very little,, if any Attra&ion. If the Tube was held 
near the ou tilde of the Hoop, it attracted j but ftrongeft,

the Hair-Line the Hoop was fufpended by. To this 
Hoop there was tied a ielfer Hoop of about a Foot and

Hoop, the lower Part of the lower Hoop attrafted- 
ftrongly, and when held near the upper Part of the 
lower Hoop,, but very weakly j but when held near 
the lower Part of the lower Hoop y there was.no
