H02  Annual  Report  for  1910  of  the  Consulting  Chemist. 
occupy  thirteen  lines  only,  and  yet  are  quite  enough  for  the 
purpose,  and  avoid  the  minutiae  of  procedure  which  form 
such  a stumbling  block  in  the  carrying  out  of  the  English  Act. 
I have  had  occasion  to  draw  the  attention  of  the  Board 
of  Agriculture  to  the  practice,  sometimes  indulged  in, 
of  mixing  Bombay  cotton  seed  with  Egyptian,  and  to  the  sale 
of  the  manufactured  cake  under  the  name  of  “ Pure  Cotton 
Cake,”  without  any  qualification.  Similarly,  it  is  frequently  the 
practice  now  to  invoice  both  Egyptian  and  Bombay  cotton 
cake  as  “ Pure  Cotton  Cake.”  Inasmuch  as  the  difference  in 
price  between  the  two  classes  of  cake  is  considei-able,  it  seems 
to  me  very  desirable  that  it  should  be  incumbent  to  state  on 
the  invoice  whether  the  cake  is  made  from  Egyptian  seed,  from 
Bombay  seed,  or  from  a mixture  of  the  two.  It  would  appear, 
however,  that,  under  the  present  Act,  nothing  can  be  done, 
and  I can  only  advise  purchasers  of  Egyptian  cotton  cake 
to  be  careful  to  have  the  words  “ made  from  Egyptian  cotton 
seed  only  ” inserted  on  the  invoice. 
I now  give,  as  usual,  under  the  different  headings,  the 
most  prominent  matters  which  have  been  brought  to  my 
notice  during  the  year.

1.  Linseed  Cake. 
The  price  of  this  cake  has  risen  greatly,  and  this  has  some- 
times made  its  use  almost  prohibitive.  At  the  same  time  the 
cakes  that  have  passed  through  my 
hands  have  been,  as  a rule, 
very  pure  and  good. 
The  following  is  an  instance  of 
a pure  and  clean  cake  which 
was  guaranteed  to  contain  9 per 
cent  of  oil  and  29  per  cent.

The  price  of  this  was,  in  October,  1910,  9Z.  2s.  ()d.  per  ton 
delivered,  which  must  be  called  decidedly  cheap  under  the 
then  conditions. 
2.  Cotton  Cake. 
I have  on  several  occasions  noticed  that  Egyptian  cotton 
cake  has  been  very  hard.  Such  a cake  is  represented  by  the
