ATTRACTION OF GRAVITATION. 



This is undeniably true of the pump suc- 

 tion. All analogy and the limitations of 

 thought, which itself is founded upon the 

 possibilities of experience, force us to the con- 

 clusion that it is true of all kinds of suction 

 and attraction whatever. 



The attraction commonly believed in, as a 

 special form of energy, does not exist ; it is 

 merely a special operation of the energy of 

 repulsion, which is itself only a case of the 

 great law of the conservation of energy or per- 

 sistence of motion, slightly specialised by the 

 transference of the energy or motion from one 

 body to another.
