Metallic- Ores. Metals. 

 (Pure or reduced metals.) 



544. The classification of metals is one of the most 

 difficult, because no natural arrangement of them has 

 been as yet attempted, and their signification is also so 

 mysterious that we can only get at it, by clinging fast to 

 the laws of development. Thus assuming, that they 

 likewise arrange themselves according to the elements, 

 classes and orders of the earths, we have at once the Ele- 

 mental metals. The earth-metals are without doubt the 

 difficultly fusible, ignoble or oxydized, such as iron with its 

 congeners. Then the air-metals present themselves with 

 their peculiar character of volatility, as Arsenic with its 

 congeners. These being once rendered solid, the easily 

 fusible but n on- volatile will correspond to water, such as 

 Lead with its congeners. The noble metals consequently 

 as Gold, Silver, &c., must doubtless be regarded as 

 fire-metals. Having once separated these 4 groups, the 

 Class-metals admit of being more readily brought into 

 their place. There is one metal, which subjected to 

 moisture is readily converted into a salt, namely copper. 

 This is consequently the representative of the salts among 

 the metals. Ore-metals are, without doubt, those re- 

 sembling iron, which do not, however, occur in an 

 oxydized condition and are therefore noble Irons. Of this
