354 PHILOSOPHICAL TRANSACTIONS. [aNWO 173Q. 



Exper. 4. — I suspended the ring by 6 packthreads, just in the same man- 

 ner as the cat-gut strings before ; but still all those strings were suspended by 

 the perpendicular cat-gut of 3 feet in length. Then all the bodies received 

 the electricity from the rubbed tube applied to the top of the pyramid of pack- 

 thread. 



Exper. 5. — Instead of the perpendicular cat-gut, between the pyramid of 

 packthread and the upper hempen string, I substituted a packthread ; and then 

 no virtue was communicated to the ring, but all went up the hempen string, 

 and was lost ; except when the tube was held very near the ring, and then 

 it gave a small degree of electrical attraction to the ring, and the bodies sus- 

 pended at it. 



Exper. 6. — Having again suspended the ring with the bodies and pyramid 

 of packthreads to the perpendicular cat-gut, I tied a packthread to the ring, 

 and carried it horizontally about 20 feet from the ring; and having fastened 

 to it a cat-gut string, 3 feet long, I gave it an assistant to hold : then applying 

 the rubbed tube to the end joining that cat-gut, the electricity was commu- 

 nicated to the ring, and all the suspended bodies, as appeared by applying the 

 white thread near them, which was attracted by every part of the ring, and all 

 the bodies. 



Experiments made before the Royal Society, Feb. l6, 1737-8. By the Same.

Exper. \ . — I applied the rubbed tube to a burning candle, and it had no 

 manner of effect on the flame ; but as soon as the candle was blown out, it 

 attracted the smoke at 4 or 5 inches distance. 



Exper. 1. — A horizontal packthread, of about 18 feet in length, being ter- 

 minated by the cat-gut strings, of 3 feet long each, and hung, towards one 

 of the ends of the packthread, on it a candlestick with a lighted candle in it ; 

 then applying the rubbed tube to the other end of the packthread, the candle- 

 stick attracted the thread, and it was also attracted by the candle, but not 

 within 2 or 3 inches of the flame ; but as soon as the candle was blown out, 

 the thread was attracted by every part of it ; nay, even the wick, when it was 

 quite extinguished. 



Exper. 3. — I suspended a wax candle in the same manner, and the experi- 

 ment succeeded the same ; only the electricity came not so near the flame in 

 the wax as in the tallow candle. 



Exper. 4. — I hung an iron wire, \6 feet long, horizontally by two cat-gut 

 strings at its ends, about 3 feet long each, and bent down the wire from the
