Advantage of elevated pointed Conductors. 
EXPERIMENT XIV. 
The two clouds being charged, I took away the hand 
with the three inch ball on it, the point remained lumi- 
nous, and the moveable artificial- cloud ftill continued 
horizontal, not being attracted to the point, though there 
was now only the ftand with the pointed wire under one 
end of it, the point having carried of the electric fire as 
in the laft experiment.

EXPERIMENT XV. 
The two clouds being again charged, I replaced the 
ftand with the ball on it ; and now, inftead of taking away 
this ftand, as I did in the laft experiment, I took away 
the ftand with the pointed wire on it : the confequence 
was, that the end of the moveable artificial cloud was 
now attracted down to the ball till it came to its ftriking 
diftance, where it then difcharged its electricity on.it in a 
ftrong fpark (fee fig. 4.). The moveable artificial cloud 
then receded a little till it was charged, it then was at- 
tracted by the ball as before, till it came to its ftriking 
diftance, when it again difcharged its electricity at once, 
and fo continued ftriking and then receding to a little 
diftance as long as the two clouds were charged.
