to excite its EleCtricity, I applied it near the End C 
of the Firft Bar; and the eleCtrical Virtue ran along 
the Two Bars, and impregnated the Ball G, as ap- 
peared by its attracting the Thread hanging from the 
Stick //, at about Three Inches Diftancc. After- 
wards I feparated the Tubes, in the manner that they 
appear in the Figure; and the Electricity was com- 
municated to the Ball but faintly when the Bars 
were an Inch and an half afunder, and not at all when 
they were Two Inches and an half afunder. But this 
was owing to the moift State of the Air ; for, when 
the Air is very dry, the Virtue will jump Six or Nine 
Inches; but when the moift Particles, that float in the 
Air, are attracted by the Bars, the Virtue will reach 
but a little Way ; though, if that Moifture be fixed 
upon any Body, which (being an EleCtric per fe) 
would not conduCt the EleCtricity applied to its End, 
the Virtue will be carried from one Bar to another as 
well as if they had touched, as will farther appear by 
the next Experiment. 
Experiment II. Fig. 2 . 
Having feparated the hanging Bars fo far afunder, 
that the EleCtricity could not jump from the one to 
to the other, (viz. about Three Foot) I laid upon 
their End the fmall Tube T> E, having wiped it very 
dry : Then, applying the rubbed Tube to C, the Virtue 
flopped at ; and neither the Bar E F, nor the Bali 
G, received any EleCtricity, the Thread H being 
attracted by neither of them. But, having blown 
through the Tube, the Moifture of the Breath changes 
it from an EleCtric to a Non-eleCtric; and then the 
Virtue of the rubbed Tube runs along freely from C
