RECORDS OF THE AUSTRALIAN MUSEUM. 



These also are penetrated by limonite stalactites, mostly powdery, and 

 are elongated parallel to the vertical axis. There are only a few forms 

 present, namely c (001), a (100), m (100), '? (102), of which the two last 

 are the best developed (PI. xxxix., fig. 4<).

A specimen lent by Mr. Arthur Combe consists of anglesite in small 

 crystals, the largest about 5 mm. in diameter, accompanied by limonite 

 and small spherules with a pearly lustre which dissolve in hot hydro- 

 chloric acid with effervescence, giving a yellow solution containing much 

 iron ; these spherules are apparently siderite or ferruginous calcite. 

 Anglesite has not previously been recorded from this lode, the outcrops of 

 which consist of ferruginous and siliceous gossan, with native silver, 

 chloride of silver, azurite, malachite, cerussite, and other minerals, 

 passing downwards into sulphides of iron, copper, lead, and zinc.-^ 



The crystals of anglesite are fairly constant in habit, the largest 

 faces belonging to c (001), m (110), d (102), o (Oil).
