which with masses of wolfram are found in a matrix of clay at 

 Heffernan's Lease. The specimens were donated by Mr. Charles 

 Bogerwieder, mining engineer, from whom particulars of the 

 occurrence were obtained. Individual crystals measure up to 

 6 cm. in horizontal diameter by 5 cm. vertically ; the prisms are 

 striated vertically and invariably broken across. The crystals 

 are very simple, usually showing only the base and a hexagonal 

 prism with an occasional face of a second prism.

(Plate xvi., figs. 4-8.) 



Here beryl occurs embedded in, or associated with, quartz ; 

 the habit is long prismatic; terminated simply by c(0001); 

 colour pale bluish-green. Broken crystals measure up to 

 5-5 x 2 cm. 



ANGLESITE. 



Broken Hill, New South Wales. 



(Plate xiv.; Plate xv., fig. 1 ; Plate xvi, fig. 3.) 



Mr.P. T.Hammond 2 in 1895 figured some crystals of anglesite 

 from the Consols Mine ; in the present paper anglesite from the 

 Central, Block 14, and Proprietary Mines are described. From 

 the Central nine crystals were measured, and two each from Block 

 14 and the Proprietary ; for any one mine the habit is fairly 

 constant and the combinations similar. 



(1) From the Central come as a rule small crystals of about 2 to 

 3 mm. in diameter, which are seated on reticulated cerussite ; 

 sometimes the latter projects as long slender prisms or thin 

 plates amongst the anglesite, and, now and then, a minute, 

 perfectly formed anglesite crystal is poised on the tip of a 

 slender rod of cerussite. The crystals are transparent and 

 colourless to opaque white, or sometimes have a slight yellowish 

 tinge. 



Thirteen forms were determined, of which three are new ; in 

 addition is doubtfully present, and approximate measurements 

 were obtained of what are most likely vicinal faces not deserving 

 of crystallographic symbols. The new forms r(187), X(34T2), 

 and v (598) give by no means satisfactory measurements, as the 

 faces are either small or wavy and the signals distorted, hence the
