306 MINERALOGY. 



Eofmannite.—A colorless, tasteless liydi-ocarbon, found in tabular crys- 

 tals on lignite. Described by Becbi. 



Eunfilite. — 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 C. Doelter 

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

 near Jaulingite, another resin found at the same place. 



Leucomanganite. — A foliated, radJated, snow-white mineral, composed of 

 manganese and iron protoxide*, alkab, and water in unknown pro- 

 portions. Named by Sandberg^sr. 



Lintonite. — An hydrous calcium aluminum sodium silicate, closely allied, 

 perhaps, identical, with thompwouite, 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 by D. 

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

 It is an hydrous lime i)otash silicate. 



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

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

 with a bluish tint ; found in indistinct striated prisms in a black bitu- 

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

 the i^resence of manganese. Described by A. Carnot. 



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

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

 Caiion, Utah. It occurs in colorless fibrous crystals 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 reuiform aggregations, and granular irregular par- 

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



Newberylte. — Another mineral found by vom Rath in the Victoria guano 

 beds ; it is a magnesium ijhosphate 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. 



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

 Smith ill 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).
