  JAPANESE 
  STIBNITE. 
  

  

  We 
  lately 
  bought 
  a 
  superb 
  group 
  of 
  crystals 
  of 
  Stibnite 
  which 
  we 
  offer 
  at 
  $50.00. 
  

   It 
  measures 
  about 
  9 
  x 
  6 
  x 
  3i, 
  with 
  two 
  score 
  or 
  more 
  of 
  terminated 
  crystals, 
  the 
  

   largest 
  of 
  which 
  is 
  about 
  4-| 
  inches 
  in 
  length. 
  The 
  specimen 
  will 
  lie 
  flat 
  in 
  a 
  

   drawer 
  or 
  stand 
  on 
  edge 
  in 
  an 
  open 
  case. 
  The 
  increasing 
  rarity 
  of 
  fine 
  Japanese 
  

   Stibnites 
  justifies 
  us 
  in 
  giving 
  space 
  to 
  this 
  one 
  specimen.
