soil  8*100  to  10-000  kilograms  of  the  plant  might  be  obtained  per

Distilled  orange  floiver  water.* — L.  Malenfant  observed  that  fresh 
-orange  flowers,  mixed  with  cold  water,  yield,  on  distillation  over  the 
naked  fire,  a  milky  water,  possessing  a  somewhat  empyreumatic  odor 
and  a  strong,  somewhat  acrid  taste.  Kept  for  twelve  or  eighteen 
months  in  glass  vessels  covered  with  parchment,  it  loses  its  empy- 
reuma,  and  after  filtering  has  an  agreeable  odor  and  taste. 
If  the  flowers  are  mixed  with  boiling  water  and  immediately  dis- 
tilled the  water  is  limpid,  and  gradually  separates  some  thick  oil  of  a 
brownish  color ;  the  water  has  odor  and  taste  of  the  flowers,  but  com- 
plicated with  a  still  smell  {gout  de  feu),  which  it  loses  after  long 
keeping ;  it  seems  to  alter  less  rapidly  than  that  obtained  by  the 
former  process. 
Distilled  by  steam  a  limpid  water  of  a  pure  odor  and  taste  is  at 
once  obtained,  free  from  empyreuma ;  it  may  be  at  once  used,  and 
keeps  better  in  the  light  than  when  obtained  by  the  two  former  pro- 
cesses.— L'  Union  Pharm.,  1873,  Feb. 
ON  THE  USE  OF  DRY-POWDERED  BLOOD. 
By  Dr.  de  Pascale,  of  Nice. 
Several  years  ago  I  published  from  my  experience  and  medical 
practice,  some  observations  on  the  very  beneficial  effect  of  warm  blood 
taken  the  moment  when  extracted  from  the  calf  or  ox,  killed  for  gen- 
eral domestic  use. 
I  mentioned  at  that  time  the  cases  of  three  invalids,  not  English,
