PHCENICITE. 



BB like common Mica ; fuses to a white 

 enamel. 



Localities. Found in limestone. Alt- 

 Kemnitz, near Hirschberg, in Prussian Sile- 

 sia, with Garnet and Idocrase. The Vosges 

 Mountains. Sala, in Sweden. Edwards 

 and Rossie, New York, St. Lawrence co., 

 and other places in the United States. 



Name. From <p><.oyco^og (of a fiery appear- 

 ance), on account of its colour. 



Brit. Mus., Case 32. 



Phcenicite, or Phcenikochroite, 

 Glocker. See Melanochkoite. 



Pholerite. a hydrated silicate of 

 alumina, resembling Kaolin in composition. 

 Colour pure white. Formed of small convex 

 scales of a pearly lustre. Soft to the touch. 

 Friable between the fingers. Plunged in 

 water gives out air-bubbles and adheres to 

 the tongue ; produces a doughy mass. S.G. 

 2-35 to 2-57.

BB infusible. 



Insoluble in nitric acid. 



Localities. — English. Coalbrook Dale : 

 of frequent occurrence in crevices of Iron- 

 stone nodules, especially in the Penney- 

 stone band ; in the casts of plants in Iron- 

 stone, &c. — Foreign. France : Fins, Dept. of 

 Allier ; and Hive de Gier, Dept. of the Loire, 

 in crevices in nodules of Coal-measure 

 Ironstone. Belgium; Cache- Apres and 

 Mons. Naxos, Avith Emery. Schemnitz, 

 with Diaspore. From the circumstance of 

 its forming white spots or specks on various 

 rocks, it is called by the workmen " terrain 

 fleuri." It is found abundantly, but not in 

 large pieces, often associated with lamellar 

 carbonate of lime. The coal-mines of 

 Schuylkill co., Pennsylvania, U.S.

Phosphocerite, ^. IVatts. Forms about 

 one-thousandth part of the cobalt ore of 

 Johannisberg, in Sweden. It remains as a 

 residual product, in the form of a greyish- 

 yellow crystalline powder, mixed with a 

 few minute dark-purple crystals, which are 

 strongly attracted by the magnet, and ap- 

 parently consist of Magnetic Iron Ore and 

 oxide of cobalt. The crystals of Phospho- 

 cerite are an octahedron and a four-sided 

 prism, with quadrilateral terminations. Co- 

 lourless, or of a pale sulphur-yellow. Lus- 

 tre adamantine. H. 5 to 5-3. S.G. 4-78. 



Comp. (Ce, La, D)^ P, or identical in 

 composition (though not in crystalline form) 

 with Cryptolite.

Protoxides of cerium, lan- 

 thanum, and didymium . 64*68 

 Oxide of copper . . .2*83 

 Oxide of cobalt, silica, &c. . 3-41 

 Phosphoric acid . . . 28-46

 BB vitrifies partially at the edges and 

 surface, and colours the flame slightly 

 green. 



Phosphochalcite ; Phosphorochal- 

 ciTE, V. Kohell. Rhombic. Occurs crystal- 

 lized in extremely minute individuals, and 

 in fibrous and earthy masses. Colour eme- 

 rald- or verdigris-green, often externally 

 blackish - green at the surface, and dull. 

 Lustre vitreous or adamantine. Translu- 

 cent generally at the edges only. Streak 

 slightly paler than the colour. Brittle. Frac- 

 ture small-conchoidal to uneven. H. 5. 

 S.G. 4 to 4-4.
