as before) neither the Bodies nor Ring receiv’d any 
Eledtridty. 
N.B. This was done in foul Weather, when the 
Eledricity does not extend itfelf far from the Tube : 
But in fair Weather, the Eledtrical Virtue, at the 
fame Diftance, reach’d the Iron Radii of the Ringj 
and confequently the Ring and Bodies fufpended, 
though the Virtue was not propagated along the 
Cat-gut: For if the Tube was applied a little higher 
to the fingle Cat-gut, fo as the Effluvia^ or Virtue 
darted diredlly from the Tube, did not reach the 
Ring, or its Iron Radiiy then no Virtue was commu- 
nicated to the Ring, or the fufpended Bodies, 
Experiment IV. 
I fufpended the Ring by fix Packthreads,, juft in the 
fame manner a-s the Cat-gut Strings before; but ftill 
all thofe Strings were fufpended by the perpendicular 
Cat-gut of three Foot in Length. Then all the Bodies 
receiv’d the Eledricity from the rubb’d Tube ap- 
plied to the Top of the Pyramid of Packthreads. 
Experiment . V.. 
Inftead of the perpendicular Cat-gut between the 
Pyramid of Packthread and the upper hempen String, 
1 fubftituted a Packthread ; and then no Virtue was 
communicated to the Ring, but all went up the 
hempen String, and was loft; except the Tube was 
held very near the Ring, and then it gave a fmall 
Degree of eledrical Attradion to the Ring, and the. 
Bodies fufpended at it. .
