very unsatisfactory group. The Bischoff samples are soft, com- 
pact, and grey in colour; that from the Hampshire is much darker, 
almost black in colour, with the surface shining. 
92. FLUORITE (Fluoride of Calcitum—Fluor-spar). 
Some very fine masses of this mineral have been obtained at 
the Great Republic and other tin mines situated at Ben Lomond. 
The crystals are usually small, but beautifully defined: a common 
form is pale purple to almost colourless, with the apices of the 
acute angles distinctly stained an intensely dark purple. Modi- 
fications of form and macles are not uncommon at this locality. 
Much of the Fluor-spar occurring in this island belongs to the 
variety Chlorophane, which see. 
93. FRANKLINITE (Oxides of Iron, Manganese, and Zinc). 
A mineral with metallic lustre, dark, almost black colour, and 
characteristic reddish-brown streak. Obtained in amorphous 
and crystalline bunches intermixed with galena, mainly at the 
200 feet level, Silver Queen Mine, Zeehan. 
94. GARNET (Silicate of various bases). 
Undetermined species occur at the Hampshire Hills, where 
they are found in profusion. They vary from brown to black in 
colour, and often reach an inch in diameter. On the south side 
of Cape Barren Island they exist in st¢w in a quartz porphyry, also 
freeinthe detritus derived therefrom usually mixed with Cassiterite ; 
at several localities in the north-eastern tin fields they are plentiful 
in the drift, but generally of small size ; common in the vicinity of 
Mt. Heemskirk, usually opaque, but sometimes of good colour 
and transparent; near Mt. Claude a solid compact to sub- 
crystalline garnet rock of yellowish-brown colour occurs 
apparently belonging to the sub-species Grossularite; at Mt. 
Ramsay another rock mass has been found of a dark brown 
colour ; at this locality well formed crystals have been obtained 
imbedded in a soft magma that allows them to be easily extracted ; 
near Highwood, on the Emu River, clearly cut dodecahedrons of 
a translucent white to light yellow colour occur in lode-matter 
(W. R. Bell); on the Whyte River, near the Meredith Range, 
in minute crystals and compact masses of reddish-yellow colour— 
apparently belonging to the variety Essonite—with Actinolite 
and Molybdenite as accessory minerals. 
95. GOSLARITE (Zinc Vitriol). 
Occurs as small stalactitic and investing bunches, which are 
usually much stained with iron. 
Obtained in an adit, intermixed with other sulphates. Blue Tier, 
near Beaconsfield.
