Advantage of elevated pointed Conductors. 8 43 
moveable artificial cloud was horizontal. I then placed 
the hand with the point on it at the diftance of eighteen 
inches, and directly under the ball at the other end (fee 
fig. 5 .) : on charging the artificial cloud, the point was 
luminous; and that end of the moveable artificial cloud 
which was three inches above the ball c was attracted 
down to it, then receded from it about one inch,' and 
then the artificial cloud kept conftantly ftriking to it, as 
long as it continued to be charged. On ceafing to charge 
the artificial cloud, it was found immediately after, that 
the point had carried off alrnoft all the electric fire. 
EXPERIMENT XIX, 
Every thing remaining as in ,the laft experiment, and 
the artificial cloud being charged, I took away the ftand 
with the point, and placed in its Head the ftand with the 
three inch ball on it, exactly at the fame diftance as 
the point: then inftantly that end of the moveable arti- 
ficial cloud, which had continued to be attracted down 
near to the artificial cloud, was repelled from it, and at 
the fame time the other end was attracted by the three 
inch ball till it came fo near as to difcharge its electricity 
on it in a ftrong fpark. The end of the moveable arti- 
ficial cloud then receded from the three inch ball,
