The  drug  was  then  treated  with  stronger  ether,  which  dissolved  four 
per  cent.  The  dry  extract  was  treated  with  boiling  distilled  water 
and  lost  three-tenths  of  one  per  cent.  It  gave  a  bitter  taste  to  the 
water,  but  yielded  no  precipitate  to  tests  for  alkaloids.  On  evaporat- 
ing the  ether  there  were  formed  some  fine  needle-shaped  crystals. 
The  extract  was  dissolved  in  alcohol,  the  chlorophyll  removed  by 
animal  charcoal,  and  several  attempts  were  made  to  obtain  the  crys- 
tals in  a  purer  state,  but  without  success.  There  was,  however,  a 
resin  present  that  had  a  tendency  to  crystallize. 
Absolute  alcohol  was  the  next  menstruum  used,  and  the  extract  ob- 
tained was  five  per  cent,  of  the  drug.  About  one  and  a  half  per  cent, 
was  soluble  in  water.  The  portion  that  did  not  dissolve  in  water  was 
a  greenish-yellow  powder  and  had  a  lasting  unpleasant  taste.  Tan- 
nin was  found  in  the  soluble  portion,  but  the  percentage  was  not  de- 
termined. The  aqueous  solution  was  made  acid  and  agitated  success- 
ively with  petroleum,  benzol  and  chloroform.  It  was  then  made  al- 
kaline and  the  same  treatment  repeated.  The  resulting  liquids  were 
evaporated,  but  nothing  found  in  the  petroleum  or  benzol.  There 
was  a  deposit  of  crystals,  however,  from  both  the  acid  and  alkaline 
liquid  with  chloroform.  Nothing  else  of  importance  was  found  in 
the  alcoholic  extract. 
The  residue,  after  exhaustion  with  alcohol,  was  macerated  with 
water,  which  dissolved  thirteen  per  cent,  of  the  drug,  containing  mu- 
cilage, coloring  matter  and  ash,  but  no  sugar,  nor  anything  else  of  spe- 
cial importance. 
The  residue  insoluble  in  water  yielded  to  solution  of  caustic  soda 
mucilaginous  substances  and  albuminoids  amounting  to  four  per 
cent. 
Diluted  hydrochloric  acid  dissolved  two  per  cent,  of  the  drug,  and 
of  this  six-tenths  of  one  per  cent,  was  oxalate  of  calcium.  No  starch 
was  found. 
On  treatment  with  chlorine  water  the  loss  was  six  per  cent,  lignin  ; 
and  with  chlorate  of  potassium  and  nitric  acid  the  loss  was  two  per 
cent. 
Three  pounds  of  the  fresh  drug  were  distilled  with  water.  From 
the  distillate,  by  shaking  with  ether,  was  obtained  a  volatile  oil  of  a 
bright  green  color  with  a  penetrating  odor,  resembling  that  of  fennel 
or  anise,  but  more  pleasant.  The  yield  was  very  small,  about  one 
drachm  being  obtained  from  the  three  pounds.    While  the  solution  of
