflam¬ mable, with great eafe and at any di¬ ftance, with non-eleCtrics placed upon originally-
