independent of the constants P & P, . 



Hence, the attractive or repulsive force pre- 

 dominates according as the distance between the 

 particles is greater or less than two . 



The force which is required to disengage rigidity 

 will be a little greater than P.IOOO' + P,.100 . 



From what has preceded, respecting molecular 

 forces and their mode of action, namely, by 

 attraction and repulsion simultaneously, so that 

 the material mass is entirely influenced and 

 governed by the difference of these molecular 

 forces, we shall be enabled to suggest, for future 

 consideration, a new theory of aggregation and 

 stability of material bodies, that will explain a 

 great number of natural phenomena which have 

 not been hitherto successfully explained by any 

 of the theories proposed for that purpose.
