oxide  of  iron.  Formiate  of  beeberine  was  not  crystallizable,  but 
formed  in  shining  brown  scales,  soluble  in  alcohol ;  less  so  in  ether 
and  water.  Formiates  of  baryta  and  strontia  (made  by  dissolving 
the  carbonates  in  the  acid)  were  obtained  in  beautiful  lustrous 
crystals,  were  not  altered  by  contact  with  the  air,  and  were  quite 
soluble  in  water.  Formiate  of  copper  (made  by  dissolving  the 
carbonate  in  the  acid)  formed  in  light  blue  crystals,  quite  soluble 
in  water.  Formiate  of  cobalt,  made  as  above,  formed  in  fine 
rose  colored  crystals,  quite  soluble  in  water.  Formiate  of  nickel 
is  said  to  be  crystallizable,  but  in  many  trials  I  was  not  able  to 
obtain  it  in  crystals.  Formiate  of  uranium  (made  by  dissolving 
the  yellow  oxide  in  the  acid)  was  obtained  in  fine  yellow  crystals. 
The  above  experiments  were  made,  more  with  a  view  to  the 
interest  they  afforded  to  myself,  than  with  the  expectation  of 
eliminating  any  thing  new  in  regard  to  the  subject. 
ON  FLUID  EXTRACT  OF  SANGUINARIA. 
By  Samuel  Campbell. 
Having  been  requested  by  a  physician  to  make  a  preparation 
of  Sanguinaria,  containing  all  the  active  principles,  in  a  concen- 
trated form,  (to  my  knowledge  no  formula  for  a  fluid  extract 
has  yet  been  published*),  I  have  devised  one,  and  offer  the  fol- 
lowing process  : 
Take  of  Sanguinaria  Canadensis,       .       .        8  oz. 
Acetic  Acid,  No.  8,  .       .        2  oz. 
Water,       .        .       .        .  10  oz. 
Sugar,       .        .       .  .        8  oz. 
Diluted  Alcohol,  .  .  .  q.  s. 
Having  reduced  the  root  to  a  coarse  powder,  I  then  incorpo- 
rated it  with  the  acetic  acid,  previously  mixed  with  the  water* 
After  allowing  it  to  macerate  for  forty-eight  hours,  it  was  trans- 
ferred to  a  glass  percolator,  and  exhausted  by  means  of  diluted 
alcohol.  By  means  of  a  water  bath  the  tincture  was  evaporated 
to  twelve  fluid  ounces,  the  sugar  added,  and,  when  dissolved, 
strained. 
[*  A  formula  for  an  acetic  syrup  of  Sanguinaria  was  published  in  this  Journal 
page  108,  Vol.  2nd,  3rd  series,  (1854),  by  T.  S.  Wiegand— of  the  strength  of 
four  ounces  to  the  pint. — Editor.]
