  Watson 
  — 
  Meteoric 
  Iron 
  from 
  Paulding 
  County. 
  

  

  The 
  maximum 
  diameters 
  of 
  the 
  fresh 
  portion 
  of 
  the 
  iron 
  are 
  

   6 
  cm 
  by 
  3-7 
  cm 
  by 
  2'2 
  cm 
  (fig. 
  1) 
  ; 
  weight 
  134*3 
  grams. 
  Its 
  general 
  

   outline 
  is 
  irregular 
  and 
  when 
  examined 
  in 
  detail 
  is 
  quite 
  ragged 
  

   in 
  places. 
  The 
  sawn 
  and 
  polished 
  surface 
  exhibits 
  several 
  

   minute 
  fractures 
  with 
  oxidation 
  apparent 
  along 
  most 
  of 
  these. 
  

   In 
  structure 
  the 
  iron 
  is 
  a 
  coarse 
  (broad) 
  octahedrite, 
  the 
  lamellae 
  

   being 
  mostly 
  1*5 
  to 
  2 
  mm 
  in 
  width 
  (fig. 
  2).

  Through 
  the 
  courtesy 
  of 
  Doctor 
  George 
  P. 
  Merrill, 
  the 
  

   writer 
  was 
  afforded 
  opportunity 
  for 
  comparing 
  the 
  Paulding 
  

   County 
  iron 
  with 
  other 
  irons 
  from 
  Georgia 
  and 
  the 
  adjoining 
  

   states 
  in 
  the 
  collections 
  of 
  the 
  IT. 
  S. 
  National 
  Museum. 
  The 
  

   results 
  were 
  uncertain 
  and 
  of 
  slight 
  value, 
  because 
  of 
  the 
  very 
  

   small 
  surface 
  of 
  the 
  available 
  Paulding 
  County 
  iron, 
  but 
  so 
  far 
  

   as 
  could 
  be 
  judged 
  it 
  resembled 
  more 
  closely 
  the 
  Cherokee 
  

   County 
  (Canton), 
  Georgia, 
  iron, 
  and 
  the 
  following 
  two 
  from 
  

   Tennessee 
  : 
  Cleveland 
  (East 
  Tennessee) 
  and 
  Cooperstown, 
  Rob- 
  

   ertson 
  County. 
  In 
  neither 
  case, 
  however, 
  was 
  the 
  resemblance 
  

   close, 
  but 
  only 
  very 
  general, 
  and 
  so 
  far 
  as 
  the 
  comparison 
  has 
  

   value 
  it 
  must 
  be 
  concluded 
  that 
  the 
  Paulding 
  County 
  iron 
  is 
  

   different 
  from 
  any 
  yet 
  found 
  in 
  Georgia 
  and 
  adjoining 
  states 
  

   in 
  the 
  collections 
  of 
  the 
  U. 
  S. 
  National 
  Museum. 
  

  

  It 
  is 
  of 
  interest 
  to 
  note 
  that 
  of 
  the 
  three 
  irons 
  mentioned 
  

   above, 
  which 
  most 
  closely 
  resemble 
  the 
  Paulding 
  County 
  iron, 
  

   Farrington* 
  groups 
  the 
  one 
  from 
  Georgia 
  (Canton, 
  Cherokee 
  

   County) 
  with 
  " 
  coarsest 
  octahedrites 
  " 
  and 
  the 
  two 
  from 
  Ten- 
  

   nessee 
  (Cleveland 
  and 
  Cooperstown) 
  with 
  u 
  medium 
  octahe- 
  

   drites." 
  The 
  analysis 
  of 
  the 
  Canton 
  Georgia 
  iron 
  (coarsest 
  

   octahedrite) 
  is 
  given 
  in 
  column 
  II 
  below 
  for 
  comparison, 
  with 
  

   that 
  of 
  the 
  Paulding 
  County 
  iron. 
  The 
  two 
  irons 
  are 
  quite 
  

   similar 
  in 
  composition.
