252  Annual  Report  for  1904  of  the  Consulthuj  Chemist. 
3.  Decortiexded  Cotton  Cake. 
The  oft-repeated  complaint  continues  that  it  is  extremely 
hard  to  get  a decorticated  cotton  cake  of  good  quality,  soft  in 
texture,  free  from  lumps,  and  well  decorticated.  Occasionally 
good  cakes  come  to  the  fore,  but  these,  as  instanced  in  the 
following  case,  are,  I believe,  manufactured  in  this  country  by 
a special  process  to  which  I have,  in  previous  years,  drawn 
attention  : — 
Moisture  ......  7‘90 
Oil 18-.36 
'Albuminous  compounds  (flesh-forming 
matters  ......  36‘75 
Carbohydrates,  &c.  ....  24‘79 
Woody  fibre  (cellulose)  . . . 5'30 
^Mineral  matter  (ash)  . . • . . 3-90 
100-00 
'Containing  nitrogen  ....  5’88 
including  sand  .....  -80 
This  cake  was  sold  as  “ English  decorticated  cotton  cake,” 
and  the  price  was  11.  Is.  6d.  per  ton  in  January,  1904. 
4.  Maize. 
The  following  analyses  of  samples  of  three  different  kinds 
of  maize  (unground),  American  flat.  River  Plate,  and  Danubian, 
may  be  of  interest.  It  should  be  remarked,  however,  that  it 
is  not  alone  the  chemical  composition,  but  also  the  relative 
“ hardness  ” of  samples,  that  must  be  taken  into  consideration 
when  comparing  such  samples.  The  flat  American  maize  was 
much  the  best  in  this  latter  respect,  and  it  will  be  noted  that 
it  was  the  richest  in  starch  and  the  lowest  in  albuminoids.
