INTllODUCTION. 



This Haudbook has been prepared primarily in the hope that it 

 may be useful to persons visiting the Mining and Greological 

 Museum. It deals principally with the mineralogical collections 

 and ore occurrences ; separate publications, dealing in detail 

 with the rocks and fossils, are in preparation. 



While not containing much that is new, the collections 

 described are so comj)rehensive that this work will perhaps 

 prove of some assistance to students desiring to obtain a know- 

 ledge of the Mineralogy of IS'ew South Wales. 



Explanatory Notes are scattered through the text, but the 

 frequent custom of including a few chapters on Mineralogy and 

 Crystallography has not been followed. This information can be 

 much better obtained from the admirable little text-books that 

 are now everywhere procurable.
