A. Native Gold, Aurum nativum y 



Is in its metallic form commonly pure : 

 And in this (late moil part of this metal uied r 

 in the world is found. With refpect to either 

 the figure or the quantity in which it is found 

 in one place, it is by miners divided into, 



1. Thin fuperricial plated or leaved gold, 

 which confiits of very thin plates or leaves, 

 like paper. 



2. Solid or mafiive, is found in form of thick 

 pieces.

 the quartz in which the gold is found in the Hungarian gold 

 mines is of a peculiar appearance. All other forts of ftones, 

 however, are not to b~ excluded, fince gold is Jikewife found 

 in fome of th.-m ; tor iniUnce, in limeitone (Sett, ix.) in 

 Adolph Frednk's Grufva at Adclfors, in the province of Smo- 

 land; in Hornblende (Sett, lxxxviii.), in Baftnas Grufva at 

 Riddarlhyttan, in the province of Wellmanland ; not to men-

The gr*a.eit quantity of gold is imported into Europe from 

 Ch:H and Peru, in America; and a little from China, and the 

 coafl of Africa. Tne chief European gold mines are thofe of 

 HungLiy, and next to them thofe at Sahzburg'. Befides thefe, 

 there are fome others of lefs confequence ; among which the 

 gold nrnes at Ardfors in Smoland deferve to be take.n much 

 notice of, not only on accoun: of the veins already worked*
