mineral species, and especially of crystalline forms. Indeed 
if a line be drawn from the point where the Catawba enters 
South Carolina, to the north east corner of Stokes county on 
the Virginia line, with a bend to the westward to make it in- 
clude the greater part of Iredell, the part of the state possess- 
ing much interest for the mineralogist will lie on on weiss 
side of this line. On the eastern side of it I am aware 
that a single specimen of s nas common ae as Poi

may exist, especially beyond the formations next to be treat-

there are i rocks earing a resemblance to those

parent connexion with any other. This is a beautiful granite,
