BROMEL has given no generic charaQer. 
The Lapis violaceus, (fo denominated froni the Bifltis Jolithu? 
which grows upon it) he has confidered as a proper fpecks. 
He feparates Sand from Earths. 
Sulphur, order 3, he diflinguiflies from Pyrites, order 10. 
Serpentine, by himfelf and fome others is referred to the Mar- 
bles. 
Mica he thinks fit to j in with calcareous ftone^ 
' He divides fimple Hones, into thofe which remain unaltered by 
the ad ion of fire, thofe which vitrify by the adion of fire, and thofe 
which by the adion of fire are reduced to calx. This divifion is 
fometimcs flowed by others; by Linne in the orders 3, 2, i. 
by \Volterfdorf in the orders 2, 4, i. by Wallerius in the orders 
3, 2, I. by Anonjmus in the orders 4, 2, i. and by Vogel in the 
orders i, 5, 2.

as he has omitted the claifification, generic charader, fpecific dif- 
ferences, and the fynonyms of Authors.
