that, when highly eledrified, they give the intire 
fhape of the leg; and when brought near the face, 
or any naked part of the body, there is a fenfation 
felt, as if a cool wind was blowing upon that part. 
When the two white, or the two black, are held to- 
gether by the extremities, they repel one another, 
and form an angle, feemingly of 30 or 35 degrees. 
4 0 . — When a white and a black flocking are pre- 
fen ted to each other, they mutually attrad, with a 
force anfwerable to the degree of eledricity they have 
acquired : when brought within the diflance of three 
feet, they ufually incline towards one another : within 
two and a half, or two feet, they catch hold of each 
other ; and when brought nearer, they rufli together 
with furpriling violence. As they approach, their 
inflation gradually fubfides ; and their attradion of 
foreign objeds diminifhes : when they meet, they 
flatten, and join as clofe together, as if they were fo 
many folds of filk ; and then the balls of the eledro- 
meter are not affeded at the diflance of a foot, nor 
even of a few inches at certain times. But what 
appears mod extraordinary, is, that when they are 
feparated, and removed at a fufficient diflance from 
each other, their eledricity does not appear to have 
been in the leafl impaired by the fhock they had in 
meeting. They are again inflated, again attrad, and 
repel, and are as ready to rufh together as before *.

another, their attractive and repulfive force decreases, with regard 
to foreign objeds, but increafes furpriflngly, with regard to each 
other , and that their eledricity fuffers no diminution from the
