N. B. Eighty of thofe parts make one inch. 
The number oppolite the word electrometer denotes the diflance between the 
balls which confiituted the electrometer ; and the numbers oppofte to the words 
ball and point fhew the ultimate diftance at which they were refpeCtively {truck. 
(b) The point and ball in this experiment were not directed immediately 
towards the outiide coating of the jar, but towards the broad furface of a com- 
mon tea cannifceiy the oppofite outfide of which was in contact with the coating 
of the jar.
