  two 
  papers 
  interesting 
  to 
  mineralogists, 
  by 
  Wirt 
  Tassin, 
  one 
  a 
  cat- 
  

   alogue 
  of 
  a 
  series 
  of 
  specimens 
  illustrating 
  the 
  various 
  properties 
  

   of 
  minerals; 
  and 
  a 
  second, 
  the 
  detailed 
  system 
  of 
  classification 
  of 
  

   species 
  adopted 
  in 
  the 
  Museum. 
  The 
  remaining 
  papers 
  are 
  upon 
  

   ethnographical 
  subjects; 
  one 
  of 
  these, 
  by 
  J. 
  D. 
  McGuire, 
  describes 
  

   the 
  pipes 
  and 
  smoking 
  customs 
  of 
  the 
  American 
  aborigines; 
  

   another, 
  by 
  Thomas 
  Wilson, 
  describes 
  pre-historic 
  arrow-points, 
  

   spear-heads, 
  and 
  knives. 
  Both 
  of 
  these 
  are 
  fully 
  illustrated 
  and 
  

   will 
  be 
  found 
  interesting 
  by 
  those 
  at 
  work 
  in 
  this 
  department.
