C. ;  the  same  was  also  found  in  the  capsules.  The  crystals  were  insolu- 
ble in  alcohol  and  ether,  but  soluble  in  chloroform,  and  were  neutral 
to  test  paper. 
2.  Ether  maceration. — The  powder  was  next  treated  with  the  neces- 
sary amount  of  ether.  The  extract  amounted  to  0'G6  per  cent.,  and 
consisted  of  resin. 
3.  Absolute  alcohol  treatment. — The  powder  was  next  treated  wiih 
the  requisite  quantity  of  absolute  alcohol.  The  soluble  portion 
amounted  to  12  2  per  cent.  The  dry  extract  was  soluble,  as  follows  : 
7*625  per  cent,  in  water,  4*275  per  cent,  in  dilute  ammonia,  and  0'3 
per  cent,  insoluble  in  either.  The  aqueous  solution  contained  tannin 
amounting  to  5*4  per  cent.  The  dilute  ammonia  dissolved  the  resin, 
which  was  of  a  ruby-red  color  and  precipitable  by  neutralization  with 
acetic  acid. 
4.  Aqueous  extraction. — The  powder  insoluble  in  the  foregoing  was 
treated  with  the  necessary  quantity  of  water.  This  mixture  was 
diluted  on  account  of  the  mucilage  present  and  filtered.  Alcohol  gave 
a  precipitate  which  amounted  to  4  per  cent.,  and  on  condensation 
alcohol  precipitated  3  per  cent.  more.  The  total  extract  amounted  to 
8*96  per  cent. 
5.  Maceration  with  diluted  alkali. — The  powder  was  next  macerated 
with  a  0*2  per  cent,  solution  of  sodium  hydrate.  The  total  extract 
amounted  to  10'510  per  cent.,  of  Avhich  9*605  percent,  was  precipitated 
by  alcohol  and  acetic  acid  to  neutralization. 
6.  Treatment  with  diluted  acid. — The  powder  insoluble  in  the  fore- 
going extractions  was  treated  with  diluted  2  per  cent,  hydrochloric 
acid.  The  soluble  portion  amounted  to  8  per  cent.  The  remaining 
insoluble  powder  amounted  to  42*625  per  cent. 
Capsules. — The  moisture  in  the  capsules  amounted  to  10*833  per 
cent,  and  the  ash  to  3*5  per  cent.  The  solubilities  of  the  ash  were  as 
follows : 
Soluble  in  water  2-333 
Soluble  in  hydrochloric  acid   -    '467 
Insoluble  in  either  700 
  3 '500  per  cent. 
The  qualitative  analysis  resulted  as  follows:    i\cids:  sulphuric  and 
phosphoric;  Bases:  copper,  magnesium,  iron,  aluminium,  potassium, 
sodium. 
1 .  Petroleum  treatment. — The  powder  was  exhausted  with  petroleum. 
The  soluble  portion  amounted  to  1*25  per  cent.;  0*5  per  cent,  was 
volatile  oil  and  0*75  per  cent,  was  wax  and  a  crystalline  principle.
