ELEMENTS OF STATIC ELECTRICITY. 



Now let pail No. 4 be lifted out by the silk cord, and 

 the leaves will converge, and diverge again when it is 

 replaced, showing that the charge on the ball was trans- 

 ferred to it. 



Fig. 12 Combination of Pails. 



Let a connection be now made by pieces of copper 

 wire, let down by silk threads, between each of the 

 pails successively, beginning with 4 and 3, till all four 

 are in electric connection, and let the effect on the 

 leaves be observed as each connection is made. The 

 results will be found the same as in the first experiment,
