xerted upon either atom, when z=1; and n= the constant 
of hi electri attraction, which will also be the constant of the 
equal force of repulsion propagated from the surface of the 
atom through the universal ether. Also Jet u= the force of 
electric repulsion, and v= the excess of the attractive force over 
the ethereal repulsion developed by the attraction; all the forces 
being considered as taking effect upon the central atom, 
effective action ea by either molecule upon the other will 
be the difference between the values of wand v. Denote it by 
JF; then Pibawe When the calculated value of / is positive 
the action will be attractive; when it is negative the action will 
be repulsive. ese have for the force of attraction the general 
expression are ; for the ethereal repulsion the expression
