"NOTES ON THE TWO ELECTRICITIES. 31 



39. But in this last experiment, it is said that the 

 metallic points which project from the conductors A 

 and B withdraw electricity from the atmosphere 

 which is imparted to the machine, and this is indi- 

 cated by a constant succession of sparks that takes 

 place between the balls of the conductors A and B, 

 and those of the machine itself. That this view is 

 also erroneous. I removed from their place the con- 

 ductors with the metallic points, and into the upper 

 part of each of the conductors of the machine I in- 

 serted the extremity of a brass wire, the other ex- 

 tremity of which terminated in a brass ball ; the 

 wires with the balls were made to bend towards 

 each other as is represented in Fig. 6,
