wound up in, or joined clofe to it. The peculiar 

 filver- veins rich in glajfy, red and white goldijh ores 

 remarkably differ from the abovementioned coarfe 

 fort, as the pyrites generally keeps at adiflance from 

 thefe, nay is feldom found in the felvages. But I 

 would not be here underftood of veins, where 

 fome of the above noble ores are either inter- 

 fperfed in fiflures, or weathered on drufe*, or lay 

 fprinkled on the firm mixt-work; mod of which 

 will be found to confift of galena, copper -ore, py- 

 rites, mock-lead, mifspickel. The fame remarks 

 will hold good of other coarfe veins. 



I have obferved the pyrites-kidneys, as they are 

 called, to be of different fizes, fome equal to 

 mufket-balls, granado's, and others even as large 

 as cannon-balls, tho' oblong, and of a flatted 

 round, rather than quite fpherical ; and generally 

 give no tokens of being mixed with copper, 

 whether examined by the eye or tried by the fire, 

 yet there are fome as thofe of Frankenberg of a 

 flat- round, like the fhell of a tortoife, that at times 

 internally manifefl fome copper-ore, mocklead and 

 mifspickel, which the external appearance of fuch 

 clofe bodies would give no fufpicion of And tho' 

 the pyritte difappear in glitter fiock works, as thole 

 of Hartz •, neverthelefs they are again found when 

 the large flock or belly, formed here by the ore, 

 and called ftock-WGrk, comes to contract again -, as 

 it doubtlefs muft, tho' it runs, as is well known, 

 to feveral fmall firings, difficult, if not impoflible, 

 to be traced.
