Cuptauin Bayfield on the 
veins, and disseminated in sienitic granite, asso- 
ciated with purple fluor spar, in Peak Island 
Bay, and near the Black River. Doctor Bigsby 
also found epidote ina quartz vein in granite, 
associated with fluor spar, and, we believe, in 
many other instances. 
ORDER IL—Mica. 
Common Mica.—Occurs, black, white, and brown, as a com- 
ponent part of granite; also in veins. A 
few scales of mica are also visible, occasion- 
ally, in the old sandstone. 
Cutonite.—Occurs disseminated in granite and greenstone. 
chlorite earth occurs also in veins in greenstone 
in the bay next westward of the Peak Island, 
where it is associated with calespar. 
This mineral was also found in veins in granite, 
associated with quartz, felspar, and mica. 
chlorite slate, associated with other slates on 
the south coast of the Slate Islands, 
Green Eantu.—lIt is very plentiful in amygdaloid, in no- 
dules and vesicular cavities, generally asso- 
ciated with calcespar. It very frequently 
coats the agate balls. It isalso disseminated 
through amygdaloid. It is also plentiful in, 
and colours the sandstone occasionally, when 
in the vicinity of the other rocks. 
ORDER IV. 
Maxacaire.—This mineral occurs in a vein about 5 or 6 feet 
wide, in the old red sandstone, on the east 
point of Copperas Harbour, about 7 miies 
westward of the eastern extremity of point 
Keewawonan. 
The direction of the vein is nearly north and 
south, (we did not however take the bearing, ) 
and it is richin ore. Compact blueish green 
malachite
