Sugar,  .  .  .  17  oz.  av.

Place  the  iodine,  three  ounces  of  distilled  water,  and  the  iron  wire 
cut  into  small  pieces,  in  a  thin  glass  flask  or  a  porcelain  dish,  shake 
or  stir  occasionally  until  the  reaction  ceases,  and  the  solution  has  ac- 
quired a  clear  greenish  color,  without  a  tinge  of  yellow.  Having  in- 
troduced the  sugar  into  a  porcelain  dish,  filter  the  solution  of  iodide 
of  iron  upon  it.  Wash  the  filter  by  pouring  into  it  two  ounces  of  dis- 
tilled water,  allowing  the  same  to  filter  into  the  sugar.  Dissolve  the 
sulphate  of  manganese  and  iodide  of  potassium  separately  in  one-half 
an  ounce  of  cold  distilled  water  by  trituration  in  a  mortar ;  mix  the 
two  solutions  together  and  allow  the  sulphate  of  potash  to  precipitate, 
then  carefully  remove  the  mixture  into  a  moistened  filter-paper  within 
a  glass  funnel,  and  allow  the  solution  of  iodide  of  manganese  to  filter 
upon  the  sugar.  When  well  drained  wash  the  precipitate  within  the 
funnel  with  one-half  an  ounce  of  cold  distilled  water,  allowing  it  to 
filter  into  the  sugar. 
Finally,  finish  the  operation  by  adding  to  the  above  enough  dis- 
tilled water  to  make  the  whole  measure  twenty  fluid  ounces  ;  stir  oc- 
casionally until  dissolved,  and  filter.

FLUID  EXTRACT  OF  SUMACH  BERRIES. 
By  Joseph  P.  Remii\gton. 
Read  before  the  Pharmaceutical  Meeting,  Dec.  16,  1873. 
In  some  sections  of  this  city,  this  valuable  preparation  is  duly  ap- 
preciated, being  largely  prescribed  as  an  ingredient  in  mouth  washes 
and  gargles,  where  the  astringent  and  pleasantly  acid  properties  of 
sumach  berries  would  be  indicated. 
Not  having  a  satisfactory  formula  for  the  preparation  of  the  fluid 
extract,  it  occurred  to  the  writer  to  try  the  Pharmacopoeia  process  for 
the  astringent  fluid  extracts,  and  the  result  you  have  before  you,  a
