  phism. 
  The 
  determined 
  silicate 
  minerals 
  are 
  olivine 
  and 
  an 
  ortho- 
  

   rhombic 
  pyroxene 
  with 
  small, 
  interstitial 
  areas 
  of 
  a 
  clear, 
  colorless, 
  

   doubly 
  refracting 
  mineral 
  which 
  in 
  a 
  few 
  instances 
  shows 
  plainly 
  

   the 
  twinning 
  striae 
  characteristic 
  of 
  a 
  plagioclase 
  feldspar. 
  The 
  cut 
  

   surface 
  shows 
  numerous 
  black 
  veins, 
  some 
  of 
  which 
  are 
  mere 
  lines, 
  

   but 
  in 
  one 
  instance 
  4 
  — 
  5 
  millimeters 
  in 
  diameter 
  enclosing 
  fragments 
  

   of 
  the 
  silicates, 
  the 
  whole 
  imparting 
  a 
  somewhat 
  breccia 
  structure 
  to 
  

   the 
  stone 
  (see 
  pi. 
  1). 
  

  

  Under 
  the 
  prevailing 
  system 
  it 
  would 
  be 
  classified 
  as 
  a 
  veined 
  

   white 
  chondrite. 
  

  

  This 
  stone, 
  the 
  doubtfully 
  meteoric 
  iron 
  of 
  Oktibbeha 
  and 
  a 
  small 
  

   stone 
  that 
  fell 
  near 
  Palahatchie 
  in 
  Rankin 
  County 
  on 
  October 
  17, 
  

   1910, 
  represent 
  the 
  sole 
  contributions 
  of 
  the 
  State 
  of 
  Mississippi 
  to 
  

   our 
  knowledge 
  of 
  the 
  distribution 
  of 
  these 
  very 
  interesting 
  bodies.
