 RECENTLY DETERMINED, WITH NEW LO- 

 CALITIES FOR SPECIES KNOWN TO OCCUR 

 IN TASMANIA.

The present contribution to the mineralogy of this State 

 is of somewhat unusual interest, inasmuch as it describes 

 for the first time an apparently new compound, which, 

 although of no commercial value, is of some scientific 

 interest. It is in its way a humble congener of the more 

 imposing crocoisite, for the occurrence of which, in such 

 magnificent developments, this island has obtained a great 

 repute among mineralogists in all parts of the world, but, 

 like it, is simply of scientific importance. 



The Lefroy meteorite, now mentioned for the first time, 

 is, although of such remarkably small size, worthy of 

 special note, and its detection in the prospector's dish adds 

 another to the romantic discoveries of such objects from 

 unknown space. The already long list of the different 

 minerals recorded from time to time as being found in this 

 State is still further augmented by the addition of no less 

 than eighteen not heretofore published ; respecting these 

 concise notes are given. Several of these are of some 

 scientific interest, and twj or three would be of industrial 

 importance if they could be discovered in sufficient 

 quantity. Notes on additional localities for a few others 

 which are already on record are given, w^th some remarks 

 on peculiar features presented by some few others. 



I have to record my obligation to Mr. J. D. Millen, 

 A.S.T.C, M.S.C.I., Lond., metallurgical chemist, for so 

 generously undertaking the analysis of Bellite and Her- 

 cynite, for without this work, especially difficult as regards 

 the first mentioned, my task would have lost its most 

 important features. 



1 Barrandite.^ — {Hydroys aluminium and iron phos- 



phate.) 

 Occurs as brown dull amorphous masses of small 

 size, associated with vivianite, Lyndhurst, North- 

 East Coast. 



2 Bellite. — {Chromo-arsenate of lead.) 



This extremely interesting and, it may be said, 

 attractive new substance usually occurs in delicate 

 tufts aggregated together, and velvet-like coated 

 surfaces thickly lining and clustering in drusy
