GALENICAL  PREPAEATIONS  OF  THE  GEKMAN  PHAE- 
MACOPCEIA. 
In  the  following  we  propose  to  publish  from  the  new  German  Phar- 
macopoeia the  formulas  of  such  preparations  for  which  no  equivalent 
one  is  contained  in  the  new  Pharmacopoeia  of  the  United  States^, 
reserving  for  another  paper  a  comparison  of  those  preparations  which 
are  found  in  both.  The  alcohol,  spiritus,  of  the  German  Pharmaco- 
poeia, has  the  density  '830  to  '834  at  15°C.  and  contains  between  91*2 
and  90*0  per  cent,  by  measure,  or  between  87  2  and  85*6  per  cent,  hj 
weight  of  absolute  alcohol.  When  water  is  directed,  distilled  water  is 
to  be  used.  All  preparations  are  made  by  weight.  The  exhaustion  of 
drugs  is  effected  by  maceration,  usually  continued  for  eight  days,  when 
the  dregs  are  expressed  and  the  liquid  is  filtered ;  the  deficiency  in; 
liquid  is  not  made  up  by  the  subsequent  addition  of  menstruum ;  hence 
the  proportions  given  are  those  of  drug  to  menstruum,  not,  as  in  the 
U.  S.  Pharmacopoeia,  of  drug  to  finished  preparation — and  the  weight 
of  the  resulting  preparation  really  is  in  excess  of  the  menstruum,  the' 
excess  corresponding  to  the  weight  of  the  soluble  matter  taken  up,, 
while  on  the  other  hand  a  portion  of  the  preparation  is  lost  by  being 
retained  in  the  powder  and  in  the  presscloth. 
Acetum  Aromaticum. — Oil  of  lavender,  peppermint,  rosemary,  juni- 
per and  cinnamon  of  each  1  part ;  oils  of  lemons  and  cloves,  each  2 
parts;  alcohol  300  parts;  acetic  acid,  sp.  gr.  1*041,  450  parts;  water 
1,200  parts.  Dissolve  the  oils  in  the  alcohol,  add  the  acid  and  water,, 
shake  the  turbid  mixture  occasionally  during  several  days  and  filter. 
It  is  colorless,  does  not  become  turbid  on  the  addition  of  water  and  has 
the  specific  gravity  *987  to  *991. 
Acetum  Digitalis. — Digitalis  leaves,  finely  cut,  5  parts ;  alcohol  5 
parts;  acetic  acid,  sp.  gr.  1*041,9  parts;  water  36  parts.  Macerate 
for  eight  days,  express  and  filter.  It  is  brownish-yellow  and  has  an 
acid  and  very  bitter  taste.  Maximum  dose,  single  2*0  grams ;  per 
day  10*0  grams. 
Acidum  Carholicum  Liquef actum. — Crystallized  carbolic  acid  100^ 
parts ;  water  10  j)arts  ;  mix. 
Ammonium  Chloratum  Ferratum. — Chloride  of  iron  and  ammonium.. 
Ammonium  chloride  32  parts;  solution  of  ferric  chloride,  sp.  gr^ 
1*280  to  1*282,  containing  10  per  cent,  of  iron,  9  parts.  Mix  and,  with 
constant  agitation,  evaporate  to  dryness  by  means  of  a  steam  bath.  It:
