5. Chlorite, loose scaly particles of a dark green colour, 



earthy chlorite of Werner :•'.*•.• 2'706 



6. Chlorite, massive, composed of large granular indivi- 



duals, dark green, from the Rothen Kopf moun- 

 tain in Salzburg 2"713 



7. Chlorite, of the same kind, only the individuals 



smaller 2*729 



8. Chlorite, a similar variety, consisting of still smaller 



individuals 2*731 



9. Chlorite in large lamiuce, and most perfectly cleava- 



ble, more translucent, from the same locality . . - . 2*775 



10. Chlorite, liver brown rhombic prisms, imbedded in 



compact green chlorite, from the same locality. . . 2-781 



1 1 . Chlorite, composition almost impalpable, and fracture 



slaty, of a dark mountain green colour 2*799 



This variety contains minute crystals of rutile. 



12. Green earth, a compact, celandine green variety, 



from Monte Baldo, near Verona 2*834 



On account of the difficulty cf obtaining it free 

 from mechanical admixtures, this specific 

 gravity is, perhaps, not quite exact, 



13. Mica, perfectly cleavable individuals, engaged in 



granite, showing iridescent fissures parallel to the 

 iaminse, colour oil green perpendicular to the axis, 

 more brown parallel to it, from the Schwamberg 



Alps in Stiria 2*883 



It has two axes of double refraction, like the 

 white mica from Siberia. 



14. Mica, perfectly black, in a granular composition, 



exhibiting a tendency to slaty structure, from the 

 district of Pinzgan, in Salzburg 2*911 



15. Mica, silver w^hite crystals, from Zinnwald, Saxony . . 2*945 



16. Mica, greenish black, in large perfectly cleavable 



individuals, Siberia 2*949 



17. Lepidolite, peach blossom red, compound of granular 



individuals, from Rosena, Moravia 2*831 



18. Another specimen of the same 2*833 



19. Pearl mica, perfectly cleavable, reddish white crystals 3*022 



20. Hydrate of magnesia, white laminse, perfectly cleava- 



ble and translucent, from Unst 2*350
