(Plate lxxx., fig. 3.) 



This occurrence of azurite has been known for many years, 6 

 but its crystallography has not been investigated, A specimen, 

 probably from the Paisley Mine, was recently secured by exchange 

 with the Geological Survey of Queensland ; it consists of numerous 

 good crystals measuring up to about 5 x 1*5 x 1 cm. accompanied 

 by small crystals of cerussite on a matrix of limonite. The 

 crystals are constant in" habit ; elongated parallel to the b 

 axis, a (100), m (110) and 6 (T01) having the largest faces, The 

 dome faces are striated parallel to their edges. Five crystals 

 were measured. Combinations are tabulated below.
