Mount Ramsay, Tasmania. 

 (Plate Ixxviii., fig. 4). 

 This is the mineral analysed by Traube^. It occurs in horn- 

 blendic rock in well formed crystals up to one inch in length and 

 in crystalline bunches. The measured crystal is about 1 cm. in 

 the direction of the vertical axis and is greyish and semi-trans- 

 lucent. The faces are fairly brilliant and gave good signals ; only 

 the pyramid e (101) is present.

VESUVIANITE. 



Barraba, New South Wales. 

 (Plate Ixxviii., figs. 5, G). 



Vesuvianite is found as yellowish-green transparent crystals in 

 and near a cutting on the road from Barraba to Bundarra, slightly 

 eastward of the Ironbarks Creek crossing. It has been described 

 by Mr. D. A. Porter*, who states that it is found lining cavities 

 in massive garnet forming a vein in serpentine. The crystals are 

 accompanied by silica in the form of hyalite, and a greenish 

 mineral in thin tabular, hexagonal crystals which has not yet been 

 determined but may belong to tlie chlorite group. The base is 

 usually present but is invariably rough and non-reflecting. 



One of the best and largest crystals, 3 5 X 1 mm., was measured 

 and yave the following; forms and angles :
