344 On Metallic Minerals. 



Professor Eaton says in No. 1 of the 18th vol. of Silliman's 

 Journal, page 52 : — " If General Field's specimen of gold, 

 found in Newfane, Vermont, was a native specimen, we 

 may anticipate the discovery of gold in the talcose slate, 

 from Georgia to Canada, along the east side of the green 

 mountain range." — (Note 9.) 



Gold is far from heing of rare occurrence ; it is said 

 indeed, that the sand of few rivers is entirely free from it, 

 although the proportion, in almost all cases, is so small as 

 to be undeserving of notice, in a commercial point of view. 



Mica and talc often resemble in colour, external lustre, 

 and flexibility, the native ores of gold and silver. The 

 former earthy mineral is sufficiently distinguished from 

 these, by its elasticity, specific gravity, and want of the 

 true metallic lustre. Talc is distinguished from them by 

 the two last characters. 



Gold, in situ, is almost entirely confined to primary 

 rocks ; it has been observed, however in secondary. But 

 it is among the alluvial deposits that it is more generally 

 found. 



ORES OF ANTIMONY. 



Antimony, as an ore, kas been said to have been fre- 

 quently met with, but I know of no locality. It has been 

 supposed to exist in the neighbourhood of St, Paul's 

 Bay, L. C. 



ORES OF LEAD. 

 tULPHURET OF LEAD. — GALENA. 



Lead, as a sulphuret, has been found in many places, 

 particularly near Lake Memphrcmagog, L. C. where it is 

 said to occur in great abundance. Silver also has been 

 reported to exist in the same place, put there appears to be 

 much greater certainty of the presence of the former than
