  — 
  Notice 
  of 
  a 
  neic 
  Meteorite. 
  

  

  existed, 
  have 
  been 
  removed 
  bj 
  weathering 
  and 
  the 
  oxidized 
  

   crust 
  appears 
  equally 
  thin 
  on 
  all 
  sides. 
  The 
  fact 
  that 
  the 
  

   edges 
  of 
  the 
  mass 
  are 
  approximately 
  parallel 
  to 
  the 
  lines 
  of 
  

   crystallization 
  is 
  only 
  in 
  accordance 
  with 
  what 
  has 
  been 
  shown 
  

   to 
  be 
  common 
  to 
  siderites 
  in 
  general. 
  

  

  The 
  square 
  fracture 
  is 
  an 
  interesting 
  feature 
  that 
  I 
  believe 
  

   to 
  be 
  quite 
  unusual 
  in 
  iron 
  meteorites. 
  Its 
  surface 
  is 
  nearly 
  a 
  

   parallelogram 
  4:'8x3'3'^"', 
  with 
  one 
  of 
  the 
  shorter 
  sides 
  sur- 
  

   mounted 
  by 
  a 
  triangle 
  3 
  '5*^™ 
  in 
  height 
  ; 
  giving 
  a 
  surface 
  of 
  

   approximately 
  21*5^'' 
  ^°'. 
  One 
  side 
  shows 
  that 
  it 
  has 
  been 
  cut 
  

   by 
  a 
  cold 
  chisel 
  to 
  a 
  depth 
  of 
  about 
  2°"™. 
  The 
  rest 
  of 
  the 
  face 
  

   is 
  a 
  clean 
  straight 
  break 
  with 
  a 
  hackly 
  surface. 
  This 
  is 
  shown 
  

   on 
  the 
  larger 
  mass 
  in 
  -^g^.

  The 
  etched 
  surface 
  presents 
  two 
  main 
  series 
  of 
  lines 
  enclos- 
  

   ing 
  rhombs 
  having 
  the 
  angles 
  161-2 
  and 
  18*8 
  ; 
  other 
  lines 
  

   crossing 
  these 
  produce 
  all 
  the 
  figures 
  compatible 
  with 
  the 
  

   twinning 
  about 
  a 
  cube 
  with 
  the 
  exception 
  of 
  a 
  single 
  line, 
  

   which 
  probably 
  exists 
  but 
  which 
  I 
  have 
  been 
  unable 
  to 
  find. 
  

  

  Under 
  the 
  microscope 
  each 
  higher 
  power 
  up 
  to 
  about 
  one 
  

   hundred 
  diameters 
  reveals 
  lines 
  not 
  seen 
  with 
  lower 
  powers. 
  

   That 
  the 
  series 
  of 
  lines 
  giving 
  the 
  angles 
  above 
  mentioned 
  are 
  

   the 
  primary 
  ones, 
  is 
  indicated 
  by 
  the 
  fact 
  that 
  the 
  lines 
  of 
  frac- 
  

   ture 
  on 
  the 
  broken 
  face 
  have 
  followed 
  these. 
  On 
  a 
  section 
  cut 
  

   at 
  right 
  angles 
  to 
  these^ 
  the 
  lines 
  apparent 
  to 
  the 
  eye 
  give 
  

   decidedly 
  larger 
  figures 
  ; 
  but 
  under 
  the 
  microscope 
  this 
  dis- 
  

   tinction 
  disappears. 
  

  

  The 
  l^eumann 
  lines 
  were 
  visible 
  in 
  the 
  photograph 
  of 
  the 
  

   etched 
  end 
  shown 
  in 
  fig. 
  2 
  ; 
  but 
  are 
  entirely 
  lost 
  by 
  the 
  screen 
  

   used 
  in 
  making 
  the 
  half 
  tone; 
  consequently 
  we 
  introduce 
  a 
  

   print 
  directly 
  from 
  an 
  etched 
  section 
  of 
  the 
  iron, 
  fig. 
  3, 
  which 
  

   under 
  a 
  hand 
  lense 
  should 
  show 
  the 
  lines 
  fairly 
  well. 
  

  

  Troilites 
  appear 
  in 
  all 
  the 
  sections 
  ; 
  but 
  are 
  in 
  most 
  cases 
  of 
  

   very 
  small 
  size. 
  The 
  largest 
  one 
  that 
  appears 
  measures 
  9 
  X 
  13*^'" 
  

   in 
  diameter. 
  It 
  is 
  interesting 
  to 
  note 
  that 
  the 
  Neumann 
  lines 
  

   are 
  materially 
  fiexed 
  immediately 
  about 
  some 
  of 
  the 
  troilites 
  : 
  

   indicating 
  that 
  they 
  existed 
  in 
  a 
  plastic 
  condition 
  during 
  the 
  

   growth 
  of 
  the 
  troilites. 
  

  

  Daubreelite, 
  in 
  unusually 
  large 
  masses, 
  occurs 
  in 
  two 
  of 
  the 
  

   slices 
  ; 
  both 
  as 
  veins 
  crossing 
  the 
  troilites 
  and 
  as 
  solid 
  masses 
  

   at 
  the 
  sides. 
  The 
  largest 
  mass 
  measures, 
  on 
  its 
  two 
  nearly 
  

   rectangular 
  faces, 
  5*5 
  and 
  5"""; 
  the 
  other 
  sides 
  being 
  formed 
  by 
  

   a 
  segment 
  of 
  the 
  nearly 
  circular 
  border 
  of 
  the 
  troilite 
  within 
  

   which 
  it 
  has 
  formed. 
  

  

  An 
  analysis 
  of 
  the 
  iron 
  has 
  not 
  yet 
  been 
  made. 
  

  

  Un 
  fortunately 
  the 
  more 
  euphonious 
  title 
  " 
  Cherokee 
  County" 
  

   has 
  already 
  been 
  applied 
  to 
  the 
  Losttown, 
  Cherokee 
  Co., 
  Ga.. 
  

   siderite, 
  and 
  we 
  are 
  forced 
  to 
  adopt 
  the 
  less 
  pleasing 
  one 
  of 
  the 
  

   town 
  near 
  which 
  it 
  was 
  found, 
  Jlurj)/if/, 
  as 
  the 
  name 
  for 
  this 
  

   meteorite.
