opening for mica were seen colonies of crystals of hornblende, 
which presented a very curious appearance. ~ 
‘*Curved Crystals of Hornblende.—In a single colony of horn- 
blende crystals obtained on the dump of this vein of mica, in 
which pink calcite magnetite biotite crystals and hornblende 
crystals were observed, there were no less than fifty crystals pre- 
senting the unusual phenomenon of being curved or bent. That 
some extraneous force or other dynamic agency was at work to 
deform the crystals, is evident from the face of the crystals them- 
selves. There are two phases of the flexure and curved condition 
of these crystals which may be readily observed, viz., (a) the 
broken and re-cemented prisms along one side or plane of the 
crystal ; (4) the uniformly curved and deflected crystal. That the 
dynamic forces at work were strong enough to break many of the 
crystals in the colony is a fact merely to be observed; whilst many 
of the crystals having such a gentle, even and unbroken curve in 
their present appearance would lead me to believe that the crystal 
had once been in a more or less plastic condition. The crystals 
are worth studying more closely. The presence of a pink calcite 
in the mass leads me to infer that the pyroxene crystals were 
probably developed in a vein of this calcium carbonate. In a 
quartz vein said to be gold-bearing and occurring on the ridge, 
which was opened and followed a short distance in the hope of 
finding more material of an auriferous character, fine examples of 
felspar were obtained, which gave evidence of the presence of 
microcline or perthite. They are highly crystalline, exhibiting 
large faces with perfect cleavage everywhere on the dump. 
Crystalline limestone and wollastonite were also observed—the 
limestone holding numerous and irregularly shredded masses of 
rusty gneiss-like structure imbedded throughout their surface out- 
crop which appeared in relief. 
‘On the farm of Mr. James Wilson a sandpit occurs, from 
which the members of the Geological Section obtained a fine series 
of marine shells, referable to two species only : Macoma fragilis, 
Fab.( =. Balthica, L.) and Saxticava rugosa, L.”’ 
The entomologists of the party, although few in number, 
made some acceptable captures, and doubtless would have col- 
lected many more interesting insects, had the day been more suit-
