  861st 
  meeting 
  

  

  The 
  861st 
  meeting 
  was 
  held 
  at 
  the 
  Cosmos 
  Club 
  auditorium, 
  February 
  11, 
  

   1922, 
  with 
  President 
  Crittenden 
  in 
  the 
  chair 
  and 
  40 
  persons 
  present. 
  The 
  

   following 
  program 
  was 
  given: 
  

  

  Edward 
  Wichers: 
  The 
  purification 
  of 
  certain 
  elements 
  in 
  the 
  platinum 
  

   group. 
  

  

  (Author's 
  abstract.) 
  The 
  need 
  for 
  public 
  information 
  on 
  the 
  elements 
  of 
  

   the 
  platinum 
  group 
  led 
  the 
  Bureau 
  of 
  Standards 
  to 
  conduct 
  an 
  investigation 
  

   of 
  the 
  properties 
  of 
  these 
  elements 
  and 
  their 
  alloys. 
  The 
  precision 
  required 
  

   in 
  the 
  determination 
  of 
  physical 
  properties 
  made 
  it 
  necessary 
  to 
  prepare 
  each 
  

   of 
  the 
  elements 
  in 
  a 
  state 
  of 
  highest 
  possible 
  purity. 
  These 
  very 
  pure 
  metals 
  

   will 
  also 
  be 
  used 
  as 
  material 
  for 
  the 
  study 
  of 
  analytical 
  methods 
  for 
  the 
  plati- 
  

   num 
  group.
