Annual  Report  for  1909  of  the  Consulting  Chemist.  343 
This  is,  however,  as  I have  said,  the  only  instance  brought 
to  my  notice,  and  I am  of  opinion  that  the  possibility  of  harm 
arising  from  this  source  has  been  considerably  exaggerated. 
2.  Cotton  Cake  {Undecorticated). 
Cotton  cake,  though  its  price  has  somewhat  increased,  has 
continued  to  be,  on  the  whole,  of  good  quality.  The  class 
of  cotton  cake  generally  known  as  “ Bombay  ” cake  has  also 
mostly  been  of  improved  manufacture.  Occasionally  it  still 
happens  that  “Bombay”  cake  is  substituted  for  “ Egyptian,” 
but  this  is  exceptional.  In  one  such  instance  brought  to  my 
notice,  cake  had  been  sold  as  “ Pure  Egyptian  97  per  cent.” 
at  6Z.  per  ton,  but  I found  it  to  be  made  of  “ Bombay  ” seed. 
Though  this  allegation  was  at  first  denied,  it  was  ultimately 
allowed  and  the  difference  of  value  given.  It  seems  that  the 
Hull  firm  originally  supplying  it  described  it  as  “ made  of 
Egyptian  and  other  seed.”  All  such  loose  forms  of  guarantee 
should  be  avoided. 
3.  Cotton  Cake  {Decorticated). 
The  supply  of  this  has  been  alike  limited  and  unsatisfactory. 
One  looks  now  in  vain  for  the  prime  decorticated  cotton  cake 
of  the  past,  which  was  so  valuable  an  asset  to  the  farm,  and 
there  would  moreover  seem  but  little  hope  of  a return  to 
the  former  good  quality  of  cake,  the  present  deliveries  being 
almost  without  exception  hard  and  badly  decorticated.  The 
conditions  under  which  the  cake  is  brought  to  this  country 
and  sold  (chiefly  at  Liverpool)  are  very  unsatisfactory,  and 
provide  no  real  guarantee  for  the  farmer,  inasmuch  as  there 
exists  no  limit  whatever  as  to  the  extent  to  which  fibre  may 
be  included,  or,  in  other  words,  no  standard  of  “decortication.” 
So  it  comes  about  that  one  may  meet  with  a cake  or  meal 
sold  as  “ decorticated  ” but  which  is  really  little  better  than 
“ undecorticated.”  Such  cases  were  the  following  : —
