XVI. On the Mutual Attraction or Repulsion between two Elec- 

 trified Spherical Conductors. By Prof. W. Thomson*. 



[Continued from vol. v. p. 297.] 



THE following numerical results have been calculated (by 

 means of the formulae established above) for application 

 to the theory of a new electrometer which I have recently had 

 constructed to determine electrical potentials in absolute measure, 

 from the repulsions of uninsulated balls in the interior of a hol- 

 low insulated and electrified conductor, by means of a bifilar or 

 torsion-balance bearing a vertical shaft which passes through a 

 small aperture to the outside of the conductor. 



Table I. — Showing the Quantities of Electricity on two equal 

 spherical conductors, of radius r, and the mutual force between 

 them, when charged to potentials u and v respectively.
