ON  THE  SYRUPS  OF  ORANGE  PEEL,  ETC. 
Dissolve  the  salts  separately  each  in  half  a  pint  of  water,  and  add 
the  solution  of  phosphate  of  soda  to  the  solution  of  sulphate  of 
manganese  as  long  as  it  produces  a  precipitate,  which  wash  with 
cold  water  and  dissolve  by  means  of  the  chlorohydric  acid; 
dilute  till  it  measures  seven  fluid  ounces,  then  add  sugar  sufficient 
to  make  up  the  bulk  of  twelve  and  a  half  fluid  ounces.

ON  THE  PREPARATION  OF  THE  SYRUPS  OF  ORANGE  PEEL, 
TOLU  AND    GINGER,  AND  ON    THE    SYRUP  AND  FLUID 
EXTRACT  OF  VANILLA. 
Rj  William  Procter,  Jr. 
When  an  aromatic  tincture,  made  with  alcohol  of  sp.  grav. 
.835,  holding  in  solution  volatile  oil,  resin,  extractive  and  other 
principles,  is  suffered  to  evaporate  spontaneously,  a  considerable 
portion  of  the  alcohol  may  be  separated  without  occasioning 
much  precipitation  of  these  principles.  If,  now,  such  a  partially 
evaporated  tincture  be  triturated  with  a  mixture  of  carbonate  of 
magnesia  and  sugar,  and  water  be  gradually  added,  the  odorous 
and  sapid  principles  are  dissolved  to  a  large  extent,  and  by 
filtration  a  transparent  liquid  is  obtained,  containing  but 
little  alcohol,  and  which  forms  with  pure  sugar  a  perfectly 
transparent  syrup,  highly  charged  with  the  aroma  and  taste  of 
the  substances  treated. 
The  idea  of  using  carbonate  of  magnesia  as  an  inter-medium, 
in  preparing  the  aromatic  waters,  has  long  been  in  use,  but  its 
application  to  the  preparation  of  liquids  f  jr  syrups  was  first 
suggested  in  print  by  John  D.  Finley,  (Amer.  Jour.  Pharm,  vol. 
23,  page  219,)  yet  he  makes  no  provision  for  the  removal  of  the 
alcohol. 
By  adopting  the  idea  above  sketched  forth,  a  number  of  syrups 
can  be  prepared,  so  as  to  produce  their  aromatic  qualities  in  per- 
fection.
