830 Mr. n a fane’s Experiments to Jhevo the 
beyond the furface of the three inch and half ball. This 
ball and Item, with the pointed wire to it, I fixed to a 
ftand covered with tin-foil ; having a good metallic com- 
munication with the earth, I placed this ftand fo that the 
point was diredtly oppofite to the fide of the artificial cloud, 
and exactly at five feet diftance from it : then, on charg- 
ing the artificial cloud, the greateft ftriking diftance from 
the ball c to the ball of four inches diameter, on the re- 
ceiving rod d, was found to be fixteen inches and feven 
tenths..

EXPERIMENT VIII. 
Every thing continued as in the laft experiment, only 
now I drew the wire out of the ball and Item, fo far that 
the point projected nine inches beyond it: on charging 
the artificial cloud, the greateft ftriking diftance now was 
found to be but fix inches and eight tenths. 
Now, in order to fee how far a point, or different fized 
balls fixed on the ftand, and having a very frnall fepara- 
tion in the metallic communication with the earth, 
would vifiblv a6t to carry off the ele£tric fire of the arti- 
£cial cloud, I made the following experiment.
