aluminum  and  manganese  are  rarely  encountered.  Copper  is  not  rare. 
Among  the  non-metals,  sulphur  and  phosphorus  are  nearly  always 
present  in  the  ashes  of  plants. — Pharm.  J.,  1914,  vol.  93,  pp.  126-128. 
The  Stability  of  Cinnamic  Aldehyde.  (Phillips,  H.  Adie.)  — 
It  has  been  contended  that  in  the  distillation  of  the  oil  from  chips 
there  was  a  likelihood  that  some  of  the  cinnamic  aldehyde  was 
oxidized  to  cinnamic  acid.  The  experiments  reported  seem  to  prove 
that  under  the  usual  conditions  prevailing  under  steam  distillation 
cinnamic  aldehyde,  both  pure  and  as  a  constituent  of  cinnamon  oil, 
is  not  appreciably  oxidized. — Pharm.  J.,  1914,  vol.  93,  pp.  129,  130. 
The  Composition  of  Tinctura  Iodi  Decolorata.  (Pratt,  Walter 
R.) — The  finished  tincture  made  according  to  the  directions  of  the 
British  Pharmaceutical  Codex  is  an  alcoholic  solution  of  ammonium 
iodide,  with  excess  of  ammonia  containing  about  0.1  per  cent, 
iodoform  and  in  some  cases  ammonium  iodate,  hydroxylamine,  and 
acetaldehyde. — Pharm.  J.,  1914,  vol.  93,  pp.  130,  131. 
The  Determination  of  Iron  in  the  Presence  of  Phosphoric  Acid. 
(Corfield  and  Pratt.) — The  gravimetric  determination  of  ferric  iron 
in  the  presence  of  even  small  quantities  of  phosphates  gave  results 
which  are  much  too  high  and  are  variable  among  themselves.  Both 
the  idiometric  and  reduction  by  stannous  chloride  volumetric  meth- 
ods give  results  which  are  very  accurate  and  can  be  equally  well 
used  in  the  presence  of  phosphoric  acid.  The  former  method  gives 
results  which  tend  to  be  somewhat  high. — Pharm.  J.,  igi4,  vol.

An  Improved  M ethod  for  the  Administration  of  Extr actum  Filicis 
Maris  Liqnidum.  (Crossley,  Holland  F.  W.) — Oleoresin  of  as- 
pidium  can  best  be  exhibited  in  the  form  of  a  jelly  made  with  gelatin 
and  glycerin,  sweetened  with  saccharin  and  flavored  with  oil  of  cin- 
namon. This  form  of  preparation  is  said  to  be  more  palatable  than 
emulsions  or  capsules,  and  the  bulk  is  reasonable  in  relation  to  the 
dose. — Pharm.  J.,  1914,  vol.  93,  p.  133. 
The  place  of  Carbon  Bisulphide  in  Official  Pharmacy  and  Sug- 
gestion for  its  Further  Use.  (Alcock,  F.  H.) — The  use  of  carbon 
disulphide  is  recommended  as  a  solvent  for  fats  and  as  a  means  for 
ascertaining  the  amount  of  constituents  extractable  from  official  liquid 
preparations,  such  as  liquid  extracts  and  tinctures.  Some  useful 
results  have  been  obtained,  a  number  of  which  are  recorded. —
