YELLOW  POPPY  SEED  OIL. 
rain  water  coming  from  the  roofs  runs  into  the  troughs,  pene- 
trates  into  the  sand  through  the  rills,  and  is  thus  filtered  into 
the  cylinder  or  well-hole  by  the  conical  holes  already  described. 
The  water  thus  supplied  is  perfectly  limpid,  sweet,  and  cool

YELLOW  POPPY  SEED  OIL. 
M.  Cloez,  of  Paris,  has  recently  made  known  the  result  of 
some  experiments  relative  to  the  Yellow  Horned  Poppy,  G^lau- 
cium  luteum,  Scop.,  which  T  found  on  some  parts  of  our  shores. 
It  is  common  all  round  the  Mediterranean,  and  up  the  Western 
Coast  of  Europe  to  Scandinavia.  It  expands  its  handsome 
yellow  flowers  during  July  and  August,  which  are  succeeded  by 
elongated  capsules,  containing  a  large  number  of  minute  seeds. 
These  seeds  lose  only  8  per  cent,  water  when  dried  in  an  oven  ; 
and,  after  drying,  contain  42  per  cent,  of  a  siccative  oil,  which  can 
be  used  as  an  aliment,  or  for  burning.  In  its  ordinary  state  the 
seed  yields  by  pressure  32  per  cent,  of  this  oil.  The  marc,  or 
residue,  constitutes  a  valuable  manure,  giving,  on  analysis,  six 
per  cent,  of  nitrogen,  and  an  ash,  amounting  to  14J  per  cent., 
rich  in  phosphate  of  lime.  This  oil,  without  doubt,  resembles 
greatly  the  poppy-seed  oil,  obtained  from  Papaver  somniferum, 
and  the  plant  might  be  cultivated  for  the  sake  of  its  seed  on  our 
sandy  shores,  where  nothing  else  remunerative  can  be  produced, 
but  we  question  whether  it  would  yield  anything  like  as  much  seed 
per  acre  as  the  opium  poppy,  and,  therefore,  whether  it  would  pay 
to  cultivate  it  for  that  purpose.  M.  Cloez's  results,  however,  are 
worthy  of  being  recorded. —  London  Pharm.  Journ.  Nov,  1860.

HYPOCHLORITE  OF  ALUMINA. 
Orioli  recommends  hypochlorite  of  alumina  to  be  used  as  a 
bleaching  and  disinfecting  agent,  instead  of  the  hypochlorite  of 
lime  and  soda.  It  destroys  more  promptly,  he  says,  organic 
coloring  matter  and  gaseous  matters  of  a  mephitic  nature. —
