ceding;  dissolves  more  slowly  in  water,  of  which  it  requires 
twice  its  weight  for  solution,  with  a  residue  of  4*7  per  cent.  Di- 
luted with  1000  parts  of  water  its  taste  and  color  are  less  marked 
than  the  first  extract,  and  its  strong  aqueous  solution,  treated  with 
alcohol  27-8  per  cent.,  was  precipitated. 
3.  The  third  extract,  by  steam,  obtained  from  the  woody  resi- 
due of  the  two  preceding  extracts  having  been  removed,  amounted 
to  16  per  cent.  It  was  dry,  hard,  friable  and  nearly  pulveru- 
lent. Its  taste  is  sweet,  without  acrimony,  and  remains  a  long 
time  in  the  mouth  without  dissolving.  Put  in  cold  water  a  por- 
tion dissolves,  and  an  abundance  of  insoluble  matter  floats  on  the 
solution,  amounting  to  57  per  cent.  Dissolved  in  1000  parts  of 
water  the  solution  has  no  characteristics  of  liquorice,  and  a  solu- 
tion of  the  soluble  matter  yields  184  per  cent,  when  precipitated 
with  alcohol. 
4.  Liquorice  root  treated  by  M.  De'londre's  method,  yields 
from  42  to  45  per  cent,  of  extract  fin  rolls.  The  extract  is  a 
shining  black,  smooth  fracture,  firm  consistence,  not  softened 
when  exposed  to  the  air,  and  similar  in  its  general  relations  to 
the  best  extract  of  commerce.  Its  taste  is  more  decided,  due  to 
its  greater  purity.  Dissolved  in  1000  parts  of  water,  a  sweet 
colored  solution  is  afforded,  and  alcohol  precipitates  from  its  con- 
centrated solution  27.4  per  cent,  of  matter. 
The  committee  conclude  their  remarks  by  a  favorable  opinion 
of  the  process  of  M.  Delondre,  believing  that  it  is  necessary,  in 
order  to  have  a  permanent  extract  to  retain  in  it  the  insoluble 
matter  taken  up  by  the  steam,  however  desirable  it  may  be  for 
pharmaceutical  purposes  to  employ  the  pure  soluble  extract  ob- 
tained by  infusion. 
ON  PENGHAWAR  DJAMBI,  A  NEW  STYPTIC. 
By  Daniel  Hanbury. 
A  small  package  of  the  curious  drug,  known  by  the  name  of 
Penghawar  Djambi,  or  by  the  not  less  barbarous  designation 
Pakoe  Kidang,  was  lately  offered  at  one  of  the  public  drug  sales 
in  the  city. 
The  drug  consists  of  the  lower  part  of  the  stalk  or  stipes  of  a 
large  fern,  native  of  the  island  of  Sumatra.    The  stalks  as  im-
