  Amongst 
  the 
  conclusions 
  to 
  be 
  drawn 
  from 
  the 
  facts 
  that 
  

   have 
  been 
  mentioned 
  is 
  this, 
  that 
  the 
  color 
  of 
  the 
  elementary 
  

   atoms 
  is 
  to 
  a 
  large 
  extent 
  a/ 
  'unction 
  of 
  their 
  atomic 
  weights. 
  

   We 
  find 
  that 
  with 
  atomic 
  weights, 
  

  

  From 
  1 
  to 
  47 
  the 
  atoms 
  are 
  always 
  colorless 
  

   From 
  52 
  to 
  59 
  they 
  are 
  always 
  colored 
  

   From 
  65 
  to 
  90 
  they 
  are 
  always 
  colorless 
  

   From 
  103 
  to 
  106 
  they 
  are 
  always 
  colored 
  

   From 
  112 
  to 
  139 
  they 
  are 
  always 
  colorless 
  

   From 
  145 
  to 
  169 
  they 
  are 
  always 
  colored 
  

   From 
  192 
  to 
  196 
  they 
  are 
  always 
  colored. 
  

  

  Elements 
  whose 
  place 
  in 
  the 
  numerical 
  series 
  falls 
  between 
  

   these 
  periods, 
  have 
  both 
  colored 
  and 
  colorless 
  atoms. 
  

  

  The 
  six 
  metals 
  that 
  remain 
  are 
  as 
  we 
  have 
  seen, 
  alternately 
  

   colored 
  and 
  colorless. 
  

  

  Ostwald 
  remarks 
  in 
  his 
  great 
  Lehrbuch 
  that 
  when 
  the 
  prop- 
  

   erties 
  of 
  the 
  elements 
  shall 
  show 
  themselves 
  to 
  be 
  functions 
  of 
  

   their 
  atomic 
  weights, 
  we 
  have 
  next 
  to 
  seek 
  in 
  the 
  latter 
  the 
  

   cause 
  of 
  the 
  former, 
  and 
  then 
  we 
  shall 
  hardly 
  be 
  able 
  to 
  avoid 
  

   the 
  conception 
  of 
  a 
  single 
  primordial 
  form 
  of 
  matter 
  as 
  sug- 
  

   gested 
  by 
  Crookes, 
  a 
  form 
  whose 
  varied 
  modes 
  of 
  agglomera- 
  

   tion 
  condition 
  the 
  various 
  kinds 
  of 
  matter 
  (Yol. 
  I, 
  p. 
  138). 
  

  

  Perhaps 
  the 
  facts 
  in 
  this 
  paper 
  described 
  may 
  be 
  found 
  to 
  

   make 
  a 
  step 
  towards 
  this 
  great 
  end. 
  

  

  With 
  the 
  aid 
  of 
  the 
  Arrhenius 
  theory 
  it 
  has 
  been 
  possible 
  to 
  

   establish 
  the 
  principle 
  that 
  the 
  colors 
  of 
  the 
  atoms 
  are 
  those 
  

   which 
  they 
  show 
  in 
  dilute 
  solutions 
  of 
  electrolytes, 
  and 
  that 
  

   the 
  colors 
  of 
  elements 
  are 
  comparatively 
  of 
  little 
  importance. 
  

   In 
  the 
  second 
  part 
  of 
  this 
  paper 
  there 
  will 
  be 
  given 
  incident- 
  

   ally 
  a 
  proof 
  of 
  the 
  correctness 
  of 
  the 
  dissociation 
  theory 
  from 
  

   a 
  new 
  direction. 
  In 
  that 
  part 
  will 
  be 
  considered 
  the 
  combina- 
  

   tions 
  of 
  atoms 
  and 
  two 
  laws 
  controlling 
  in 
  certain 
  cases 
  the 
  

   interaction 
  of 
  ions.
