 line earths, \vith fuch an cxccfs of earthy matter 

 as nearly to obliterate their faline character, 

 ought thus to be exprcfled.

 means of the trivial names. The celebrat- 

 ed Linnaeus firft made u fc of fuch, in his Spe- 

 cies Plantarum of 1753, by which every fpecies 

 could be conveniently cxprcflcd, without a repe- 

 tition of the fpccific diflcrenccs. The language 

 of botany became thus remarkably cafyand in- 

 telligible ; and zooiigifts and mmcralogifts have 

 to thank the lame author for the happy intro- 

 duclion of them into their fcicnccs. But, al- 

 though thcfe names may be aflumcd from the
