  None 
  of 
  the 
  rarer 
  elements 
  sometimes 
  reported 
  as 
  occurring 
  in 
  

   meteorites 
  were 
  found, 
  although 
  very 
  carefully 
  looked 
  for. 
  

  

  Should 
  we 
  refer 
  all 
  the 
  soda 
  and 
  lime 
  to 
  the 
  feldspar 
  it 
  is 
  evident 
  

   that 
  it 
  belongs 
  to 
  an 
  acid 
  type 
  nearer 
  albite 
  than 
  oligoclase. 
  That 
  

   all 
  the 
  lime 
  can 
  not 
  be 
  so 
  referred 
  is, 
  however, 
  rendered 
  doubtful 
  by 
  

   the 
  following: 
  

  

  An 
  attempt 
  was 
  made 
  to 
  isolate 
  some 
  of 
  the 
  component 
  nunerals 
  

   by 
  the 
  usual 
  process 
  of 
  crushing, 
  washing, 
  and 
  use 
  of 
  heavy 
  solution. 
  

   The 
  results 
  were 
  complete 
  failures. 
  In 
  the 
  course 
  of 
  the 
  attempt, 
  

   however, 
  the 
  water, 
  in 
  which 
  a 
  finely 
  pulverized 
  sample 
  had 
  been 
  

   standing 
  for 
  some 
  24 
  hours, 
  was 
  tested 
  and 
  gave 
  distinct 
  reactions 
  

   for 
  lime 
  and 
  sulphuric 
  acid. 
  Three 
  independent 
  tests, 
  two 
  by 
  myself 
  

   and 
  one 
  by 
  ]\ir. 
  Chester 
  GUbert, 
  yielded 
  similar 
  results, 
  Mr. 
  Gilbert 
  

   getting 
  0.0052 
  grams 
  of 
  CaO 
  from 
  9.2495 
  grams 
  of 
  the 
  pulverized 
  

   stone 
  after 
  digesting 
  in 
  distilled 
  water 
  for 
  24 
  hours. 
  Mr. 
  Andrew 
  A. 
  

   Blair, 
  at 
  my 
  request, 
  digested 
  a 
  powdered 
  sample 
  for 
  24 
  hours 
  in 
  

   dilute 
  hydrochloric 
  acid, 
  1 
  part 
  acid 
  to 
  50 
  parts 
  water. 
  The 
  solution 
  

   yielded 
  0.28 
  per 
  cent 
  CaO, 
  0.05 
  per 
  cent 
  SO3, 
  and 
  1.14 
  per 
  cent 
  MgO, 
  

   the 
  last 
  named 
  undoubtedly 
  derived 
  from 
  the 
  oli^ane. 
  These 
  results 
  

   led 
  to 
  a 
  very 
  careful 
  search 
  for 
  oldhamite, 
  the 
  rare 
  calcium 
  sulphide. 
  

   With 
  one 
  possible 
  exception 
  nothuig 
  could 
  be 
  found 
  in 
  the 
  slides 
  

   that 
  could 
  with 
  any 
  degree 
  of 
  certainty 
  be 
  thus 
  referred, 
  and 
  one 
  is 
  

   forced 
  to 
  conclude 
  that 
  if 
  such 
  existed 
  it 
  has 
  gone 
  over 
  to 
  an 
  earthy 
  

   or 
  perhaps 
  ocherous 
  gypsum 
  and 
  is 
  no 
  longer 
  recognizable. 
  It 
  will 
  

   perhaps 
  be 
  remembered 
  that 
  I 
  was 
  driven 
  to 
  a 
  similar 
  conclusion 
  in 
  

   the 
  case 
  of 
  the 
  Hamblen 
  (Morristown), 
  Tennessee, 
  sideroHte, 
  de- 
  

   scribed 
  some 
  years 
  ago.* 
  It 
  is 
  of 
  course 
  possible 
  that 
  the 
  minute 
  

   quantity 
  of 
  lime 
  found 
  may 
  have 
  come 
  from 
  an 
  easily 
  decomposed 
  

   feldspar.
