  — 
  N'ote 
  on 
  a 
  New 
  Meteoric 
  Iron. 
  

  

  indicating 
  it 
  to 
  be 
  schreibersite. 
  The 
  iron 
  is 
  soft 
  and 
  takes 
  

   a 
  high 
  polish. 
  Treating 
  polished 
  surfaces 
  witli 
  dilute 
  nitric 
  

   acid 
  develops 
  an 
  etching 
  barely 
  visible 
  to 
  the 
  unaided 
  eye. 
  

   This 
  consists 
  of 
  innumerable 
  and 
  very 
  minute 
  pits 
  in 
  the 
  

   plessite, 
  with 
  long 
  very 
  line 
  bright 
  lines 
  crossing 
  at 
  right 
  angles 
  

   and 
  occasionally 
  short 
  diagonal 
  lines. 
  

  

  The 
  composition, 
  determined 
  by 
  Mr. 
  J. 
  Edward 
  Whitfield 
  

   from 
  a 
  sample 
  of 
  the 
  iron, 
  only 
  partially 
  freed 
  from 
  schreiber- 
  

   site, 
  is 
  as 
  follows 
  : 
  

  

  Iron

  Several 
  siderites 
  found 
  in 
  Texas 
  bear 
  such 
  a 
  close 
  geograph- 
  

   ical 
  relationship 
  to 
  this 
  one, 
  as 
  to 
  demand 
  comparison. 
  These 
  

   are 
  : 
  Carlton, 
  found 
  in 
  1888 
  about 
  12 
  miles 
  to 
  the 
  southwest 
  in 
  

   Hamilton 
  Co., 
  with 
  12*77 
  per 
  cent 
  nickel 
  ; 
  the 
  Ked 
  River, 
  

   found 
  in 
  1836 
  in 
  the 
  adjacent 
  county 
  (Johnson), 
  with 
  8*46 
  per 
  

   cent 
  nickel 
  ; 
  and 
  Denton 
  Co., 
  found 
  in 
  1859 
  about 
  100 
  miles 
  

   north, 
  with 
  7*53 
  per 
  cent 
  nickel. 
  However 
  the 
  most 
  marked 
  

   variations 
  from 
  the 
  present 
  find 
  are 
  the 
  large 
  and 
  distinct 
  

   Widmannstatten 
  figures 
  which 
  appear 
  on 
  etching 
  the 
  neighbor- 
  

   ing 
  irons. 
  Iredell 
  may, 
  therefore, 
  be 
  safely 
  accepted 
  as 
  a 
  dis- 
  

   tinct 
  fall.
