DONNa;,  L.  Prep.  1.  (B.  P.)  Take  112  lbs.
of  fresh  leaves  and  tender  branches,  bruise  in
a  stone  mortar  or  other  suitable  apparatus,  and
press  out  the  juice,  heat  it  gradually  to  130°
F.,  separate  the  green  colouring  matter  by  a
calico  filter,  heat  the  strained  liquor  to  200°  F.
to  coagulate  the  albumen,  and  again  filter ;
evaporate  the  filtrate  by  a  water  bath  to  the
consistence  of  a  thin  syrup,  then  add  to  it  the
green  colouring  matter  previously  separated,
and,  stirring  the  whole  together  assiduously,
continue  the  evaporation  at  a  temperature  not
exceeding  140°,  until  the  extract  is  of  a  suit-
able consistence  for  forming  pills. — Dose,  J  to
4  gr.,  gi'adually  increased  to  1  or  2  gr.
2.  (Ph.  E.)  Express  the  juice  from  the
bruised  fresh  plant,  sprinkle  the  '  marc '  with
water,  and  again  apply  pressure;  mix  the  ex-
pressed liquids,  filter  them,  and  evaporate  the

3.  (I?h.  D.)  From  the  leaves,  collected  when
the  plant  begins  to  flower.  The  expressed
juice  is  allowed  to  stand  for  24  hours,  and  the
clear  portion  is  decanted ;  the  sediment  is
placed  on  a  calico  filter,  washed  with  an  equal
bulk  of  cold  water,  and  the  filtrate  mixed  with
the  expressed  juice.  The  mixed  liquid  is  next
heated  in  a  water  bath,  to  coagulate  its  albu-
men, and  after  being  skimmed,  and  filtered
through  flannel  whilst  hot,  the  waslied  sedi-
ment is  added,  and  the  whole  evaporated,  as
before.
