CHEMISTRY. 



s 



making in the methods of analyzing bodies, or 

 separating them into their component principles 

 or elements, several other substances once supposed 

 to be simple are now found to be compounds : and, 

 as chemistry continues to advance, the list of simple 

 substances may be reduced ; our inability to de- 

 compose any body not proving it to be simple, but 

 only, perhaps, that our methods of examination are 

 still imperfect. 



The substances which hitherto have resisted all 

 the known methods of analysis, and which, in the 

 present state oi' our knowledge, are considered as 

 the elements of all bodies with which we are ac- 

 quainted, are the following : —
