GLEANINGS  FROM  THE  FRENCH  JOURNALS. 
pistils  are  afterwards  exposed  to  the  sun,  then  rolled  with  the 
hands  in  balls  whilst  they  are  yet  sticky,  and  then  enclosed  in 
sacks  of  leather  or  goatskin  and  sent  to  Constantinople,  where 
they  are  inspected  and  the  desiccation  completed. 
Extraction  of  Olive  Oil  by  means  of  Sulphur  et  of  Carbon.^- 
M.  Loutsoudie,  taking  advantage  of  the  great  solvent  power  and 
volatility  of  bi-sulphuret  of  carbon,  has  succeeded  in  using  it 
advantageously  in  extracting  olive  oil  from  the  fruit,  and  in 
purifying  the  oil.  The  bi-sulphuret  is  previously  treated  with 
acetate  of  lead. 
False  Digitalis.— M..  Timbal-Lagrave,  Pharmacien  of  Tou- 
louse, states  (Repertoire  de  JPharmacie,  March,  1858)  that  the 
radical  leaves  of  Conyza  Squarrosa  have  been  found  mixed  with 
those  of  digitalis  as  a  sophistication.  There  is  considerable 
analogy  in  the  appearance  of  the  leaves,  but  on  analysis  they 
were  discovered  to  contain  no  digitalin. 
Granules  of  subnitrate  of  Bismuth. — M.  Mentel  suggests 
the  granulation  of  subnitrate  of  bismuth  as  a  form  for  adminis- 
Mng  that  substance.  Equal  parts  of  pure  subnitrate  and 
sug**  are  intimately  mixed  and  heated  until  the  sugar  fuses 
sufficieijs.Vy  to  granulate,  avoiding  carefully  so  much  heat  as  to 
caramelize  \Q  sugar.  In  this  form  subnitrate  of  bismuth  is 
taken  with  gre^.  facility,  and  easily  divided  in  doses  by  measure 
or  weight.— Rep.  ie  Pharm. 
Mechanical  Analysih^JM..  Lassaigne  proposes  the  use  of 
chloroform  as  a  means  ot  separating  mineral  substances  from 
starch  when  mechanically  mix^d.  Owing  to  the  greater  gravity 
of  the  latter,  the  fecula  floats  cn  the  chloroform,  whilst  the 
mineral  body  sinks  to  the  bottom  *nd  may  thus  be  separated. 
The  operation  is  best  performed  in  a  glafca  tube  closed  at  one  end. 
The  idea,  thus  brought  forth  by  M.  Lassaigne,  he  says  is  due  to 
M.  Cailletet  of  Charleville  Rep.  de  Pharm. 
Necessity  of  labelling  Medicines.— k  physician  of  the  district 
of  Tourney  (Belgium)  has  been  condemned  by  the  court  of  that 
city  to  pay  a  fine  of  200  francs,  for  having  given  a  violent 
medicine  to  a  young  boy  who  had  the  itch,  and  for  not  having
