The  first  requisite  is  the  selection  of  fresh  essential  oils.  An  aro- 
matized water  made  from  a  stale  and  terebinthinous  oil  is  the  worst' 
advertisement  a  pharmacist  can  have,  whilst,  if  a  fresh  oil  is  at  hand, 
even  an  aromatized  orange  water  can  be  made  which  will  serve  many 
good  purposes.  The  writer  has  used  an  orange  water  made  in  the 
usual  manner  with  considerable  satisfaction,  and  a  very  useful  simple 
elixir  resembling  Curacoa  Cordial  may  be  made  by  taking  of 
Aqua  Aurantii        in  a  pint)  f^iss.

Mix. 
Some  formulas  for  simple  elixirs  direct  the  essential  oils  to  be  mixed 
with  the  spirit,  and  then  a  certain  proportion  of  sugar  and  water 
added  and  filtered.  Tho  great  objection  to  those  made  in  this  way  is 
that  when  such  are  used  in  prescriptions  with  water  in  combination 
(and  it  is  generally  used  in  this  way),  a  separation  of  the  excess  of  oil 
takes  place,  which  renders  the  preparation  unsightly. 
A  delicately  flavored  syrup  of  citric  acid  may  be  made  which  will 
be  clear  and  bright,  not  disfigure  the  sides  of  the  bottle,  nor  have  the 
harshness  that  the  officinal  article  possesses. 
To  make  this,  double  the  quantity  of  fresh  oil  of  lemon  prescribed, 
by  the  officinal  formula  should  be  rubbed  up  with  a  small  quantity  of 
carbonate  of  magnesium,  a  little  water  added,  thrown  on  a  filter,  then 
followed  by  more  water,  sufficient  to  form  with  the  sugar  and  citric 
acid  the  syrup  of  officinal  strength. 
Compound  aromatic  waters  are  readily  made,  containing  caraway,, 
coriander,  cinnamon,  orange  and  orange-flower  flavors,  and  form  a 
means  of  preparing  the  host  of  elixirs  that  are  now  required : — 
The  mixed  alkaloids  to  be  dissolved  in  cologne  spirit,  syrup  added,, 
and  the  salt  soluble  in  water,  dissolved  in  the  aromatic  water.
