  An 
  examination 
  of 
  the 
  above 
  Table 
  shows 
  (1) 
  that 
  no 
  fewer 
  

   than 
  six 
  triads 
  are 
  formed 
  in 
  the 
  series, 
  in 
  which 
  the 
  sum 
  of 
  

   the 
  atomic 
  weights 
  of 
  the 
  extreme 
  members 
  is 
  double 
  the 
  

   atomic 
  weight 
  of 
  the 
  means, 
  and 
  all 
  are 
  multiples 
  of 
  Ne7. 
  

   Triads 
  of 
  atomic 
  weights 
  have 
  been 
  fully 
  recognized 
  by 
  

   Dumas, 
  Faraday, 
  and 
  other 
  philosophical 
  chemists 
  as 
  in- 
  

   dubitable 
  evidence 
  of 
  community 
  of 
  origin, 
  of 
  transmutation, 
  

   and 
  important 
  factors 
  in 
  the 
  classification 
  of 
  elementary 
  

   substances. 
  (2) 
  That 
  the 
  atomic 
  weight 
  of 
  silicon 
  (35) 
  

   follows 
  naturally 
  in 
  the 
  series, 
  and 
  the 
  lesser 
  values 
  Si 
  21, 
  

   and 
  Si 
  28, 
  find 
  no 
  place 
  in 
  the 
  table. 
  (3) 
  That 
  if 
  the 
  atomic 
  

   weights 
  of 
  Ne 
  ? 
  Ar, 
  Kr, 
  Xe 
  were 
  doubled, 
  it 
  would 
  be 
  

   necessary 
  to 
  double 
  those 
  of 
  N, 
  Si, 
  Fe, 
  Pd, 
  Au, 
  and 
  other 
  

   members 
  of 
  the 
  series, 
  which 
  is 
  obviously 
  absurd. 
  

  

  As 
  the 
  four 
  new 
  elementary 
  gases 
  have 
  no 
  chemical 
  pro- 
  

   perties 
  their 
  specific 
  gravities 
  are 
  necessarily 
  substituted 
  for 
  

   atomic 
  weights. 
  The 
  experimental 
  determinations 
  of 
  their 
  

   respective 
  densities 
  differ 
  slightly 
  from 
  my 
  table 
  owing 
  to 
  

   the 
  difficulty 
  of 
  separation 
  from 
  each 
  other, 
  probably 
  from 
  

   other 
  causes 
  which 
  it 
  is 
  unnecessary 
  on 
  this 
  occasion 
  to 
  

   indicate. 
  In 
  the 
  interests 
  of 
  science, 
  however, 
  it 
  is 
  incum- 
  

   bent 
  on 
  me 
  to 
  say 
  that 
  no 
  teacher 
  of 
  natural 
  science, 
  with 
  

   the 
  above 
  table 
  before 
  him, 
  is 
  at 
  liberty 
  to 
  double 
  the 
  atomic 
  

   weights 
  of 
  the 
  inert 
  gases 
  of 
  the 
  series 
  H 
  In 
  without 
  violence 
  

   to 
  his 
  moral 
  intelligence 
  and 
  lasting 
  injury 
  to 
  the 
  ingenuous 
  

   student 
  who 
  looks 
  up 
  to 
  him 
  for 
  guidance 
  and 
  instruction. 
  

   These 
  remarks 
  are 
  equally 
  applicable 
  to 
  the 
  doubling 
  of 
  the 
  

   atomic 
  weight 
  of 
  helium, 
  which 
  element 
  has 
  been 
  separated 
  

   from 
  the 
  series 
  H2n, 
  and 
  grouped 
  with 
  Ne, 
  Ar, 
  Kr, 
  Xe, 
  

   solely 
  on 
  account 
  of 
  its 
  chemical 
  inertness, 
  the 
  five 
  elements 
  

   having 
  no 
  other 
  rational 
  classification.
