like the EleBricals per fe. Thus an Iron, Bar ;fur- 
pended by a fiiken Thread, an Hair Rope, or a dry 
Cat-gut, when an excited Ele^ric per fe is brought 
near it, will both attack and fend out its Effluvia to 
a ELon-eleStric held near it ,* as appears in the Dark 
by the Light coming out at the End of the Bar. 
5. An Ele£irical per fe lofes its excited Virtue in 
communicating to the Non~eIe£iricali and the 
fooner, the more of thofe Bodies are near it. Thus 
in moift Weather the rubb’d Tube holds its Virtue 
but a little while, becaufe it adts upon the moift Va- 
pours that float in the Air,* and if the rubb’d Tube 
be applied to Leaf- Gold or Brafs, laid upon a Stand, 
it will a£t upon it much longer, and more ftrongly, 
than if the fame Quantity of Leaf-Gold is laid upon 
a Table, which has moxz NoTP-eleBrical Smizz^ than 
the Stand. 
6. When a Elon-elePirical is fufpended by, or 
only touches an EleBrical per fcy it receives the 
Properties of an EkBrical per fe from a rubb’d 
Tube or Wax, &c. This appears by the Fire that 
fiafhes from the Fingers of a Man fufpended by Hair- 
Ropes, or who ftands upon a Cake of Refln, when 
he has receiv'd Virtue from the rubb’d Tube. 
7. The Virtue which a Elon-eleBrical receives 
from a rubb'd Tube, runs on to the moft diftantPart 
of the* fufpended Body from the Place where the 
Tube is applied, and feems to becolleded there, from 
whence it flalhes in the Park, fnaps, and exerts its 
AttraAion upon the Thread of Trial; though as the 
Virtue runs along, it fometimes fhews itfelf in other 
.parts of the fufpended Non~eleBricat
