Experiment III. 
To each of the Ends of two Threads, fiifpended 
as at firft, a Feather being tied, the two Feathers ma- 
nifeftly receded from each other: And when three 
Threads had each a Feather at their Extremities, the 
middlemoft became Stationary, and the two outer 
went off on each hand. 
Experiment IV. 
I fufpended afterwards two, three, four and five 
blue filk Strings- by Loops, upon one crofs blue Silk, 
and found the feverai Experiments fucceed in the 
fame manner as in Threads j except that they remained 
a longer time before they appeared in a State of Re- 
pulfion, receded from one another more llowly, and 
continued much longer in the repulfive State, after the 
Tube was removed. 
Experiment V. 
This done, I made feverai Experiments, by mixing 
Silks of different Colours, and Silks and Threads of 
different Colours, and fufpended them by Turns upon 
Sil ksof different Colours,whence arofe feverai different 
^hanomena-, which I fhall not take Notice of here j 
but I muft not omit mentioning, that upon fufpend- 
ing two black Silks at the before-mentioned Diftances 
from each other, upon a fcarlet crofs Silk, they did 
not only open and recede from each other at the 
Bottom confiderably, but when the Tube was held 
under, ran or jump’d away from each other, to the 
very Ends of the crofs red Silk that fupported them, 
taking two, three, or more Jumps from each other.
