If  a  person  honestly  believes,  or  has  reason  to  believe  at
the  time  of  the  shooting,  that  he  is  in  great  peril  and  great
bodily  harm  is  about  to  be  inflicted  upon  him,  he  has  a  right  to
act  under  such  well  grounded  apprehension.  The  danger  need
not  in  fact  exist.  State  v.  Praunhurg,  40  Iowa  555;  State  v.
Abarr,  39  Iowa  185 ;  State  v.  Collins,  32  Iowa  36.
Neither  court  nor  jury  can  apply  the  doctrine  of  ordinary
prudence  without  having  in  mind  the  knowledge,  conditions,
and  circumstances  of  the  party  called  upon  to  act.  The  defend-
ant in  this  case  requested  an  instruction  on  self-defense  relative
to  the  threats  made  by  the  deceased  against  the  defendant  which
were  directly  heard  by  the  defendant  or  communicated  to  him.
