Augite ? probably enters into the composition of some of the 
traps, but itis not easy to distinguish it from horn- 
blende. 
Coccolite—Disseminated through magnetic iron, in rear of St. 
Paul’s Bay. 
Garnet (common)—Forming distinct nodules in micaceous 
schist at Mal-Bay ; the beautiful foliated variety 
of precious garnet, known to occur here, was not 
seen. 
Magnetic Iron—In extensive beds in rear of St. Paul’s Bay. 
Also forming veins and small distinct concretions in 
the syenites, and disseminated in small grains 
through some of the traps of the country we tra- 
versed. 
Green Carbonate of Copper ?—In small traces among some 
of the syenites we met with. 
It must be obvious to those instructed on the subject, that an 
individual rapidly traversing a country, will acquire a know- 
ledge of its geognostical features more readily than he can hope 
to obtain of its mineralogy, because rocks, unlike minerals, 
occupy large spaces, and a specimen struck from one place is 
characterestic of many others ; but minerals, with the excep- 
tion of those which enter among the constituents of rocks, are 
very partially deposited, and either chance favors the hasty 
tourist, or they must be very abundant in the places he seeks 
them, if many be met with. 
Passing Cap Pillard, near St. Joachim, Mr. Nixon ob- 
served a vein of a green afd white substance from three to 
six inches in thickness traversing the rock. Upon landing, 
specimens were procured which being examined subsequently, 
were found to be mixtures of carbonate of lime, under the form 
of calcareous spar, aod a variety of fluate of lime, denominated 
chlorophane,
