83S Mr. nairne’s Experiments to Jhew the 
EXPERIMENT XIII. 
I firfl put this moveable artificial cloud into an hori- 
zontal pofition, and placed it fo that the brafs on which 
the axis refted was in contact with the end of the artifi- 
cial cloud b. Then, under each of the hollow cylinders 
ee, I placed a Hand gg, having a good metallic com- 
munication with the earth. On one of the Hands there 
was put a pointed wire, the fame as was ufed in the 
fourth experiment; and on the other, a brafs ball of 
three inches diameter. I then placed the point and ball 
each twelve inches from the middle of the bottom of its 
correfpondent hollow cylinder : on charging the artificial 
cloud (which confequently charged the moveable artifi- 
cial cloud in contadt with it) the point was luminous, 
and the moveable artificial cloud Hill remained in an 
horizontal pofition, though there was now a point under 
one end and a ball under the other; and on ceafing to 
charge the two clouds, it was found diredtly after, that 
the point had drawn off almoft all the ele&ric fire from 
both.
