Mr.. nairne’s Experiments to jhew the 
EXPERIMENT XXVIIV 
The three tenth ball being removed, another of one 
inch, and three tenths was tried as in the two laft experi- 
ments, and the ftriking diftance was generally fifteen 
inches. 
But when the weather has been favourable for elec- 
trical experiments, I have feveral times had ftrokes to the 
point from its palling fwiftl'y, and as near as it could 
without touching the ball, till it was brought down to 
one inch and' feven tenths, then the artificial cloud would 
ceafe ftriking to it till it was removed down to three 
inches and five tenths; it would then begin ftriking 
again, and continue ftriking to it all the while it was 
removing to the diftance of ten inches and three tenths. 
And when the three tenth ball was on in the place of 
the point, the artificial cloud would ftrike to it from its 
palling fwiftly, and very near to the ball; and continue 
ftriking all the while it was removing to the diftance of 
two inches and nine tenths; then the artificial cloud 
ceafed ftriking to the ball till it was removed to; three 
inches and feven tenths, and after that diftance con- 
tinued ftriking till it was removed down to ten inches 
and' eight tenths. But when a ball of one inch and three 
tenths
