  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Cyanogen  \Cy*an"o*gen\  (s?-?n"?-j?n),  n.  [Gr.  ky`anos  a  dark 
  blue  substance  +  -gen:  cf  F.  cyanog[`e]ne.  So  called  because 
  it  produced  blue  dyes.]  (Chem.) 
  A  colorless,  inflammable,  poisonous  gas,  {C2N2},  with  a 
  peach-blossom  odor,  so  called  from  its  tendency  to  form  blue 
  compounds;  obtained  by  heating  ammonium  oxalate,  mercuric 
  cyanide,  etc  It  is  obtained  in  combination,  forming  an 
  alkaline  cyanide  when  nitrogen  or  a  nitrogenous  compound  is 
  strongly  ignited  with  carbon  and  soda  or  potash.  It  conducts 
  itself  like  a  member  of  the  halogen  group  of  elements,  and 
  shows  a  tendency  to  form  complex  compounds.  The  name  is  also 
  applied  to  the  univalent  radical,  {CN}  (the  half  molecule  of 
  cyanogen  proper),  which  was  one  of  the  first  compound 
  radicals  recognized. 
 
  Note:  Cyanogen  is  found  in  the  commercial  substances, 
  potassium  cyanide,  or  prussiate  of  potash,  yellow 
  prussiate  of  potash,  Prussian  blue,  Turnbull's  blue, 
  prussic  acid,  etc
