76 A List of Minerals and Organic Remains. 
Specular Tron Ore.—-At Fort Wellington, U. C. and 
Hawksbury, on the Ottawa, coating granitic bowlders in 
amorphous masses——and on the north east shore of Lake 
Huron imbedded plentifully in granite. It has a purple 
tarnish, and from the quantity [ have -_ with rolled, there- 
abouts, i is most probably in place not 
Meadow Iron Ore.—At Three Rivers and Batiscan strewn 
on the ground in marshes and woods. 
Bog Iron Ore.—-At Batiscan, Three Rivers, Bay of 
St. Paul, Carrying-place of the Bay of Quinte, &c. &c, &e. 
Black and Brown Hematite.—In very small quantities 
lining fissures of transition quartz, at ete Douce in 
Lake George, below the Falls of St. 
Sphene.—At Hawksbury, on the e Orava in a rolled ag- 
lique tetrahedral prisms opaque, chesnut brown, usually 
small, but sometimes ? of an inch long. Recog nized by 
Dr. Hyde Wollaston. 
Foliated Galena.—In large rolled lumps in the alluvion 
or diluvion of Fort Wellington, imbedded in the transition 
quartz of La Cloche, on the north shore oi i Lake Huron, in 
thready veins in the transition greenstone of the north-west 
main of that Lake. It is abundant in the gneiss and gra- 
nite in the rear of Kingston, U. C. occurs sparingly in 
the limestone of the Falls of Sigirns ; but more plentifully 
in- that of the river Ouse of the north shore of Lake Erie. 
Yellow Blende.—In imbedded crystalline masses in the 
shell limestone of the Falls of Montmorenci, in that of 
Montreal, and of the Falls of Niagara; where it is of great 
beauty, aed in nodules, each weighing some ounces. In 
all these three localities it is coated with white quartz. At 
Niagara it occurs in the common er — forms, usually 
small, but rarely, almost as large as a 
To the catalogue of the organic remains occurring in 
Canada, I beg to premise a few summary observations on 
the limestone ' which furnishes them 
heir relation to the subjacent rocks and uniform similari- 
ty in structure and contents, mineral as well as organic, 
seem to indicate that the beds of limestone extending with 
few or no interruptions from Cape Tourment, below Que- 
bec, to near the Falls of St. Mary, are the effects of a con-
