of a part of the Saguenay Country, &c. 161 
blance of the hornblende to mica, which latter circumstance 
may indeed have occasioned one mineral to have been mistaken 
for the other. We cannot positively assert that the granite of 
Cape Tourment is free from hornblende, but we think so. 
Micaceous schist was met with only at Mal-bay, where it 
has been already described as dipping to the west, having black 
fetid limestone above it, and qnartz rock and syenitic gneiss be- 
low. It is here that the three classes of rocks (admitting the 
transition to be one) are seen together, and the geologist de- 
rives from their inspection assistance in his subsequent resear- 
ches in the neighbourhood, Micaceous schist being in all cases 
a primary rock, the syenitic gneiss below it, must also be pri- 
mary, which it appears necessary to establish, because the 
same rock was not found elsewhere, to be associated with a 
similar proof of its superior antiquity; rocks in which horn- 
blende and felspar abound, being common to the “ over, 
lyin class’? of Macculloch, with which many of the rocks in 
the Saguenay and elsewhere, have other points of agreement 
besides mere mineralogical identity. 
The syenites and traps are the only rocks met with from the 
mouth of the Saguenay to the falls on La Belle Rivitre, and 
they are likewise most characteristic of the north shore of the 
St. Lawrence, from T'adousac toCape Tourment. Mr. Nixon 
met with syenite on David’s River, a branch of the Perebonea, 
and with trap at the fallsof Ouitchouan, A _ pale syenite is 
the predominating rock in rear of St. Paul’s Bay; with this no 
trap is associated, and it is the deposite of extensive beds of 
magnetic iron, all of which is in favor of its primary character ; 
it possesses no traces of stratification. 
Quartz rock was seen only at Mal-bay, underlying mica- 
ceous schist, aod between it and syenitic gneiss, 
Primary limestone ? associated with syenite gneiss and trap, 
occurs at Moulin’ Baudee A loose mass of a similar descrip-
