it into one end .of a flick of wax of fix inches in length, 
with eleven pieces of tin-foil ftuck on it at one fortieth 
part of an inch afunder ; then I fcrewed this wax with 
the point on the ftand, and placed it fo that the point 
was direCtly -under the end of the moveable artificial 
cloud, and at eighteen inches diftance as before: on 
charging the artificial cloud, the moveable artificial 
cloud was firft attracted, then repelled, and fo alternately 
as when the ftand with the three inch ball was under; 
but with this difference, that inftead of ftriking in a 
ftrong fpark, as it did to the three inch ball, it now 
ftruck with a very final! fpark to the point, the point 
depriving the moveable cloud of moft of its electricity as 
it approached it, which was very vifibly palling away be- 
tween the reparations of the tin-foil. 
EXPERIMENT XXII., 
Every thing as in the laft experiment,, a chain only 
being hung on the pointed wire, thereby compleating 
the metallic communication with the earth. As foon as 
the chain was hung on, the moveable artificial cloud in- 
ftantly ceafed ftriking to the point, and the other end of 
it was then attracted to the artificial cloud, which then 
kept conftantly ftriking to it: the moveable artificial 
cloud.
