68 _ A List of Minerals and Organic Remains. 
Yellow mica in small spangles is plentifully intermixed 
with the alluvial sand of the valley of the River St. 
Charles near Quebec. i 
It is in plates a foot in diameter in porphyritic granite at 
Cap Tourment; and on the north east shore of Lake Hu- 
rop, 50 miles east of the French River: and at the Grand 
Calumet Portage on the River Ottawa. 
Chlorite Earth—Lake of the woods; Rainy Lake, 
Lakes Superior and Huron. : 
This is a plentiful mineral. In the Lake of the woods 
it is a conformable vein in Greenstone running E. by N. 
dipping northerly. It is from 9 to 12 inches thick——its tex- 
ture is coarse earthy, soft fissile, slightly slaty--and con- 
tains octohedral crystals of iron ore and ‘cubic iron pyrites. 
In Rainy Lake, Lake Superior, and near the Sagamuc 
River in Lake Huron it occurs under similar circumstances. 
it is found in gneiss 3 miles North from the Giants’? Tomb 
in the last named Lake, on a barren islet. 
Green Earti.--Lake Superior. -In Amygdaloid in coat- 
ings, and disseminated. ' i 
Common Serpentine.—Lakes Huron and Simcoe—rol- 
led. At Greenville on the Ottawa, 65 miles north west. 
from Montreal, and at Gananoque 20 miles below Kings- 
ton, U. C. it occurs in large and small irregular masses in 
a calcareous cement—subordinate to gneiss in the latter 
case. J! am not disposed to regard this rock asa breccia. 
Ligneous Ashestus.—North west coast of Lake Huron in 
veins traversing transition Greenstone. — 
Basaltic Hornblende.—Lake Huron—Montreal Moun- 
tain—Banks of theRichelieu near Chambly, L. C. In 
all instances, in a compact trap.—In the rock of Mon- 
treal the terminations project and display the four trape- 
zoidal faces, corresponding to four of the lateral planes, 
as is common in this mineral. 
Common Aciynolite—Crow Lake, 30 miles north of 
Lake Ontario, in the township of Marmora. I have seen 
a fine specimen from this locality, in possession of the late 
Mr. Spilsbury, surgeon in the Royal Navy, Kingston, U. C. 
Glassy Actynolite——York, U.C. In a rolled aggregate 
of petalite, quartz, tremolite, and calc. spar. It is a very 
handsome groupe of crystals, “‘ of a fine green colour, ce- 
mented together by lamellar carbonate of lime. They
