On  Santo nate  of  Quinia  and  Cinchonia.  By  M.  Pavesi. — It  is  well 
known  that  santonin  is  a  substance  analogous  to  the  fatty  acids,  and  allied 
in  a  certain  extent  to  the  volatile  oils,  without  acid  reaction,  but  forming 
with  bases  ( potassa,  soda,  magnesia,  baryta)  salts  which  crystallize.  This 
is  the  case  also  with  the  alkaloids  quinia  and  cinchonia.  The  author  takes 
to  make  the  latter  salts,  pure  santonin,  and  pure  cinchonia  (or  quinia), 
each  12 \  drachms,  ivory  black  2±-  drachms,  alcohol  36°  B.,  2  pounds 
(avoir.),  boil  them  together  in  a  small  alembic  for  a  few  minutes,  filter  the 
solution  through  paper,  and  distil  at  a  moderate  heat  in  a  water-bath  till 
reduced  to  25  ounces.  It  is  then  removed  from  the  fire  to  a  cool  place  and 
left  for  24  hours,  that  the  santonate  of  cinchonia  may  crystallize.  It  is  then 
removed  to  a  filter,  and  the  crystals  dried  after  drainage. — Revue  Pharma-

Nitrous  Fumigating  Powder. — Take  of  bi-sulphate  of  potassa  15  parts, 
nitrate  of  potassa  13  parts.  Pulverize  the  substances,  mix  them  well  and 
add  a  sufficient  quantity  of  oxide  of  manganese  to  blacken  the  mixture. 
In  using  this  powder  it  is  thrown  pinch  by  pinch  on  a  hot  brick.  Im- 
mediately abundant  vapors  of  nitric  and  hyponitric  acids  are  disengaged.

Ferrated  Protein. — This  compound  has  recently  been  employed  in  France. 
It  is  obtained  by  coagulating  the  albumen  of  eggs  by  means  of  nitric  acid, 
washing  the  coagulum  with  very  dilute  muratic  acid  1  part  to  100,  till  all 
soluble  matter  is  removed,  then  dissolving  it  in  a  solution  of  caustic 
potassa,  containing  1  part  in  a  100,  at  the  temperature  of  122°  Fahr,  The 
albumen  thus  dissolved,  is  then  precipitated  agriin  by  strong  acetic  acid 
and  the  coagulum  washed  with  distilled  water  till  it  ceases  to  contain 
acetate  of  potash,  and  is  then  dried  in  a  stove.  Thus  prepared  it  is  white, 
tasteless,  and  odorless,  and  readily  attracts  moisture  from  the  air  and  should 
be  preserved  in  close  bottles. 
Ferrated  protein  is  obtained  by  triturating  together  equal  parts  of  this 
powder  and  iron  by  hydrogen.  It  should  be  kept  closely  bottled,  as  it 
attracts  moisture,  which  rapidly  oxidizes  the  iron.  The  dose  is  from  2  to 
5  grains  daily  for  an  adult.— Revue  Pharmaceutique,  1857.

the  approval  of  the  Academy  of  Medicine  at  Turin,  as  one  of  the  most
