To this lift late difcoveries have added four new 

 femimetals, viz. Uranite, Sylvanite, Titanite, and Me- 

 nachanite. But of their nature little is known: and it 

 is with fome hefitation that I infert their names in the 

 vocabulary of fimple elements. 



In the prefent ftate of natural knowledge, however, 

 moft of the above may be confidered as diftincl: ele- 

 mentary fubftances, fmce they are found to be un- 

 changeable or unconvertible into other fubftances, 

 though they may be, and generally are, combined with 

 Others. This fact, v/as it not for the advantage of 

 claflification, would therefore oblige us to admit in na- 

 ture, inftead of eleven, at leaft forty diftind, fimple, 

 and elementary fubftances.
