  6th. 
  The 
  present 
  siderite, 
  Lids 
  Lopez, 
  6*9 
  kilograms, 
  found 
  

   in 
  1896, 
  live 
  miles 
  S.W. 
  of 
  Socorro. 
  

  

  It 
  is 
  absolutely 
  certain 
  that 
  these 
  six 
  finds 
  represent 
  six 
  dis- 
  

   tinct 
  falls 
  of 
  meteorites, 
  as 
  proved 
  first 
  by 
  the 
  analyses 
  :

  Secondly, 
  the 
  crystalline 
  structure, 
  as 
  shown 
  by 
  the 
  Wid- 
  

   manstatten 
  figures, 
  is 
  so 
  entirely 
  different 
  that 
  it 
  would 
  be 
  

   impossible 
  to 
  confound 
  either 
  one 
  with 
  any 
  other 
  of 
  these 
  

   finds.

  The 
  history 
  of 
  this 
  most 
  interesting 
  siderite 
  as 
  to 
  the 
  exact 
  

   date 
  when 
  found, 
  and 
  the 
  precise 
  locality 
  where 
  found, 
  has 
  

   been 
  entirely 
  lost. 
  

  

  The 
  weight 
  of 
  the 
  whole 
  was 
  probably 
  about 
  25 
  kilograms. 
  

   An 
  end 
  piece 
  apparently 
  about 
  half 
  the 
  entire 
  mass, 
  weighing 
  

   12,360 
  grams, 
  has 
  been 
  deposited 
  for 
  many 
  years 
  in 
  the 
  Western 
  

   Reserve 
  Historical 
  Society 
  of 
  Cleveland, 
  Ohio, 
  while 
  the 
  other 
  

   half 
  was 
  in 
  the 
  collection 
  of 
  the 
  late 
  Prof. 
  Win. 
  Denton 
  of 
  

   Wellesley, 
  Mass. 
  Through 
  the 
  Librarian 
  of 
  the 
  Western 
  

   Reserve 
  Historical 
  Society, 
  Prof. 
  J. 
  P. 
  MacLean, 
  Prof. 
  Ward 
  

   has 
  obtained 
  a 
  large 
  portion 
  of 
  this 
  piece. 
  

  

  The 
  outer 
  surface 
  of 
  the 
  mass 
  is 
  most 
  beautifully 
  and 
  typi- 
  

   cally 
  pitted, 
  and 
  of 
  a 
  dark 
  reddish-brown 
  color, 
  with 
  the 
  

   exception 
  of 
  the 
  prominent 
  ridges, 
  which 
  are 
  of 
  a 
  lustrous 
  

   dark 
  steel-gray 
  color, 
  resembling 
  graphite, 
  although 
  it 
  does 
  not 
  

   soil 
  paper 
  when 
  rubbed 
  over 
  it. 
  

  

  On 
  cutting 
  the 
  mass, 
  we 
  found 
  numerous 
  fissures 
  meander- 
  

   ing 
  in 
  various 
  directions 
  over 
  the 
  entire 
  surface. 
  A 
  few 
  of 
  

   the 
  largest 
  are 
  one 
  millimeter 
  in 
  diameter, 
  and 
  are 
  filled 
  in 
  

   part 
  by 
  a 
  black 
  graphite-like 
  substance, 
  and 
  in 
  part 
  by 
  schreib- 
  

   ersite. 
  There 
  are 
  also 
  patches 
  of 
  schreibersite, 
  resembling 
  

   hieroglyphics, 
  some 
  of 
  them 
  5 
  by 
  25 
  mm 
  in 
  diameter, 
  scattered 
  

   here 
  and 
  there 
  over 
  the 
  surface. 
  A 
  few 
  prominent 
  troilite 
  

   nodules 
  are 
  visible 
  on 
  the 
  sections, 
  the 
  largest 
  being 
  9xl5 
  mm 
  

   in 
  diameter. 
  On 
  etching 
  the 
  iron 
  no 
  figures 
  whatever 
  are 
  

   brought 
  out, 
  leaving 
  only 
  a 
  minutely 
  pitted 
  light 
  gray 
  surface, 
  

   which 
  is 
  more 
  or 
  less 
  clouded.

  of 
  the 
  finding

  this 
  siderite
