If, for instance, (the platec being turned out of the way by the hinge d), the in-strument a be charged with positive electricity, its leaveswill diverge, and the leaves of b will also diverge withthe same electricity ; on… … dually diverge with negative electricity ; if it be broughtback to its original position, they again collapse ; if itpass that point, and be brought close to a, the leavesdiverge with positive electricity. If now the two platesare brought into contact, the electricity of the one willnot exactly…
