MINERALOGY. 



MINERALS in their ftriaeft fignification 

 denote only fuch fabftances as are found in 

 mines, fuch as Metals, Semi- metals, Sulphur 

 and Salts; but in a more extenfive fenfe, 

 they denote all foffils that do not belong 

 either to the vegetable or animal kingdoms, 

 and confequently Stones and Earths, all of 

 which are comprehended under the Denomi- 

 nation of the Mineral kingdom. 



The mineral kingdom is therefore ufually 

 divided into four parts or clafles, y/z. 

 I. Earths^ and Stones. II. Salts. III. Inflam- 

 mable Subftances. IV. Metallic Subflances: 

 which naturally point out a fimilar fourfold 

 divifion of this treatife.
