 After reviewing the history 

 and geology of this important 

 copper district, the paper gives 

 the results of a detailed metal- 

 lographic study of the ores. 

 The deposition is indicated to 

 have occurred during a distinct 

 mineralizing epoch marked by 

 solutions progressively changing 

 in composition and depositing a 

 series of sulphide minerals in 

 sequential and transitional 

 stages. The article closes with 

 a brief description of analogous 

 deposits and a selected biblio- 

 graphy.

 A new definition for a mineral 

 species is proposed which takes 

 into account variations in com- 

 position due to adsorption and 

 solid solution, and a new term, 

 meta-coUoid, is suggested for 

 colloid minerals which have be- 

 come crystalline, the reasons for 

 these recommendations being 

 discussed at length. Based 

 lai'gely on a study of Museum 

 material.

Discussion of a paper by 



A. F. Rogers, recommending the 



use of mineral species names as 



group names when isomorphism 



is recognized, and the use of 



chemical prefixes to designate 



the end members of isomor-

a study of Museum material.
