the  residue  found  to  amount  to  1*46  per  cent.,  whicli  lost  nothing  on 
heating  to  110°C.  The  residue  from  another  portion  was  treated  with 
water,  which  acquired  a  bitter  taste ;  the  dissolved  principle  will  be 
treated  under  the  alcoholic  maceration  as  this  dissolved  a  larger  quan- 
tity. The  residue  from  the  ethereal  solution  was  completely  soluble 
in  strong  alcohol,  cliloroform,  benzol,  aqueous  and  alcoholic  potassium 
hydrate  solution.  The  alcoholic  solution  was  precipitated  by  distilled 
water  and  also  by  acidulated  water.    The  extract  was  principally  resin. 
3.  Absolute  Alcohol  maceration. — The  residual  powder  from  the 
above  maceration  Avas  treated  with  the  necessary  quantity  of  absolute 
alcohol.  The  dried  extract  was  equal  to  5  per  cent.,  whicli  lost  nothing 
on  heating  to  1 10°C.  The  air-dried  residue  was  treated  with  water 
heated  slightly  and  allowed  to  macerate  for  24  hours.  The  water  had 
assumed  an  acid  reaction  and  a  yellow  color  which  was  turned  to  a 
yellowish  brown  by  ammonia  water.  The  portion  soluble  in  water 
amounted  to  4*29  per  cent.  The  aqueous  solution  was  acidified  and 
shaken  with  petroleum,  benzol  and  chloroform.  The  liquid  was  after- 
ward made  alkaline  and  shaken  with  the  same  liquids,  ether  being  used 
in  addition.    Most  of  the  residues  were  crystalline. 
In  order  to  obtain  a  larger  quantity  of  the  crystals  75  grams  of  the 
drug  were  treated  with  95  per  cent,  alcohol.  This  tincture  was  evapo- 
rated to  a  small  bulk  and  precipitated  with  water.  The  filtrate  obtained 
was  shaken  with  petroleum,  benzol  and  chloroform.  The  residue  from 
the  petroleum  was  entirely  soluble  in  aqueous  sodium  hydrate  solution, 
and  after  neutralization  with  hydrochloric  acid  a  precipitate  of  a 
brownish  color  formed.  The  aqueous  solution  was  then  acidified  and 
shaken  with  the  liquids  mentioned  above.  The  residues  from  benzol 
and  chloroform  had  a  bitter  taste,  a  neutral  reaction  and  a  crystalline 
structure.  The  same  crystals  were  also  found  after  the  acidified  aqueous 
liquid  had  been  made  alkaline  and  at  that  place  the  reactions  are  also 
given. 
The  precipitate  obtained  from  the  alcohol  was  boiled  with  dilute 
acid  and  this  liquid  shaken  as  above,  and  also  after  it  was  made  alka- 
line.   The  residues  consisted  of  a  yellow  resin  neutral  to  test  paper. 
The  undissolved  precipitate  from  above  was  boiled  with  potassium 
hydrate  solution  and  this  shaken  with  the  same  liquids  noticed  above. 
The  residue  from  the  petroleum  shaking  consisted  of  a  soft  resinous 
mass  and  of  colorless  crystalline  plates,  the  whole  having  the  odor  of 
orris  root.    The  crystals  were  freed  from  adhering  resin  by  a  few
