ing off into black or brown, and are frequently in connexion 
with the red and green tourmaline. 
7. Tabular crystals of this kind are mostly found imbedded 
in mica, and are from one to three inches in length, its 
general appearance being almost a velvet black, except the 
edges, which are translucent, and transmit a pale green light 
bordering on blue. Some specimens of this kind exhibit a 
fine polish, and are extremely handsome. 
8. Rubellite-—~It is mostly found enclosed in crystals of 
the green tourmaline, or clse encrusted with that onits sur- 
face, and varies in its colour from a pink toa deep crimson 
red; some are found very beautiful. 
9. White Tourmaline.—It bas longitudinal strie, and like 
the others becomes electric by friction; most of them are 
slightly tinged with red. a 
10. Lalae coloured Mica.—This is found in small globular 
concretions, consisting of minute folia, placed one upon an- 
ether so as to form short columns, situate mostly parallel 
to each other, and held together by a siliceous cement, in 
which are discovered small crystals of quartz, and occasion- 
ally of the tourmaline. These folia are easily separated from 
each other, and appear to be hexedral tables. 
11. Lilac coloured Mica.—This kind possessing a bright- 
er colour, occurs in more massive forros, and with larger 
folia, and is found in connexion with a beautiful laminated 
feldspar. 
12. Prismatic Mica is found in long capillary threads, on 
the edge of the common mica, resembling much the fila- 
ments of amianthus, and in some instances exhibiting itself 
in the form of long prismatic tables. 
Mica is also found at the same place, crystallized in beau- 
tiful hexedral pyramids. Similar crystals of black mica 
are also found imbedded in white. Large plates of white 
laminated mica are also found here, measuring six inches by 
nine. 
13. This specimen exhibits partially the gangue in which 
the tourmalines are found. 
_ 14. Black Tourmaline.—Specimens of this kind of the 
tourmaline, are found very plenty here in almost every ledge, 
and sometimes very beautiful. They are frequently be- 
tween three and four inches in diameter, and more than one 
foot in length, exhibiting most of the forms mentioned by
