GLEANINGS  FROM  THE  FRENCH  JOURNALS. 
By  the  Editor. 
On  Tincture  of  Mustard. — It  is  well  known  that  a  solution  of 
volatile  oil  of  mustard  in  alcohol  is  a  good  rubefacient.  This  may 
be  procured,  more  economically,  according  to  M.  Barbet,  by 
macerating,  during  two  hours,  250  parts  of  black  mustard  flour  in 
500  parts  of  cold  water,  and  adding  afterwards,  125  parts  of  alcohol 
of  86° C,  and  distil  125  parts  of  distillate,  which  will  be  found 
to  possess  a  decided  rubefacient  action. — Jour,  de  Pharm.  de 
Bordeaux. 
Jelly  of  Codliver  Oil. — M.  Dufourmantle  proposes  the  following 
recipe  for  preparing  a  jelly  of  this  disagreeable  medicine.  Take  of 
codliver  oil,  30  grammes,  isinglass,  2  grammes,  water,  a  sufficient 
quantity  to  dissolve  the  isinglass.  When  the  latter  is  dissolved, 
add  the  oil  gradually,  stirring  constantly,  aromatizing  it  at  the  same 
time  with  anise  or  other  oil,  four  drops.  A  large  table  spoonful 
of  this  jelly  is  a  dose. — Jour,  de  Pharm,,  Janv.,  1864. 
Anti-asthmatic  paper. — Take  of  leaves  of  Belladonna,  stramo- 
nium, digitalis  and  sage,  each  five  grammes,  tincture  of  Benzoin, 
forty  grammes,  nitrate  of  potassa,  seventy-five  grammes,  water, 
one  thousand  grammes.  Make  a  decoction  or  infusion  with  the 
plants,  and  water,  dissolve  in  this  the  nitrate  of  potassa,  add  ihe 
tincture  of  Benzoin,  and  mix  them.  Into  this  plunge  the  paper, 
which,  should  be  unsized  and  spongy,  like  filtering  paper,  sheet 
by  sheet,  until  a  quire  is  introduced,  which,  after  twenty -four 
hours'  contact,  removed,  dried,  and  cut  into  squares  fcur  inches  long 
and  two  and  three-fourths  wide,  which  should  be  enclosed  in  boxes, 
each  containing  one  hundred  leaves.  Of  course  it  is  understood 
that  this  paper  is  to  be  used  by  burning  it  so  as  to  charge  the 
asmosphere  breathed  by  an  asthmatic  patient  with  the  products 
of  its  combustion  and  volatilization.    This  paper  is  sometimes
