It  is  also  used  to  adulterate  olive  oil,  and  chemistry  has  found  no 
practical  mode  by  which  they  can  be  definitely  distinguished  apart. 
A  soap  has  been  made  of  the  residue  left  after  refining.  It  is  of  a 
more  or  less  dark  brown  color,  and  disagreeable  smell.  It  is  used  in 
the  laundry,  and  sells  from  three  to  seven  cents  a  pound,  according 
to  quality.  It  was  also  attempted  to  make  a  soap  from  the  white  oil. 
This,  when  first  manufactured,  is  of  a  handsome  white  color,  but  after 
standing  some  length  of  time  it  becomes  dark,  and  finally  almost  black. 
It  is  not  made  now. 
It  is  used  to  the  amount  of  ten  per  cent,  in  making  fancy  soaps,  to 
give  them  a  good  lather,  for  which  the  oil  is  said  to  be  the  best  known  ; 
but  even  in  this  small  amount  the  odor  of  the  rancid  oil  can  be  de- 
tected. 
The  hulls  are  used  for  fuel  in  the  factory,  and  the  greater  part  of 
the  cake  meal  was  sent  to  Europe,  the  farmers  of  this  country,  at  that 
time,  not  being  generally  acquainted  with  its  properties.  It  sold  for 
about  thirty  dollars  a  ton. 
A  few  years  ago,  the  oil  was  noticed  in  the  journals  in  connection 
with  preparations  of  pharmacy,  to  be  substituted  for  oils  in  liniments 
and  ointments,  for  which  it  is  adapted  by  its  properties  as  an  emol- 
lient, but  nothing  definite  was  arrived  at.  Being  cheaper  than  even 
the  commonest  grades  of  olive  oil,  and  resembling  it  so  much  in  its 
behaviour,  it  is  peculiarly  fitted  for  the  preparations  of  the  pharmaco- 
poeia in  which  the  olive  oil  is  used.  Mixed  with  aqua  ammoniae  in  the 
officinal  quantities  for  "Liniment.  Amnionic,"  it  makes  a  product 
which  has  all  the  essential  properties  that  are  indicated  by  the  olive 
oil,  and  has  the  advantage  of  not  forming  so  thick  a  mixture,  thereby 
making  it  more  convenient.  In  the  "Lin,  Camphors,"  it  seems  to 
serve  exactly  the  same  purpose  as  the  officinal  oil. 
Lead  plaster  made  with  the  cotton-seed  oil  has  been  substituted 
with  advantage  for  the  officinal,  and  has  been  used  to  mix  with  it  to 
the  amount  of  fifty  per  cent*  by  some  manufacturers  of  the  plaster. 
This,  made  with  the  cotton-seed  oil  alone,  forms  a  handsome,  light 
colored  plaster,  apparently  equal  in  all  respects  to  the  English,  with 
the  exception  that  it  does  not  become  hard  enough  to  keep  its  shape, 
in  the  usual  form  of  selling  it.  But  when  mixed  with  olive  oil  in  equal 
proportions,  this  difficulty  is  entirely  overcome. 
The  cost  of  the  plaster  made  with  the  cotton-seed  oil,  using  the  best 
English  litharge,  is  twenty  cents  per  pound.    This  difference  in  the
