served distinct, colorless, and transparent crystals in the primary 
form, and measuring more than an inch in length. These crys- 
tals are occasionally replaced on their solid angles and terminal 
edges, so as to produce low pyramidal terminations. This 
thomsonite agrees with that from Dumbarton in Scotland, in its 
, chemical and physical characters. 
The mesotype is in masses of a finely radiated or plumose 
structure, and when broken, presents, in the less compact parts, 
small intersecting fibres of a beautiful silky white appearance. 
Its texture, near the surface, is unusually compact, breaking with 
a splintery fracture ; and some specimens in this respect, as well 
as in point of color, resemble the bones of animals, for which they 
are sometimes mistaken by the inhabitants, who plough them up 
from the soil of their fields. We did not observe in any of these 
specimens, well marked appearances of crystallization. Attached 
to the mesotype and thomsonite, are small masses of foliated 
stilbite and crystals of analcime. Several veins of magnetic iron 
ore occur on this mountain, but they are worthless, in a practical 
view, from their narrowness and inconsiderable extent. 
The next place, which will prove interesting to the mineralo- 
gist, is Peter’s Point. This name is given toa promontory, which, 
projecting into the Bay of Fundy, forms a shelter on the west to 
‘a small creek, into which a stream, sufficiently large to carry a 
saw-mill, called Stronoch’s Brook, discharges its waters. The 
geological features of this place are similar to those at St. Croix 
Cove, excepting that the cylindrical cavities are here wanting, 
and the amygdaloid has been washed away from under the super- 
incumbent columnar rock, which presents an overhanging preci- 
pice, threatening to crush the traveller who may venture beneath
