848 Mr. nairne’s Experiments to Jfcew the 
part with it filently, by means of the point, without 
ftriking on it till the charged cloud is nearly exhaufted. 
When we fee a cloud ftriking into another cloud feve- 
ral times together, we conclude from all the known law's 
of eledlricity, that the cloud which firft received the 
ftroke mu ft have difcharged part or the whole of what 
it received before it could receive another ftroke. 
In the twentieth experiment we find, that though our 
moveable artificial cloud was in great motion, receiving 
and difcharging its electric fire on the ball, that, on 
taking away the ball, and putting the point in its place, 
the artificial ftorm immediately ceafed. 
In the twenty-firft experiment, where the point was 
on a ftick of wax, with reparations in the metallic com- 
munication with the earth, we find that, even in that 
fituation, the ftroke on the point was very fmall to what 
it was on the ball with a good communication, great part 
of the ele6tric fire vifibly palling off as the cloud ap- 
proached the point; and when the metallic communica- 
tion was made compleat by hanging on the chain, it then 
ceafed ftriking to the point.
