Hepfernan's Lease, Torrin'gton, New South Wales. 



(Plate xxxviii.) 



Here we have a large Japan twin in a group of untwinned 

 crystals of quartz. It has the characteristic flattened form. 

 Towards the bottom of tlie figure can be seen the impression of a 

 crystal of beryl with prismatic striations, beryl being associated 

 with quartz at this mine'^. 



WULFENITE. 



Junction Mine, Broken Hill, New South Waleb. 



Plate xxxix., figs. 1,2.) 



At this mine wulfenite occurs in small crystals, light red in 

 colour, of about 3 cm. in diameter. Two somewhat different 

 habits are recognisable as shown in the . figures. Forms present 

 are :— c (001), m (110), g (310), k (210), e (101), n (111). The 

 prisms are not well developed, in being very narrow while 

 k and q are very much rounded. When both n and e are present 

 e is the larger and is dull with drusy appearance ; n is bright and 

 gives a good reflection. In every case there is apparently a 

 horizontal plane of symmetry. 



Leigh Creek, South Australia. 



At this locality small brown crystals of wulfenite are associated 

 with galena. The crystals are very simple, n (111) being the only 

 form px-esent 



MONAZITE. 



King's Bluff, Olary, South Australia. 



(Plate xxxix., figs. 3-7.) 



Monazite was found in October, 1906, in small veins and 

 vughs in the quartzite at the King's Bluff gold mine"*. It has 

 also been obtained in the alluvial gold deposits of the same dis- 

 trict. The Trustees recently acquired a collection of the crystal- 

 lised monazite from Mr. Charles Bogenrieder, Mining Engineer. 

 The crystals are about 5 cm. in greatest diameter, and of a
