8. If a non-electric, while receiving the virtue from the rubbed tube, be made 

 to communicate with the floor of the room, or any other great non-electric 

 body, by a non-electric string, how small soever, though but a thread, the 

 virtue will not show itself, as it did before, at the extremities, where the flash 

 of light was seen. 



g. If a non-electric be ever so large, when suspended, it will receive electri- 

 city from the rubbed tube. And if 5 or 6oo feet long, when the rubbed tube 

 is applied at one end, the bodies hanging at the other end will become electrical. 

 This has been tried by several people, as well as myself. 



10. If a long non-electric string be fastened to an electric per se, and ex- 

 tended to a great distance, being supported by electric per se, to keep it from 

 touching the ground, all bodies fastened at the end of it will become electrical, 

 when the rubbed tube is applied at the other end, though the tube does not 

 touch it, but is only brought within 2 or 3 inches of it. 



Note, This string we have before called the conductor of electricity, and the 

 cat-gut or silken strings, glass tubes, or whatever kept the long string from 

 touching the ground, supporters. 



1 1 . If any of the supporters, mentioned in the last observation, be changed for 

 a non-electric supporter, the virtue will there be stopped, and taken away by that 

 supporter : but if that supporter be again supported by electrics per se, it will 

 only receive so much electricity as will impregnate it, and then the virtue will 

 go on to the end of the string, and impregnate the bodies fastened to it. 



12. The non-electric receive the greatest virtue at the end of the string, and 

 most of all, if they are wet. But the electrics per se, if long bodies, as long 

 sticks of wax, and glass tubes, only become electric at the end next to the 



string. 



13. Electrics per se will become non-electrics, if they be wet, or only 

 moistened. Thus supporters that transmit the electricity immediately, stop it 

 when wet with a sponge, or when blown through, if open tubes. And if the 

 long electrics per se, hanging at the end of the conductor, be made wet, they 

 will become non-electrics, and strongly receptive of the virtue given by the 

 robbed tube at the other end of the string. All the 6 experiments mentioned 

 in the beginning of this paper, confirm this observation. 



14. A non-electric having been impregnated with electricity, by the rubbed 

 tube, is repelled by it, till it has lost its electricity by communicating it to an- 

 other non-electric. Then being in its first state, it is again attracted by the 

 tube, which holds it till it has fully impregnated it; then it repels it again. 

 This is evident, by attracting a down feather by the tube in the air, and then 

 repelling it : so as to make it dance backwards and forwards to and from a finger
