Becaufe the part of their natural quantity of elec- 
tric fluid, which they had loft, is now reftored to 
them again, by the repulfion of the glafs tube forcing 
that fluid to them from other parts of the prime 
conductor : fo they are now again in their natural 
ftate. 
Withdraw ify and they will open again. 
For what had been reftored to them is now taken 
from them again, flowing back into the prime con- 
ductor, and leaving them once more eleCtrifed nega- 
tively. 
Bring the excited tube under [the threads^ and they 
will diverge more. 
Becaufe more of their natural quantity is driven 
from them into the prime conductor, and thereby 
their negative eleCtricity increafed. 
Experiment III. 
7%e prime conduct or not being eledlrijiedy bring the 
excited tube under the tajjely and the threads will 
diverge. 
Part of their natural quantity is thereby driven out 
of them into the prime conductor, and thev become 
negatively eleCtrifed, and therefore repel each other. 
Keeping the tube in the fame place with one hand 
attempt to touch the threads with the finger of the 
other bandy and they will recede from the finger. 
Becaufe the finger being plunged into the atmo- 
fphere of the glafs tube, as well as the threads, part 
of its natural quantity is driven back through the 
^ hand
