Black Silver-ore. James, p. 177. has been 

 found in the forms just noticed. 

 COPPER ORDER. 



Grey Copper-ore. Kirw. p. 146. F. Veg. ? 



White Copper-ore. Kirw. p. 152. F. Veg. ? 



Vitreous Copper-ore. 



Compact. Kirw. p. 144. F. Veg. This and 

 the two preceding ores are found in the ve- 

 getal form refered to under native silver. 



Copper-Pyrites. Kirw. 140. F. An. and Veg. 

 It is sometimes the matter of testal reliquia,, 

 and frequently constitutes the external parts in 

 petrified fish. Bergman notices copper pyrites 

 in the form of Anomias- The specimens were 

 from Norway, in a matrix of magnet ical iron- 

 ore. 



Malachite. Kirw. p. 131. F. An. and Veg. 



Mountain Green. Kirw. p. 134. F. An. & Veg. 

 Malachite,, mountain green, and,, perhaps, 

 other varieties of what are usually termed cal- 

 ciform copper-ores, sometimes constitute the 

 substance of metallized woods. The most 

 beautiful specimens of this formation are from 



improper to remark, in this place, that all metallic bodies with a 

 seeming organic structure ought to be well studied, previously to 

 their being ranked with extraneous fossils. For, ihe rein is much 

 less frequently the seat of petrifactions than the stratum (v. p. 

 12. r.), and, of course, those ores which occur only in veins, are 

 rarely the constituents of reliquia.
