or  12  grams  of  dialyzed  stearin  soap,  to  320  grams  of  alcohol.  G. 
Berg  considers  these  quantities  of  dialyzed  soap  too  small,  and  states 
that  opodeldoc,  thus  prepared,  will  become  partially  liquid  during  the 
hot  season;  he,  therefore,  increases  the  proportion  to  20  parts  oil- 
tallow  soap,  or  16  stearin  soap,  to  320  parts  alcohol,  and  thus  obtains 
the  preparation  permanently  transparent,  clear  and  solid. — Pharm.  Ztg,^

Syrupus  glycyrrhizae,  corresponding  in  strength  to  the  syrup  offi- 
cinal in  the  German  Pharmacopoeia,  but  being  clearer  and  more  elegant 
if  prepared  carefully,  is  made  by  H.  Reinige  by  dissolving  i  part  of 
purified  extract  of  liquorice  in  i  part  of  distilled  water,  and  adding  17 
parts  of  simple  syrup  and  12  parts  of  purified  honey. — Pharm.  Ztg.^

R.  Scherff  recommends  boiling  for  a  few  minutes  3J  pounds  of  honey 
with  I J  pounds  of  water,  5  grams  of  Irish  moss  and  O'lO  of  tannin, 
straining  through  a  woolen  cloth,  adding  sufficient  water  to  the  strained 
mixture  to  make  it  weigh  6  pounds,  dissolving  in  it  3J  pounds  of  sugar 
by  heating  gently,  straining  through  linen,  adding  to  the  cooled  liquid 
10  grams  of  purified  extract  of  liquorice  root,  dissolved  in  25  grams  of 
warm  water,  and  25  grams  of  alcohol  and  filtering. — Pharm.  Ztg..^  Oct.

The  Active  Constituent  of  Insect-Powder  (see  ''Amer.  Jour. 
Pharm.,"  1877,  p.  17). — G.  dal  Sie  has  been  studying  the  constituents 
of  Pyrethrum  (Chrysanthemum)  cinerariaefolium  since  1 873,  and  found  it 
to  contain  a  volatile  acid  soluble  in  ether,  alcohol  and  water,  which 
seems  to  exist  in  a  free  state  in  the  plant.  Ether  extracted  a  crystal- 
lizable  acid  and  also  an  aromatic  acid,  having  an  oily  consistence  at  the 
ordinary  temperature.  Alcohol  extracted  a  resinous  substance,  which 
was  decomposed  by  dilute  sulphuric  acid  into  sugar  and  another  product. 
The  author  is  still  continuing  his  investigations,  but  feels  convinced 
that  the  volatile  acid  is  the  active  principle. — Pharm.  Centralh.^  Oct.  2,

Estimation  of  Morphia  in  Opium. — E.  Mylius  proposes  a  modi- 
fication of  FlUckiger's  process  as  follows  :  8  grams  of  powdered  opium, 
air-dry,  are  macerated  with  80  grams  of  water  for  12  hours,  and  42*5 
grams  of  the  filtrate  (=4  grams  of  opium)  are  mixed  in  a  flask  having
