Two orders of -At the last meeting of the Wernerian Natural History So- 

 veins of miner- ciety, Professor Jameson read a description of contempora- 

 neous or enclosed veins. He divided veins into two classes. 

 The first class comprehends true veins, the second contempora- 

 neous or enclosed veins. 



True veins, he remarked, excepting when the strata or 

 beds are of uncommon thickness, traverse many different 

 strata or beds; and, although we do not always observe them 

 open at the surface of the earth, they invariably open at the 

 surface of the formation or series of formations they traverse ; 

 thus the outgoings or openings of certain metalliferous 

 veins, that traverse clay, slate, and mica slate, are sometimes 

 covered by the second porphyry formation. 



Contemporaneous or enclosed veins are in general con- 

 fined to individual beds or strata, and are completely enclosed 

 in them, or in other words wedge out in every direction in 

 the bed or stratum in which they are contained. After de- 

 tailing the various characters of true and contemporaneous 

 veins, the Professor next described the contemporaneous 



veins
