HOFFMAN ON THE MINERALOGY OF NEVADA. 737 



lodyrite. In minute cubes, coating quartz and argentite, from Eeese 

 Elver District ; sparingly at San Antonio ; White Pine. 



Jamesonite. Humboldt County. (Dana.) 



Jasper. See Silica. 



Kalinite. Massive and columnar, sometimes crystallized, at Mount 

 Diablo. Specimens frequently contain small quantities of sulphur, 

 through liquid infiltration. 



Kennesite. Was reported from Eureka, which is undoubtedly an error. 

 It was found very sparingly in Blind Spring District, California, just 

 across the line from Columbus, during the earlier stage of develop- 

 ment of the mines. 



Kiistelite. Is an auriferous silver, of a silver-white color, somewhat 

 darker than native silver on a fresh surface. Contains silver, lead, 

 and gold, the first much predominating. From the Ophir Mine, 

 according to Dana.* Occurs in bean-shaped grains. 



Lead {Arsenate of). See Mimetiie. 



Lead {Carbonate of). Siee Cerussite. 



Lead {MoJyhdate of). See Wulfenite. 



Lead {Phosphate of ). See Pyroniorphite. 



Lead {Sulphate of). See Anglesite. 



Lead {Sulphuret of). See Galenite. 



Limonite. Lone Mountain. Is also found in many of the silver-mines. 



Magnetite. In considerable quantities in Eailroad District; also at 

 Morey. 



Malachite. Massive ; incrustations and mammillary concretions in Cop- 

 per Caiion, Galena District. Sparingly at San Antonio, Montezuma, 

 and Belmont 5 more abundant at Mineral Hill. 



Manganite. In small crystals, filling cavities in the limestone at Morey 

 Mines. 



Massicot. Galena. (Loew.) 



Menaccanite. In propylite at and near Carlin ; Eureka ; Morey ; Bel- 

 mont. 



Mica {Common). See Muscovite. 



Mica {Brown). See Fhlogopite. 



Mimetite. Sparingly at Eureka. 



Minium. Specimens exhibited to me as from Eureka were undoubtedly 

 obtained, originally, at Blind Spring District (Eockingham Mine), 

 California. Attempts at deception are frequently made for the pur- 

 pose of making sales of specimens from so-called new localities. 

 Found at Pioche. (Loew.) 



Mispiclcel. At Morey, very rarely. 



Moss agate. See Silica. 



Muscovite. Found in small pieces at Carlin and Tuscarora. In fine 

 laminse at Silver Peak ; at Eureka, Morey, and at Belmont in rhyolite. 

 Also in the Black Caiion on the Colorado Eiver.
