ELIXIR  AROMATICUM. 
By  WmiAM  G.  Topus. 
The  formula  for  the  preparation  of  Elixir  Aromaticum  is  one  of  the 
greatest  time-consumers  in  the  United  States  Pharmacopoeia.  The 
continued  filtration  and  refiltration  of  the  product,  particularly  where 
considerable  quantities  are  made,  requires  the  prolonged  presence 
of  material  and  apparatus  upon  the  working  table,  often  using  space 
needed  for  other  purposes.  This  needless  sacrifice  of  time  prompted 
me  to  seek  a  short  cut  in  the  preparation  that  would  make  no 
sacrifice  of  its  properties,  yet  expedite  its  manufacture.  As  a  result 
of  thought  and  experiment  on  the  subject  I  submit  the  following  for 
your  consideration : 
Take  of 
Purified  talcum  ...   30  grams. 
Comp.  sp.  orange   12  c.c. 
Alcohol  238  cc. 
Distilled  water  563  c.c. 
Sugar  375  grams. 
Mix  the  comp.  sp.  of  orange  with  the  purified  talcum  (personally 
I  prefer  magnesium  carbonate).  To  this,  in  a  mortar,  add  gradually 
the  water  and  alcohol  previously  mixed  after  the  manner  of  making 
medicated  waters,  transfer  to  a  wetted  filter  and  when  the  filtrate  has 
passed  make  it  up  with  distilled  water  through  the  filter  to  measure 
818  c.c,  then  add  the  sugar  and  dissolve  by  agitation,  or  the  sugar 
may  be  percolated  with  the  filtrate  it  preferred.  This  method 
makes  a  clear  bright  preparation  and  it  may  be  finished  in  about  15 
minutes  up  to  the  addition  of  the  sugar. 
PASTING  LABELS  ON  TIN. 
By  Wiluam  G.  Topus. 
After  thirty  years  of  experience  with  labels  curling  off  from  metal 
surfaces,  and  alter  some  minutes  of  careful  thought  upon  the  subject, 
I  came  to  the  conclusion  that  the  reason  for  this  undesirable  condi- 
tion was  centered  in  the  contracting  of  the  paste,  consequent  upon 
its  drying.  Therefore,  I  reasoned,  that  if  it  were  possible  to  prevent 
extreme  desiccation  the  label  should  adhere  to  metal  as  well  as 
other  surfaces.    Accordingly  I  sought  to  accomplish  this  by  mixing
