  Their

  based 
  upon 
  corrected 
  methods 
  of

  analysis, 
  

   Adam's 
  for

  This 
  was 
  simplified 
  to 
  a 
  formula 
  which, 
  for 
  average 
  milks, 
  was 
  

   said 
  to 
  give 
  results

  within 
  about 
  .02

  the 
  louger

  from

  deduces 
  for 
  a 
  working 
  formula,

  which 
  "

  He 
  gives 
  for 
  a 
  simple 
  working 
  formula, 
  from 
  which 
  results 
  nearly 
  

  

  as 
  accurate 
  as 
  obtained 
  from 
  pre(!eding 
  can 
  be 
  obtained 
  when 
  

  

  milk 
  contains 
  not
