ELECTRIC DISTRIBUTION AND CONDENSATION.

ductor, be insulated and connected by a wire with an 

 electroscope U, and let an electrified metal ball B be 

 lowered into it by a silk cord. The leaves will diverge 

 as the ball enters, and the divergence increase till the 

 ball has passed some distance below ' the edges : after 

 which the divergence is not increased by its further 

 descent.

If it be lifted out without having touched the pail, 

 the leaves will converge, and the ball show no loss of 

 charge : but, if allowed to touch while below the edge,
