I RETURN  you  many  thanks  for  the  fight  of  the 
ftones  from  the  Cape  of  Good  Hope.  I have  not  time  to 
examine  them  very  minutely ; but  they  feem  to  be  both 
of  the  fame  nature,  granites,  the  fmaller  piece  being 
only  of  a finer  texture.  The  higlieft  points  of  the  Alps 
are  compofed  of  granite  of  the  fame  nature,  and  feem  to 
have  been  lifted  up  by  exhalations,  volcanic  explofions, 
or  fome  fuch  caufes.  This  Angular  immenfe  fragment 
of  granite  moft  probably  has  been  raifed  in  the  fame 
manner.  Moft  of  the  mountains  which  are  called  primi - 
five  (which  I believe  is  only  a term)  are  of  this  texture. 
I am,  See. 
W.  HAMILTON.
