Special and as complete series as possible of the 

 local fossils. 



A series showing the different ores from which 

 each of the metals are obtained, accompanied by maps 

 and other graphic representations to show the pro- 

 portion of the metal in each ore, the localities at 

 which each of the ores is mined, etc. 



Series illustrating the various steps in the mining 

 and metallurgy of the different metals, with speci- 

 mens, as far as possible, illustrating the appearance 

 of the ore at different stages, the other materials used 

 in the process, and the by-products and waste, and 

 with charts and photographs exhibiting the remaining 

 phases of the process. 



Similar series for building stones and fuels. 



A collection of gems, showing the gem in the 

 rough and when cut, and also the appearance of the 

 same mineral in its more massive form; models of 

 the crystalline form, etc. 



It is hoped that the second edition of this Guide 

 will be more than a prospectus for this department.
