The  exterior  characters  of  this  anthracite  ar6  somewhat  different  fmi
tho.sc  of  either  of  the  preceding.  The  main  cleats,  or  partingli  *"
marked  by  thin  lamellae  of  white  earthy  matter,  apparently  composd
of  sulphate  of  lime.  These  partings,  however,  are  only  obsetvaUe  il
two  fK>sitions  of  the  specimens,  and  but  little  affect  the  general  color  oj
the  coal,  wliich  is  deep  black,  with  occasional  approaches  to*  blue-UfJci,
in  parts  slightly  tinged  with  oxide  or  sulphuret  of^iron.
