Arr. VI.—Geology of a portion of the Labrador 
Coast, by Lieut. Baddeley, Royal Engineers. 
Verx little is known of either the geology or mineralogy 
of any portion of the coast of Labrador, and for that little we 
are almost entirely indebted to the Rev. Mr. Steinhaeur, ex- 
tracts from whose communication on the subject to the Geo- 
logical Society of London, will be found at tne end of this 
article. 
In the autumn of 1827, Capt. Campbell, h. p. 79th Regi- 
ment, visited the coast of Labrador, from Bradore to Cha- 
teau Bay, and bronght back with him the necessary materials 
for affording the following report, which he kindly placed at 
my disposal. 
On the island of Quirpon, about one hundred yards to the 
north of Newfoundland, quartz rock was observed, forming 
a thick continuous vein or stratum running north east. It is 
remarkably pure, white, compact and deeply translucent on 
the edges. A tendency to the formation of regular crystals 
appears in some hollows and nests in the mass. 
These crystals when near the external surface of the rock, 
are often characterized by having beautifully polished faces, 
as if they had been operated upon by the lapidary’s wheel ; 
the same is also observod of some portions of the surface, 
which exhibit no tendency to regular crystallization. Dr. 
MacCulloch has noticed the same fact in his paper on Quartz 
Rock, page 480, vol. 2, of the Geological ‘Transactions, 
At Cape Charl.s, onthe Labrador coast, immediately op- 
posite, the same rock was observed, and vader similar cir- 
cumstances. 
At Francis harbour, on the Labrador coast, an aggregate 
‘composed of quartz and calcareous spar, forms a continuous 
scaly
