  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Pyrrol  \Pyr"rol\,  n.  [Gr.  ?  flame-colored  (from  ?  fire)  +  L. 
  oleum  oil.]  (Chem.) 
  A  nitrogenous  base  found  in  coal  tar,  bone  oil,  and  other 
  distillates  of  organic  substances,  and  also  produced 
  synthetically  as  a  colorless  liquid,  {C4H5N},  having  on  odor 
  like  that  of  chloroform.  It  is  the  nucleus  and  origin  of  a 
  large  number  of  derivatives.  So  called  because  it  colors  a 
  splinter  of  wood  moistened  with  hydrochloric  acid  a  deep  red.
