48  8  Mixtures  of  Quinia  and  Ammonia.     { Amd™'^rm- 
tightly-fitting  stopper,  pour  upon  it  one  pint  of  water,  mixed  with  the 
water  of  ammonia,  macerate  for  forty-eight  hours,  then  transfer  it  to  a 
funnel  and  allow  the  liquid  to  drain  from  it,  and  add  sufficient  water 
until  two  pints  of  liquid  has  passed  ;  allow  it  to  stand  until  the  particles 
have  subsided,  then  decant  and  evaporate  to  eight  fluidounces,  filter 
and,  having  added  the  sugar,  dissolve  it  with  the  aid  of  heat. 
Experiments  were  made  with  the  ordinary  liquorice  root  and  the 
Russian  peeled  root,  and  of  the  two  the  syrup  made  from  the  Rus- 
sian root  is  decidedly  the  finest.  The  cortical  portion  of  liquorice 
root  is  acrid,  without  possessing  the  peculiar  virtues  of  the  root,  the 
Russian  root,  being  deprived  of  the  epidermis,  will,  of  course,  make 
the  best  preparation. 
The  syrup  thus  prepared  is  of  a  dark-brown  color,  and  contains  all 
the  sweet  principles  of  the  root  without  the  starch  and  other  inert 
matter.  It  is  used  to  mask  the  bitterness  of  quinia,  and  is  well  adapted 
for  children. 
Sulphate  of  magnesium,  iodide  and  bromide  of  potassium  loose  most 
of  their  taste  when  mixed  with  this  syrup. 
I  have  prepared  brown  mixture  from  liquorice  root  and  ammonia  by 
the  following  process : 
Take  of  Liquorice  root,  ...  4  troyounces 
Water  of  ammonia,  .  .  1  fluidounce 
Water,         .       .       .        .       q.  s. 
Proceed  in  the  same  manner  as  for  syrup  of  liquorice  root,  but  in- 
stead of  evaporating  to  eight  fluidounces,  evaporated  to  twelve  fluid- 
ounces,  and  mix  this  with  the  gum  arabic,  sugar  and  other  ingredients. 
Lastly,  add  water  of  ammonia  until  a  clear  solution  is  obtained,  taking 
care  not  to  add  an  excess. 
Brown  mixture,  prepared  by  the  above  process,  is  of  a  brownish- 
vellow  color,  and  almost  entirely  free  from  sediment. 
MIXTURES  OF  QUINIA  AND  AMMONIA. 
BY  WILLIAM  MciNTYRE,  PH.G. 
(  Read  at  Social  Meeting  of  Alumni  Association  of  the  College  of  Pharmacy,  Oct.  5,  1876.) 
While  quinia  and^ammonia  are  incompatible,  an  excess  of  the  latter 
will  determine  a  solution,  and  a  pharmaceutical  preparation  of  this 
character  is  not  an  impossibility.
