For obvious reasons 1 am not at present allowed to name tlie 

 precise locality. The mineral was subjected to a thorough 

 examination both chemical and physical, and there can be no 

 doubt of its identity. Since it contains about 25 per cent, 

 of nickel it will doubtless prove of considerable commercial 

 value. 



Celestine, Steoxtium sulphate. 

 I have obtained this mineral in the form of small crystalline 

 nodules from a clay deposit near AVallaroo. 



Chalcotrichite. 

 This somewhat unusual form of cuprite has been met with in 

 a specimen from this colony (the exact locality is unknown). 

 The mineral occurs in groups of small acicular crystals with 

 native copper. 



Several other minerals are in course of being examined, and 

 when completed the results will be communicated to this 

 Society, but I regret very much that this interesting work is 

 delayed in consequence of my having so little spare time to 

 devote to the subject. That considerable advantage would 

 accrue to the colony generally by the examination of the 

 various minerals which abound there can be no doubt, and I 

 trust that the time is not far distant when this work will be 

 undertaken, not as at present by one or two persons who have 

 only a few spare hours to devote to the work, but by a compe- 

 tent mineralogical chemist who can devote his whole time and 

 energy to the duty.
