called mineral acids, the fluoric and boracic acids, the 

 first of which, as conqueress of the earths is the earth 

 acid, the last being thus the acid of the salts. We have 

 accordingly 



a. Elemental acids. 



1. The oxydized aether is Carbonic acid. 



2. The oxydized air Nitric acid. 



3. The oxydized water Hydro-chloric acid. 



b. Mineral acids. 



4. The oxydized earth is Fluoric acid. 



5. The oxydized salt Boracic acid. 



6. The oxydized inflammable Sulphuric acid. 



7. The oxydized metal Arsenic acid. 



512. The vegetable and animal acids are none other 

 than repetitions of the elemental and mineral acids. They 

 may perhaps be parallelized in the following manner. 



Fire-acid (Carbonic acid) Acetic acid Hsematosine. 



Air-acid (Nitric acid) Malic acid Lactic acid. 



Water-acid (Hydro-chloric acid) Saccharine acid Mucic acid 



Earth-acid (Fluoric acid) Tartaric acid Phosphoric ac. 



Salt-acid ( Boracic acid) Tannic acid Uric acid. 



Inflammable-acid (Sulphuric acid) Succinic acid Sebacic acid. 



Ore-acid (Arsenic acid) Indie acid Formic acid. 



All the remaining acids must be viewed as subordi- 

 nate to, or as kinds of these. 



513. The alkalies appear to follow the same course, 

 though it does not admit of being so completely demon- 

 strated. 



Fire-alkali Ammonia Vegetable, and Animal alkalies. 



Air-alkali Potash Alcaloids Alcaloids. 



Water Soda Urea. 



Earth Lithium Bile, &c. 



Salt 



Inflammable 



Ore-alkali 



514. The earths proper do not consist of two prin- 

 ciples, and do not, therefore admit of being chemically 

 divided. 



515. This division is only incorrect in a naturo-histo- 

 rical sense, because it has no reference to the totality. 

 Inasmuch as every mineral class is viewed as having ori- 

 ginated out of only one or two elements, it divides by 

 the chemical method only into constituent parts or frac-
