rich,  bright  red  liquid,  possessing  the  virtues  of  the  berries  in  a  marked 
degree.    The  glycerin  is  a  good  solvent  for  the  tannic  acid,  and  the 
malic  acid  present  rapidly  dissolves  in  the  menstruum. 
The  formula  is  as  follows  : 
Take  of  sumach  berries  in  moderately  fine  powder  sixteen  troy 
ounces. 
Glycerin,  four  fluid-ounces. 
Water, 
J'  }  each  a  sufficient  quantity. 
Mix  half  a  pint  of  alcohol,  three  fluid-ounces  glycerin  and  five  fluid- 
ounces  of  water,  and,  having  moistened  the  sumach  with  four  fluid- 
ounces  of  the  mixture,  pack  in  a  suitable  percolator  (Squibb's  new 
percolator  answers  very  well),  pour  on  top  the  remaining  portion  of 
the  sixteen  fluid-ounces  of  menstruum  ;  close  the  percolator  and  allow 
the  powder  to  macerate  for  four  days ;  then  open  the  percolator  and 
continue  the  percolation  until  twenty-four  fluid-ounces  have  been  ob- 
tained. Of  these,  reserve  the  first  fourteen  fluid-ounces,  and  evapo- 
rate the  remainder  to  two  fluid-ounces,  mix  with  the  reserved  portion 
and  filter,  if  necessary. 
Like  many  other  fluid  extracts  containing  glycerin,  a  slight  pre- 
cipitation of  coloring  and  extractive  matter  takes  place  when  diluted 
with  water.  If  considered  desirable,  the  precipitation  may  be  mixed 
with  an  equal  quantity  of  water,  and  re-evaporated  at  a  low  tempera- 
ture ;  but,  as  probably  all  of  the  prescriptions  into  which  it  would  en- 
ter would  require  filtration,  it  is  unnecessary. 
A  very  good  gargle  and  mouth  wash  may  be  made  by  taking —

Almost  every  apothecary  has  more  or  less  demand  for  a  prepara- 
tion of  this  kind,  and  many  may  wish  to  include  some  appliance  of 
this  character  among  their  specialties. 
Having  what  I  consider  a  most  excellent  formula  for  such  a  pre-
