By thefe Experiments we fee that Animals receive a 
greater Quantity of Ele&rick Effluvia, and that they 
may be conveyed from them feveral Ways at the fame, 
Time to confiderable Diftances, wherever they meet 
with a PaiTage proper for their Conveyance, and there 
exert their Attracting Power. ' 
In thefe Experiments, befides the large Stand above- 
mentioned, I made ufe of two fmall ones, which, as I 
found them very ufeful, it may not be improper to de- 
fcribe them. The Tops of them were three Inches 
Diameter ; they were fupported by a Column of about 
a Foot in Hight, their Bafes of about four Inches and a 
half: They were turned of Lignum vit te j their Tops 
and Bafes made to skrew on for Convenience of Car- 
riage. Upon the Tops were palled white Paper. 
• When the Leaf-Brafs is laid on any of thefe Stands, I 
find it is attrafled to a much greater Hight than when 
laid on a Table, and at leaft three Times higher than 
when laid on the Floor of a Room. 
June 20, I made the following Experiment, flee- 
ing that the Attraction and Repulfion is as Jtrong , 
if not Jl ranger, and that the Effluvia may he car- 
ried to great Lengths, without touching the Line 
hy the Tube. 
There was taken a Line of Packthread 131 Feet in 
Length } it was fupported on two crofs Lines of blue 
Silk j the Diftance of thefe Lines was near eighteen 
Feet. About four Feet below one of thefe Lines, 
was put up another Silk Line of the fame Colour : To 
this, was tied one End of the Packthread ; at the other . 
End the Ivory Ball hung ; the Line was returned over 
x the 
V;
