306 MINERALOGY. 



Hofmannite. — A colorless, tasteless hydrocarbon, found in tabular crys- 

 tals, on lignite. Described by Bechi. 



Huntilite. — A mineral named by Henry Wurtz after Dr. T. Sterry Hunt. 

 It is a basic silver arsenide, but poorly determined. Found at Silver 

 Islet, Lake Superior. 



Koflacliite. — This is a kind of mineral pitch or resin, found by G. Doelter 

 near Koflach. The author names it with doubt, and says it is very 

 near Jaulingite, another resin ibund at the same place. 



LeucomanganUe. — A foliated, radiated, snow-white mineral, composed of 

 manganese and iron protoxides, alkali, and water in unknown pro- 

 portions. Named by Sandbergwr. 



Lintonite. — An hj^drous calcium aluminum sodium silicate, closely allied, 

 perhaps, identical, with thompaonite, which was found in amygda- 

 loidal cavities in diabase near Grand Marias, Cook County, Minnesota. 

 Named after Miss Laura Linton, the analyst of the specimens. 



Louisite. — A leek-green translucent vitreous brittle mineral found Ijy D. 

 Honeymau, at Blomidon, Nova Scotia, and named from the princess, 

 It is an hydrous lime potash silicate. 



Luckite. — An hydrous manganese iron sulphate, found with mallardite 

 in the Luckyboy silver mine, Butterfield Canon, Utah. It is clear, 

 with a bluish tint ; found in indistinct striated j)risms in a black bitu- 

 minous rock, isomorphous with melanterite, from which it differs in 

 the presence of manganese. Described by A. Carnot. 



MaUardite. — An hydrous manganese sulphate, soluble in water, de- 

 scribed by A. Carnot, from the Luckyboy silver mine, Butterfield 

 Canon, Utah. It occurs in colorless fibrous cr^^stals in a gray clay 

 like stone, together with quartz and barite. 



Mixite. — A copper bismuth arsenate containing water. It is found as 

 an emerald or bluish-green incrustation on bismuth ochre. It forms 

 spherical and reniform aggregations, and granular irregular i^ar- 

 ticles. Found in the Joachimsthal, and determined by A. Schrauf. 



Newberyife. — Another mineral found by vom Eath in the Victoria guano 

 beds ; it is a magnesium i^hosphate containing water, and orthorhom- 

 bic in crystallization. 



Ontariolite. — An '' embryonic" mineral, named before its investigation by 

 Prof. C. U. Shepard. It is a member of the scapolite family, found at 

 Ottawa, Canada. 



Orizite. — A mineral of the composition of heulandite found in the tour- 

 maline granite at San Piero in Campo, by Grattarola. It occurs in 

 crystals, and crystalline grains of the color and luster of rice kernels. 



Peclihaniite. — A magnesium iron silicate found by Dr. J. Lawrence 

 Smith in the meteorite that fell in Emmet County, Iowa. It is dingy- 

 yellow in color, has a perfect cleavage, and occurs in nodules several 

 millimeters in diameter. It is intermediate between olivine and bron- 

 zite. Named after Professor Peckham, who first described the fall of 

 this remarkable meteorite (see Meteorites).
