time  began  to  decompose  and  deposite  iodine,  generating  at  the 
same  time  oxygen  and  hydrochloric  acid. 
Grtineberg  obtained  in  this  manner  18  ounces  of  iodine. 
In  order  to  obtain  the  bromine,  the  liquid  from  which  the  iodide 
of  copper  had  been  precipitated  was  filtered,  evaporated  to  the 
consistence  of  a  syrup  mixed  with  oxide  of  manganese  and  sulphu- 
ric acid,  distilled,  and  the  products  of  distillation  led  into  a  solu- 
tion of  caustic  potash.  The  bromine  obtained  amounted  to  some- 
what more  than  half  an  ounce.

New  Alkaloids. — How  has  studied  the  action  of  the  iodids  of  methyl, 
ethyl  and  amyl  upon  morphine  and  codein.  When  finely  pulverized  mor- 
phine is  digested  in  a  closed  tube  with  an  alcoholic  solution  of  iodid  of 
ethyl,  a  white  crystalline  substance  separates,  which,  after  recrystallization, 
is  obtained  in  fine  white  needles.  These  are  the  iodid  of  ethyl-morphin, 
the  formula  of  which  is  C34H18  (C4H5)  N06-j-HI.  The  base  was  isolated 
by  treating  the  iodid  with  oxyd  of  silver,  and  appeared  as  a  very  caustic 
liquid  of  a  reddish  brown  color;  which  gave  no  crystals  on  evaporation, 
but  only  a  semi-transparent  dark  colored  mass  which  was  deposited  from  a 
boiling  solution  in  alcohol  as  a  boiling  in  alcohol  as  a  microscopic  crystal- 
line mass.  This  powder  is  readily  dissolved  in  muriatic  acid  to  a  yellow 
solution,  which  gives  heavy  yellow  precipitates  with  chlorid  of  platinum 
and  bichromate  of  potash.  The  oxyd  is  readily  soluble  in  water  ;  its  pro- 
bable formula  is  C34H18  (C4H5)  N06.  With  iodid  of  methyl  a  similar  base 
was  produced,  the  iodid  of  which  has  the  formula  C34H]8  (C2H3)  N06-f-HJ  ; 
the  author  terms  it  methyl-morphin.  When  morphin  is  heated  with  chlorid 
of  amyl,  fusel  oil  and  chlorid  of  morphin.ammonium  are  produced.  Codein 
digested  with  iodid  of  ethyl  yields  a  highly  crystalline  colorless  substance 
which  is  the  iodid  of  ethyl-codein-ammonium,  and  which  has  the  formula 
C36H20  (C4H5)N06-j-HI.  Iodid  of  methyl  yields  a  similar  compound  with 
codein.  Methyl-morphin  is  isomeric  with  codein,  but  differs  from  it  in 
chemical  and  physical  properties. — Journal  fur  prakt.  Ohemie,  lix,  489.
