Some New Localities for Minerals in Victoria. 145 



covered with a thin, crystalline, transparent, zeolitic crust 

 (undetermined), but not either of those already found. On 

 this occur calc spar and dog-tooth spar in orange-brown 

 crystals, and often on them again have been deposited the 

 phacolite and phillipsite, which also line the upper portions 

 of the cavities. Sometimes the zeolites occur perfectly 

 crystallised on the ends of thin needles of calc spar, a fresh 

 cavity looking as if the needles held glittering drops of dew 

 in suspension. The zeolites often occur together in the same 

 cavity, and seem to have been deposited simultaneously. 

 Peculiar lumps, generally loaded with fine crystals, occur in 

 many cavities. As these lumps are part of the basalt mass, 

 they have probably been formed by pressure on the cavities 

 during the cooling of the molten basalt." The zeolites appear 

 to be more numerous where water has percolated through 

 the basalt. The water contained in the cavities is highly 

 charged with mineral matter. Only a small quantity 

 has yet been obtained for examination. This gave a 

 residue on evaporation equal to 1 per cent., consist- 

 ing of chlorides of calcium, sodium, and aluminum, with 

 silica and ammonia, and may be looked on as the mother 

 liquor from the crystalisation of the zeolites. Another 

 zeolite, stilbite, has recently been found, for the first time in 

 Victoria, as a crystalline vein in the mesozoic sandstone near 

 Ceres Bridge, Barrabool Hills. Bindhiemite — hydrous anti- 

 moniate of lead — is another mineral new to us ; has been 

 found with the steinmanite from the Murindal lead mines. 

 Mr. Rule has reported the occurrence of both these minerals. 

 Pyrolusite, new to Victoria, is found as the cementing 

 medium of a brecciated quartz conglomerate in the ranges, 

 some fifteen miles from Moe, Gippsland. The crystals are 

 small, , almost microscopic. Tungstite, also new, occurring 

 with wolfram and scheelite, is reported by Mr. Rule from a 

 reef in a hill near the cemetery, Mai don. Scorodite. — Some 

 interesting occurrences of this arseniate of iron have been 

 found at Bethanga and Dry Creek, Strathbogie Ranges. 

 They are both auriferous. The Bethanga specimens are 

 massive and earthy, and of ^concretionary formation. The 

 Strathbogie scorodite is in thin veins in a large auriferous 

 dyke, these veins being evidently the result of the decom- 

 position of arsenical pyrites in situ.
