is  a  very  simple  one :  10  lozenges  are  reduced  to  a  fine  powder  and 
digested  with  chloroform  in  a  small  flask  for  half  an  hour.  The 
chloroform  solution  is  then  filtered,  the  residue  upon  the  filter  washed 
two  or  three  times  with  chloroform,  and  the  solutions  evaporated  with 
the  aid  of  a  gentle  heat.  The  santonin  remains  in  a  pure  crystalline 
state.  According  to  the  Codex  each  lozenge  should  contain  25  milli- 
grams of  santonin,  but  the  examination  showed  that  not  one  of  the 
samples  contained  more  than  10  milligrams  in  each  lozenge. — Pharm.

Pasta  Mack  is  a  new  toilet  preparation  which  dissolves  in  wa- 
ter with  evolution  of  carbonic  acid  gas,  and  is  said  to  produce  an  agree-

Berl.  Pharm.  Ztg,  it  is  composed  of  a  mixture  of  27  parts  rice  starch 
and  "73  parts  effervescing  powder,  (bicarbonate  of  sodium  10,  tartaric

the  skin  long  after  washing. — Rundschau,  Prag,  1888,  p.  12.

Flashpotvder,  (Blitzpulver)  used  in  photography  for  taking  in- 
stantaneous pictures,  is  made  by  mixing  together  coarsely  crushed  su-

parts.  This  powder,  according  to  Harvey,  in  Pharm  Ztg.,  is  one  of 
the  best  for  this  purpose,  but  care  must  be  taken  that  the  sugar  is  not 
in  fine  powder,  as  otherwise  the  explosions  will  be  too  violent.  In
