ON  ANEMONE  LUDOVICIANA. 
Take  of  Iodine  two  troy  ounces, 
Iron  filings  one    "  " 
Simple  syrup  sixteen  fluid  ounces,  or  q.  s. 
Distilled  water  a  sufficient  quantity. 
Mix  the  iodine  with  three  fluid  ounces  of  water  in  a  glass  flask,  and 
gradually  add  the  iron  filings,  with  agitation,  and  shake  until  all  the  iodine 
has  combined.  Place  the  syrup  in  a  capsule,  heat  it  to  the  boiling 
point,  and  filter  into  it  the  concentrated  solution  of  iodide  of  iron,  then 
having  washed  the  filter  with  a  little  boiling  distilled  water,  complete  the 
measure  of  20  fluid  ounces  if  necessary  with  simple  syrup  and  mix. 
ON  ANEMONE  LUDOVICIANA.

Polyandria  Polygynia,  Linnaeus. 
Ranunculacese,  Jussieu. 
Scape  1-flowered,  involucrate,  involucrum  softly  lanuginous, 
subulately  divided ;  leaves  digitate,  multifid,  upper  surface 
smooth,  segments  entire,  linear,  acute  ;  petals  6,  oblong-ovate, 
erect. — JYuttall. 
The  above  plant,  which  Nuttall  states  to  be  found  near  the 
confluence  of  the  Missouri  and  Platte  rivers,  and  thence  west  to 
the  Rocky  Mountains,  is  also  met  with  in  considerable  abun- 
dance in  the  State  of  Minnesota,  especially  on  the  dry,  sandy 
bluffs  forming  the  bed  of  the  Mississippi. 
The  large,  cup-shaped  flowers  are  of  a  pale,  purple  hue,  and 
appear  before  the  leaves  almost  immediately  after  the  melting 
of  the  snow  has  shown  that  the  long  and  dreary  winter  of  the 
North  is  approaching  its  close.  Hence  these  blossoms  are 
eagerly  sought  for  as  the  first  offerings  of  the  long  desired 
spring. 
The  many  points  of  similitude  between  this  plant  and  the 
European  Anemone  Pulsatilla,  which  were  also  noticed  hj 
Nuttall,  very  naturally  gave  origin  to  the  supposition,  that  in 
chemical  composition,  and  therapeutical  effects  they  were  also 
closely  allied,  if  not  synonymous.  Numerous  experiments,  in- 
stituted by  Dr.  W.  H.  Miller,  of  St.  Paul,  Minnesota,  with  a 
view  of  verifying  the  latter  surmise,  proved  to  be  entirely  suc- 
cessful, and  also  served  to  establish  the  value  of  this  remedy  in
