7^ ARRANGEMENT OF CHEMICAL PRINCIPLES, 



subject, to consider the earths as elementary 

 principles. 



Oxygene is the vital air of life, the principle 

 of combustion, and the vehicle of heat, — the 

 pure air of Kirwan. 



Hydrogene is the basis of inflammable air, 

 and is the lightest of all ponderable things, — the 

 inflammable air of Kirwan. 



Nitrogene or azote is the opposite of oxy- 

 gene, and is incapable of supporting combustion, 

 and animal life. 



Carbon is the basis of common charcoal, 

 divested of all its impurities. 



Atmospheric air is compounded of the two 

 different permanent substances, oxygene and 

 nitrogene, combining and uniting in certain 

 proportions, and rendered aerial by the expansive 

 power of heat or caloric. 



Water is formed by the two permanent sub- 

 stances, oxygene and hydrogene, combining or 

 uniting in certain proportions, and which, in its 

 common state, always holds a certain portion of 

 earth in a state of solution, and generally of 

 carbon also. 



As these elementary substances are in them- 

 selves indestructible, and, combined in different 

 proportions, form the whole of both animals and 

 vegetables, it clearly appears that animal and
