mono-  in  place  of  a  dichloracetanilide,  by  the  action  of  anilin  acetate  upon  chlor- 
acetylcyanide,  which  was  observed  by  Pinner,  may  be  referred  to  a  reduction  by 
means  of  hydrogen  which  has  been  liberated  from  water  formed  in  the  course  of 
the  reaction. — Jour.  Chem.  Soc.  [Lond."|,  April,  1878,  from  Deut.  Chem.  Ges.  Ber.,

A  Process  for  Preparing  Formic  Acid.  By  V.  Merz  and  J.  Tibiriga. — Sodium 
formate  can  be  prepared  by  passing  a  stream  of  carbon  monoxide  over  soda-lime 
heated  in  an  oil-bath  to  a  temperature  between  2000  and  25o°C.  The  absorption  of 
carbon  monoxide  by  soda-lime  may  be  used  as  a  lecture  experiment  to  demonstrate 
the  formation  of  organic  compounds  from  inorganic  materials,  and  it  might  be 
employed  for  manufacturing  formic  acid  should  a  large  demand  for  this  acid  ever 
arise. — Ibid.,  from  Ibid.,  x,  21 17. 
Action  of  Alcoholic  Potassa  on  Chloroform.  By  M.  Berthelot. — By  acting  on 
a  solution  of  chloroform  in  absolute  alcohol,  with  alcoholic  potassa,  the  author  has 
obtained  results  which  show  that  for  the  complete  decomposition  of  1  equivalent  of 
chloroform,  between  2  and  3  equivalents  of  potassa  are  sufficient,  instead  of  4  equiv- 
alents, as  required  by  theory.  From  this  and  from  the  fact  that  a  portion  of  the 
chlorine  does  not  enter  into  combination  with  the  potassium,  he  thinks  it  probable 
that  a  tribasic  formic  ether  is  produced,  together  with  a  chlorinated  compound. —

Juglone  (Nucin).  By  C.  Reischauer. — This  body,  prepared  from  the  green 
shells  of  walnuts  (Juglatts  regia),  has  been  analyzed  by  the  author,  who  assigns  to 
it  the  empirical  formula  C36H12O10. 
A  compound  of  this  body  with  copper  is  obtained  by  adding  its  alcoholic  solu- 
tion to  a  solution  of  neutral  cupric  acetate  either  in  water  or  alcohol.  It  occurs 
in  small  bronze-colored  shining  crystals,  and  after  drying  at  ioo°  contains  15*83 
per  cent.  Cu.  Sufficient  data  are  not  yet  at  hand  for  the  determination  of  the  con- 
stitution of  these  compounds. 
This  paper  also  contains  details  of  certain  modifications  of  the  ordinary  method 
of  combustion  which  had  to  be  adopted  in  the  analyzis  of  juglone,  in  consequence 
of  its  volatility. — Ibid.,  March,  1878,  from  Deut.  Chem.  Ges.  Ber.,  x,  1542 — 1548. 
Chemical  Compounds  contained  in  Liquid  Storax.  By  Wilhelm  v.  Miller. — 
The  results  of  the  author's  researches  contained  in  the  second  part  of  the  paper 
(too  long  for  abstraction)  show  that,  in  addition  to  styrolene,  cinnamic  acid  and 
styracin,  storax  contains — 
(1.)  Phenylpropyl  cinnamate  in  considerable  quantities. 
(2.)  Ethyl  cinnamate  in  small  quantities. 
(3.)  A  body  which  smells  like  'vanillin,  and  forms  a  crystalline  compound  with 
sodium  bisulphite.  This  body  melts  at  650,  and  may  possibly  be  ethylvanillin.  It 
-occurs  in  small  quantities.
