4\ayiii873?M'}        Aromatic  Astringent  Syrups.  205 
The  value  of  kino  as  a  reliable  astringent  has  been  long  and  well 
known;  it  is  frequently  prescribed  during  the  summer  months,  when 
astringents  are  most  in  demand,  and  to  supply  this  demand  the  above 
syrup  forms  an  aromatic  preparation  of  it,  representing  about  five 
grains  of  kino  to  each  fluid-drachm.  The  alcoholic  tincture  is  uncer- 
tain in  its  stability,  unless  sugar  be  added  at  the  time  of  preparation. 
The  syrup,  however,  is  almost  of  equal  strength,  is  stable,  palatable 
and  convenient,  especially  when  a  preparation  free  from  alcohol  is 
desired.

Triturate  the  catechu,  first  with  the  glycerin  and  then  with  the  water 
gradually  added,  and  filter.  To  the  filtered  solution  add  the  sugar, 
and  having  dissolved  it  by  a  gentle  heat,  strain  while  hot. 
This  syrup  is  of  the  same  strength  as  the  alcoholic  tincture  of 
catechu,  U.  S.  Pharmacopoeia,  but  differs  from  it  in  containing  no 
alcohol  or  peculiar  extractive,  which  latter  is  the  cause  of  the  mawk- 
ish taste  in  the  tincture.

Mix  the  aromatic  powders,  and  having  moistened  the  mixture  with 
a  sufficient  quantity  of  diluted  alcohol,  pack  it  firmly  in  a  small  glass 
funnel  arranged  for  percolation,  and  gradually  pour  diluted  alcohol 
upon  it  until  half  of  a  fluid-ounce  of  tincture  is  obtained.  Moisten 
the  geranium  with  a  sufficient  quantity  of  diluted  alcohol,  pack  it 
firmly  in  a  conical  glass  percolator,  and  gradually  pour  diluted  alco- 
hol upon  it,  until  one  pint  of  tincture  has  passed.  Transfer  the  liquid 
to  a  porcelain  vessel,  boil  for  a  few  minutes,  evaporate  by  a  water 
bath  to  four  fluid-ounces,  and  filter.    To  the  filtered  liquid  add  the
