416  GLEANINGS  FROM  THE  FRENCH  JOURNALS. 
Roman  Chamomile. — M.  Trimbal  Lagrave,  of  Toulouse,  (Rep. 
de  Pharm.  Avril,  1859)  states  that  he  has  found  this  drug  in 
French  commerce  adulterated  with  the  flowers  of  Crysanthemum 
parthenium,  Pers.,  and  those  of  Matricara  parthenoides,  Derf. 
Elixir  of  Citro-  Lactate  of  Iron. — M.  Robineaud,  {Jour,  de 
Rharmacie,)  gives  the  following  recipe  for  this  preparation  ; 
Take  of  Citrate  of  the  protoxide  of  iron,  half  a  drachm. 
Lactate  of  the  protoxide  of  iron,  half  a  drachm. 
Distilled  water,  nineteen  fluid  drachms. 
Alcohol  (80  p.  ct.)  fourteen  fluid  drachms. 
Simple  syrup,  twenty  fluid  drachms. 
Tincture  of  lemon  peel, 
Tincture  of  cinnamon,  each  half  a  fluid  drachm. 
Tincture  of  cloves,  six  drops. 
Caramel,  q.  s. 
Put  the  lactate  of  iron  in  powder  in  a  capsule  with  the  distilled 
water,  heat  gently  till  dissolved,  add  the  proto-citrate  of  iron, 
which  dissolves  promptly,  filter  the  solution  into  a  bottle  contain- 
ing previously  the  syrup  and  alcohol,  and  lastly,  add  the  tinctures 
and  caramel. 
On  the  Essence  of  Scurvy  Grass,  (Cochlearia  officinalis)  by  M. 
Geiseler,  (Arch,  der  R harm,  and  Jour,  de  Rharm.  July,  1859.) 
The  leaves  of  scurvy  grass  contain  of  organic  matter  6.23  per 
cent,  ashes  1.57  per  cent ;  and  of  water  92.19  per  cent.  The 
essential  oil  which  these  leaves  afford  by  distillation  with  water- 
does  not  pre-exist  in  the  plant,  but  is  produced  under  the  influ- 
ence of  water  and  a  peculiar  ferment.  According  to  M.  Simons 
the  dried  leaves  do  not  afford  the  oil  unless  bruised  white 
mustard  seeds  are  admixed  with  them  to  furnish  the  ferment. 
The  younger  leaves  afford  more  oil  than  the  old,  about  l-5000th. 
The  seeds  of  the  plant  also  yield  the  oil. 
Essence  of  scurvy  grass  has  heretofore  been  considered  to  be 
identical  with  oil  of  mustard,  but  M.  Geiseler  finds  it  to  be 
C6H50,S  ;  that  is  to  say,  oil  of  garlic  plus  one  atom  of  oxygen. 
Essence  of  scurvy  grass  is  very  volatile,  its  odor  recalls  at  the 
s&me  time  ether  and  horseradish,  its  density  is  0.942,  slightly 
soluble  in  water  and  very  soluble  in  alcohol. 
Mixed  with  six  or  eight  times,  its  volume  of  concentrated
