FORMULAS  and  PREPARATIONS  of  new  MEDICAMENTS, 
By  the  Editor. 
In  continuation  of  the  formulas  discussed  and  adopted  by  the  Paris 
Pharmaceutical  Society  (see  p.  233),  we  select  the  following  : 
Solution  of  sodium  phenate  [Phenol  sodique.) — Phenic  acid  70 
grams,  caustic  soda  30  grams  ;  water  sufficient  to  make  1  liter. 
Syrup  of  Chloral  Hydrate. — Dissolve  50  grams  of  crystallized 
chloral  hydrate  in  950  grams  of  orange-flower  syrup.  A  tablespoonful 
(20  grams)  contains  1  gram  of  chloral  hydrate. 
Tincture  of  Quillaia. — 100  grams  of  quillaia  bark  are  digested  in 
500  grams  of  alcohol  in  a  suitable  apparatus,  placed  in  a  water-bath, 
the  temperature  being  maintained  near  the  boiling  point  for  half  an 
hour  ;  the  whole  is  then  macerated  for  48  hours  with  occasional  agita- 
tion and  afterwards  filtered.  The  tincture  is  mainly  employed  in 
preparing  emulsions  of  substances  insoluble  in  water,  such  as  copaiba, 
tar,  oil  of  cade,  which  are  made  according  to  the  formula  for 
Emulsion  of  Tolu  Balsam. —  Dissolve  2  grams  of  balsam  of  tolu 
in  10  grams  of  90  per  cent,  alcohol,  add  10  grams  of  tincture  of 
quillaia  and  mix  with  78  grams  of  hot  water. 
Preparations  of  Eucalyptus  Globulus. — The  infusion,  wine,  elixir 
and  extract  are  made  from  eucalyptus  leaves,  in  the  same  manner  as 
the  corresponding  preparations  of  coca,  (see  p.  236.) 
Water  of  Eucalyptus. — Distil  1  part  of  dry  eucalyptus  leaves  with 
sufficient  water  to  obtain  4  parts  of  distillate. 
Syrup  of  Eucalyptus. — Infuse  50  grams  of  eucalyptus  leaves  for  three 
hours  with  sufficient  water  to  obtain,  after  expression  and  filtration,  250 
grams  of  infusion,  add  100  grams  of  distilled  eucalyptus  water  and 
dissolve  in  the  liquid  650  grams  of  sugar,  using  a  covered  vessel  placed 
in  a  water-bath. 
Tincture  of  Physostigma. — Macerate  100  parts  of  powdered 
Calabar  bean  in  500  parts  of  80  per  cent,  alcohol  for  10  days  ;  express 
and  filter. 
Glycerite  of  extract  of  physostigma  is  made  in  three  different 
proportions.  The  alcoholic  extract  of  Calabar  bean  is  well  mixed 
with  10,  20  or  100  times  its  weight  of  glycerin  and  dissolved  by  the 
aid  of  a  moderate  heat.     It  should  be  completely  dissolved.
