NATURAL HISTORY. 
new residence at Canonteign; found on 
the North-East range of the sienite of 
Bottor Rock, in the stones quarried for 
that building. The late Revd. J. Hill, of

Bottor Rocks also. The fracture of this 
sienitic rock often exposes a vitreous

Crystallized. 
Black—splendid specimens of this mineral 
accompanied by large crystals of apatite, 
occurred in a bunch, with clay, quartz 
crystals, and carbonate of iron, some

sing granite, at Wooley, in the parish of 
Bovey Tracey ; a new cut that has lately 
been made in the Turnpike road, between 
that and Moreton, passes thro’ the spot,

micaceous iron; we believe the cavity has 
been exhausted, some specimens that have

six or more sides, variously terminated.

Calcureous Spar—crystals of a great variety of 
forms are frequent on the sides and crevices 
of the lime rocks, quarries &c. and well 
defined ones are also frequent in the red
