CHAPTER VIII. 



The Evolution of Gases and Liquids. 



Having learnt the materialistic alphabet, discovered 

 the fundamental basis of existence, determined the 

 fundamental substance of phenomena, established the 

 fundamental agencies of evolution, and detailed the 

 fundamental and efficient laws of energy which govern 

 the earth, if not the universe, we now proceed to trace, 

 link by link, that sequence of phenomena by natural 

 causes which indubitably demonstrates the material- 

 istic character of all evolution. Beginning with the 

 least in production, gases and liquids, we shall gradu- 

 ally rise through minerals, vegetals and animals, until 

 we reach the highest product of organised matter on 

 earth, the most wonderful and enigmatical to man of 

 all natural automata — man himself. 



Although gases and liquids have many interesting 

 problems, they need not detain us. It is only neces- 

 sary to mention some of the more salient facts that 

 affect our system. 



Jn gases, the atoms are in what may be called a.
