120 ONTOLOGY. 



Every one will easily see that these groups of metals 

 agree with their antetypes in properties, as also that this 

 arrangement is more natural than any that has hitherto 

 been advanced. Glancing at it, it must strike the reader 

 that in several of the families 4 metals are present, and 

 that none exceed this number. There are 4 sideroid, 4 

 titanoid, 4 platinoid, 4 arsenicoid and 4 argyroid metals. 

 Now, as they are to be viewed as deoxydized earths, 

 it must be assumed that in each family they are mindful 

 of their origin, and everywhere represent the 4 earths 

 along with the character of their family. They are earths 

 divided unto the last members, or reduced in a primo- 

 chemical manner. In order to recognize the parallelism 

 of the classes, orders and families, we have only to com- 

 pare the adjoining table. We cannot expect to find all 

 the minerals ranging there in their proper place. For we 

 are treating the subject at present only as regards its 

 principles.
