BROMEL has given no generic chara(5ler. 



The Lapis violaceiis, (Fo denominated from the BiiTiis Julithuf 

 which grows upon it) he has confidertd as a proper fpecies. 



He feparates Sand from Earths. 



Sulphur, order 3, he dillinguifhes from Pyrites, order 10. 



Serpentine, by himfclf and fome others is referred to the Mar- 

 bles. . 



Mica he thinks fit to join with calcareous flones. 



He divides flmple ftones, into thofe which remain unaltered hy 

 theadlionof fiie, thcjie which vitrify by the adion of fire, and thole 

 which by the adiion of fire are reduced to calx. This divifion is 

 fomctimes followed by oihers; by Linne in the orders 3, 2, i. 

 by Wolttrfdorf in the orders 2, 4, i. by Walleriiis in the orders 

 3, 2, I. by Anonymus in the orders 4, 2, i. and by Vogel in the 

 orders 1, 5, 2. 



The Bromelian method can hardly be called a fyftem, in as much 

 as he has omitted the clafiification, generic chara£ler, fpecific dif- 

 ferences, and the fynonyms of Authors.
