Calcite—Dunedin. 
In brown transparent crystals, made up of similar forms to the last. 
Lustre vitreous. Associated with the calcite are radiate groups of natrolite 
crystals, and both are seated upon a pale blue-coloured film of a minutely 
crystallized zeolite, which has some of the characters of gismondine. 
Calcite.—Dunedin. 
In group of translucent pale green-coloured crystals, lining an amyg- 
daloidal cavity. 
Calcite.—Dunedin. 
À group of brown imperfectly-developed crystals. 
Calcite.—Dunedin. 
In radiate groups of small crystals, composed of the scalenohedron and 
rhombohedron combined ; well developed, although almost microscopic in 
size. 
Translucent ; lustre vitreous; in amygdaloidal cavity. There is also 
present in the specimen a cast or impression of a radiate group of acicular 
arragonite crystals. 
Calcite.—Dunedin. 
A group of clear, transparent, and colourless crystals, with vitreous 
lustre. The forms are flattened elongated rhombohedra, which penetrate 
right across the cavity and abut against the opposite side. 
Calcite.—Dunedin. 
A radiated group of crystals consisting of the scalenohedron and 
rhombohedron combined. . 
Arragonite.*—Dunedin. 
Filling amygdaloidal cavities in basalt. 
Arragonite.—Caversham. 
Long blade-like prisms in an amygdaloidal cavity lined with the zeolite 
natrolite. 
Arragonite.—Dunedin. 
In radiate rhombic prisms of a pale pink colour, with vitreous lustre. 
The cavity is lined with small rhombohedral crystals of pale yellow calcite. 
Arragonite.—Dunedin. 
Beautiful rosettes of pale yellow-coloured prisms with vitreous lustre. 
The under portions are much charged with iron, and in consequence 
present a brown colour. Presented by Captain Fraser. 
Selenite.t—Moeraki. 
A clear and transparent form of gypsum, (ie, hydrous calcium sul- 
phate—Ca 80,, 2H,0) ; roughly crystallized ; valuable for the preparation 
of various cements.
