as in the preceding Experiment. Yet the Silk, 
whether the long Packthread was added or not to the 
fhorter Arm of the Cane, continued conftantly at- 
traded towards the Tubcj but upon putting a fhort 
Silk only fix Inches long, in the fame Circumftances, 
it would, after fome time rubbing the Tube, turn 
into a State of Repulfion, the upper Part firft bending 
from the Tube, and the lower Part towards it, the 
tipper Bending hill increafing till the Whole was re- 
pelled 3 and, which is remarkable, the upper Part or 
Bending, upon the Approach of the Finger, or any 
Body not impregnated with Eledrical Effluvia, flying 
towards it, and the under Part or Bending rather 
feeming to fly from it, till the Whole was faturated, 
and in a State of Repulfion with regard to the Tube, 
and then any Part of it would come to the Finger, 
or any other Body, not made Eledrical. It is proper 
to add here one more Difference remarkable between 
the Thread and Silk : The Thread in a State of Re- 
pulfion touched with the Finger, would immediately 
fly towards the Tube ; but the Silk in the fame State, 
after touching feveral times, ftill continued in a State 
of Repulfion, and would not be attraided till fqueezed 
from Top to Bottom between the Finger and Thumb, 
once, and fometimes two or three times. And far- 
ther, the Thread would immediately turn again into 
a State of Repulfion, whereas the Silk, after the Vio- 
lence committed by the Thumb and Finger, being 
attradfed to the Tube, would not without a good 
deal of rubbing the Tube, be repelled again. 
N. B. The Silk was untwifted, and about one 
fourth part of the Thicknefs made ufe of.
