coloured siliceous base at the Hampshire Silver mine (W. R. 
Bell); on lode-matter, mainly Greisen and Quartz Porphyry, 
as a thin powdery crust with Molybdenite, at the Blue Tier; on 
white opaque quartz at the River Iris with the Sulphide and 
Cassiterite. 
144. MESOLITE (Hydrated Silicate of Alumina, Lime, and 
Soda). 
A Zeolite occurring as small globules of a fibrous structure. 
Near railway bridge, Hellyer River. 
145. MIMETITE (Phospho-Arseniate of Lead). 
Occurs in minute bunches of crystals on the wall of a lode at 
the Hampshire Silver mine. The groups of crystals are composed 
of aggregations of six-sided prisms, abruptly terminated at their 
apices, of a highly polished dark brown colour. They are of 
extreme rarity, and were only obtained in one portion of the 
lode. (W. R. Bell). 
146. MIRABILITE—See Grauser Satr. 
147. MARATITE (Sulphide of Zinc and Iron). 
This is apparently a variety of Blende, portion of the Zinc 
being replaced by Iron. It is dark coloured, almost black, with 
a sub-metallic lustre. 
Star of Peace Tin mine, Cascade; Rex’s Hill, near Ben 
Lomond, Mount Bischoff. 
148. MINERAL PITCH—See Aspuattum. 
149. MILOSCHIN (Chrome Ochre). 
A clay-like pulverulent or earthy mineral coloured green by 
Chromic Acid. 
Blue Tier, near Beaconsfield ; Dundas; near Mount Claude. 
150. MENACCANITE (Titanic Iron Oxide). 
This is the “ Black Jack” of the East Coast tin-miners. Itis an 
extremely abundant mineral, its main localities being the Blue Tier ; 
Cascade; Mount Claude; Denison; Dundas; Blythe River 
(blue-black to black); George’s Bay, and other places. The 
variety Nigrine is said to occur abundantly at Rocky Point, 
West Coast; Franklin Harbour. (Ballarat School of Mines 
Museum.) 
151. MONTRONITE (Hydrated Silicate of Iron). 
Always ofa dull greenish colour, with an unctuous feel and 
waxy lustre. Found massive, with a conchoidal fracture. Occurs 
near New Norfolk; Hampshire Hills. (Melbourne Technological 
Museum Collection).
