Corollary I. 
From the different State of the pendulous Silk and 
Threads at the fame time under the fame Circum- 
ftances, the former being attradled while the latter 
is repelled, it follows, that a mere Vibration of the 
Parts of the Tube is not fufficient to account for the 
'^L\tQinzz\’Th£nomena i which appears farther from 
the two contrary States continuing fome time, and 
from the fame Piece of Silk being at once part in a 
State of Repulfion, part in a State of Attradlion. 
Corollary II. 
That fome Bodies immediately receive and imme- 
diately part with the Eledric Efflunjia^ but that others 
are fome time before they receive it, or receive 
enough of it ; and \vhen they haye received enough 
of if, part with it more unwillingly. 
Corollary III. 
That any light Body, as a Feather, after touching 
or nearly approaching the Tube, muft fly from it; 
Upon Contadl or a near Approach, it faturates itfelf 
with thz'EXtdinz Ejfluviay and by this means becomes 
itfelf Eledrical (as is plain from its coming to all 
other Bodies too large to come to it) 5 and confe- 
qucntly, from the foregoing Experiments, is in a 
State of Repulfion with regard to the Tube. As 
foon as it touches any other Body, it lofes its ac- 
quired Eledtricity, and therefore may be attraded as 
at firft.
