which  is  evaporated.  The  residue  is  again  boiled  with  3000  parts 
of  water,  the  solution  is  then  filtered  and  the  filter  washed  with 
warm  water.  The  liquid  is  allowed  to  rest,  and  the  crystals 
obtained  washed  with  distilled  water,  to  which  _L  of  potash  is 
added;  they  are  then  dried.  500  parts  of  these  crystals  are 
dissolved  in  2500  parts  of  water,  the  solution  filtered  and  diluted 
with  12,500  parts  of  water.  To  this  is  added  a  mixture  of  150 
parts  of  sulphuric  acid  with  4000  parts  of  water.  The  precipi- 
tate formed  is  collected  on  a  filter,  washed  first  with  ordinary 
water,  then  with  distilled  water,  pressed  between  folds  of  blotting 
paper,  dried  at  a  temperature  of  77°  Fahrenheit,  reduced  to 
powder  and  preserved  in  a  black  bottle  removed  from  the  light. 
The  drying  at  a  low  temperature,  and  the  washing  with  distilled 
water,  are  two  important  conditions  whereby  the  preservation  of 
the  product  is  assured. — Chem.  News,  Dec.  31,  1859,  from  Jour,

SYNTHESIS  OF  OXYGENATED  BASES  —ARTIFICIAL  ALKALOIDS 
M.  Wurtz  has  shown  recently  that  oxide  of  ethylen  can  be 
united  directly  with  water,  and  form  monoethylenic  alcohol 
(glycol),  diethylenic  and  triethylenic  alcohol,  according  as  these 
combinations  take  place  between  1,  2,  or  3  atoms  of  oxide  of 
ethylen  and  1  atom  of  water. 
The  same  author  now  makes  known  that  oxide  of  ethylen  will 
unite  with  ammonia  without  elimination  of  water ;  that  is,  all  the 
elements  of  oxide  of  ethylen  combine  with  all  the  elements  of 
ammonia  and  form  oxygenated  bases  remarkable  for  their  ener- 
getic properties.  To  prepare  them,  oxide  of  ethylen  is  added  to 
a  concentrated  solution  of  ammonia,  and  the  mixture  left  to 
itself.  If  care  be  not  taken  the  whole  explodes  with  a  powerful 
detonation,  for  the  reaction  produces  much  heat.  When  the 
experiment  is  conducted  properly  a  syrupy  alkaline  matter  is 
obtained.  This  is  neutralized  with  hydrochloric  acid,  and  the 
solution,  sufficiently  evaporated,  produces  colorless  rhombohe- 
dric  crystals  which  contain

A  solution  of  these  crystals  forms  a  double  salt  with  chloride  of 
platinum.     The  supernatant  liquid,  from  which  the  crystals  in
