  oil 
  are 
  obtained, 
  and 
  the 
  soluble 
  parts 
  of 
  the 
  superphosphate 
  are 
  

   combined 
  to 
  better 
  advantage 
  with 
  the 
  gelatinous 
  and 
  nitrogenous 
  mat- 
  

   ters, 
  the 
  oil 
  being 
  subsequently 
  separated 
  from 
  such 
  matters 
  and 
  the 
  

   soluble 
  parts 
  of 
  the 
  superphosphate 
  by 
  skimming, 
  and 
  the 
  cooked 
  mass 
  

   being 
  pressed 
  to 
  squeeze 
  out 
  liquor 
  and 
  oil. 
  Furthermore, 
  by 
  the 
  pres- 
  

   ent 
  procedure, 
  the 
  insoluble 
  parts 
  of 
  the 
  superphosphate 
  are 
  at 
  the 
  same 
  

   time 
  mixed 
  with 
  the 
  fish 
  scrap 
  or 
  pomace, 
  whereas 
  by 
  the 
  former 
  pat- 
  

   ented 
  process 
  this 
  mixture 
  had 
  to 
  be 
  effected 
  at 
  another 
  time 
  and 
  at 
  an 
  

   increased 
  expense.

  : 
  

  

  " 
  Consequently 
  I 
  do 
  not 
  herein 
  claim 
  to 
  first 
  press 
  from 
  the 
  fish 
  the 
  

   oil 
  and 
  gelatinous 
  and 
  nitrogenous 
  liquid, 
  and 
  afterward 
  mix 
  with 
  the 
  

   said 
  liquid 
  a 
  superphosphate, 
  and 
  remove 
  from 
  the 
  mixture 
  the 
  insoluble 
  

   substance 
  or 
  substances, 
  and 
  evaporate 
  the 
  remainder 
  to 
  the 
  necessary 
  

   consistency. 
  My 
  new 
  process 
  involves 
  the 
  employment 
  of 
  heat 
  and 
  the 
  

   cooking 
  of 
  the

  "In 
  the 
  manufacture 
  of 
  liquid 
  fertilizer, 
  the 
  process 
  of 
  obtaining 
  

   from 
  fish 
  its 
  gelatinous 
  and 
  nitrogenous 
  properties, 
  combined 
  with 
  the 
  

   soluble 
  parts

  a 
  superphosphate, 
  such 
  consisting 
  in 
  mixing 
  together 
  

   the

  cooking 
  the 
  mixture 
  by 
  heat 
  and 
  sub- 
  

   sequently 
  subjecting 
  it 
  to
