  A 
  limestone 
  to 
  be 
  used 
  in 
  sugar 
  manufacture 
  must 
  not 
  have 
  

   more 
  than 
  25$ 
  alkalies. 
  

  

  The 
  following 
  are 
  analyses 
  of 
  limes 
  used 
  by 
  German 
  beet 
  sugar 
  

   manufactures.

  It 
  will 
  be 
  noticed 
  from 
  the 
  above 
  analyses 
  that 
  in 
  most 
  of 
  the 
  

   samples 
  the 
  percentage 
  of 
  lime 
  is 
  over 
  90$ 
  though 
  in 
  some 
  it 
  is 
  

   under 
  80,$. 
  Another 
  noticeable 
  feature 
  is 
  the 
  low 
  percentage 
  of 
  

   both 
  magnesia 
  and 
  alkalies, 
  specially 
  the 
  latter. 
  One 
  shows 
  the 
  

   presence 
  of 
  much 
  H 
  2 
  S 
  and 
  another 
  of 
  appreciable 
  amounts 
  of 
  

   S0 
  3 
  . 
  

  

  It 
  is 
  the 
  custom 
  for 
  beet 
  sugar 
  manufacturers 
  to 
  burn 
  their 
  

   own 
  lime 
  for 
  the 
  reason 
  that 
  the 
  carbon 
  dioxid 
  gas 
  is 
  also 
  used 
  

   in 
  the 
  process. 
  

  

  For 
  the 
  production 
  of 
  the 
  best 
  results 
  it 
  is 
  therefore 
  important 
  

   that 
  the 
  limestone 
  should 
  be 
  of 
  proper 
  quality 
  and 
  the 
  burning 
  

   conducted 
  in 
  the 
  right 
  manner. 
  

  

  Silica 
  is 
  a 
  deleterious 
  impurity 
  as 
  it 
  not 
  only 
  causes 
  the 
  stone 
  

   to 
  fuse 
  but 
  also 
  lowers 
  the 
  amount 
  of 
  lime 
  and 
  carbon 
  dioxid 
  

   produced 
  from 
  each 
  ton 
  of 
  stone 
  used. 
  This 
  latter 
  point 
  is 
  of 
  

   course 
  true 
  with 
  regard 
  to 
  any 
  other 
  impurities 
  which 
  may 
  be 
  

   present. 
  

  

  Too 
  little 
  fuel 
  should 
  also 
  be 
  avoided 
  as 
  it 
  decreases 
  the 
  

   amount 
  of 
  C0 
  2 
  produced.
