Advantage of elevated pointed Conductors, 8 a 7 
two balls was about ten inches ; the hilling noife then 
ceafed, and the light difappeared on the inch ball. It 
now began to ftrike again, and continued ftriking to the 
inch ball all the time it was very gradually removed, till 
the diftance was about fourteen inches eight tenths; and 
fometimes would continue to ftrike to ftxteen inches, and 
three tenths. 
This ftriking to the ball ceafing, and then beginning 
again, when the artificial cloud is ftrongly charged, is a 
fact which I believe has not been taken notice of by any 
one before; I fhall have occafion to fpeak of it again in 
fome of the following experiments. 
EXPERIMENT III. 
The apparatus remaining as in the laft experiment, I 
changed the ball of one inch diameter, and in its place 
fcrewed one of three tenths of an inch diameter. This 
fmall ball -was alfo placed nearly in contact with the 
ball c : on charging the artificial cloud, the electric fire 
ftruck to this ball of three tenths, and continued ftriking 
to it whilft it was very gradually* removed to the diftance 
of half an inch ; beyond that, it would not ftrike to it. 
But the ball was luminous all the while it was removed 
beyond the ftriking diftance as far as thirty-three inches.
