a Motion about its own Axis in the fame Di- 
redion; but after two or three Turns generally ftopt, 
and turn’d the contrary Way, which fecm’d to arife 
from the untwifting of the Thread. 
Experiment VIII. 
A Thread about a Foot long, was fufpended from 
an horizontal Line of Packthread, parallel to it an 
excited Tube placed cred in a Stand, the Thread 
approached the Tube, and continued in a State of 
Attradion : A Thread of the fame Length, fufpended 
from a filk Line, vibrated backward and forwards two 
or three times, being firft attraded, and then repelled, 
and continuing fome time repelled j but upon joining 
the Top of the Tube, by a Packthread going round it, 
to the Loop of the Thread, the Thread continued 
conftantly in a State of RepuHtqn, fhewing no Ten- 
dency to Attradion. 
Experiment IX. 
Two black Silks, about the fame Length with the 
Thread in the preceding Experiment, were fufpended 
by Loops from an horizontal red filk Line, at the 
Diflance of about half an Inch from each other ; 
upon holding the excited Tube under them, the Silks 
fwelled out from one another, and then jump’d away 
on each Hand to the Diftance of two Feet. 
Experiment X. 
A circular Board of nearly the fame Diameter with 
the eledric Cake, was fufpended horizontally by 
fix filk Lines, tied to one filk Line which was brought
