  The 
  numerical 
  values 
  of 
  the 
  functions 
  H, 
  K, 
  L, 
  and 
  M 
  

   vary 
  greatly. 
  H 
  increases 
  rapidly, 
  and 
  K 
  slowly, 
  with 
  rise 
  

   of 
  temperature 
  ; 
  L, 
  M, 
  and 
  N 
  decrease 
  slowly 
  as 
  the 
  

   temperature 
  rises. 
  

  

  Since 
  n 
  observations 
  oan 
  be 
  combined 
  to 
  form 
  - 
  7" 
  

  

  pairs, 
  tliese 
  five 
  determinations 
  yield 
  data 
  for 
  the 
  formation 
  

   of 
  ten 
  cubic 
  equations, 
  of 
  which 
  the 
  values 
  of 
  the 
  coefficients 
  

  

  for 
  five 
  have 
  been 
  calculated. 
  As 
  it 
  IS 
  important 
  to 
  avoid 
  

  

  the 
  introduction 
  of 
  errors 
  due 
  to 
  premature 
  attempts 
  at
