a.  Pleas  to  Supplemental  Bills,  —  Where  no  right  exists  in  the
plaintiff  to  file  a  supplemental  bill,  or  the  matter  of  the  supple-
mental bill  might  have  been  inserted  into  the  original  bill  by  way
of  amendment  thereto,  as  where  it  did  not  arise  subsequent  to
filing  the  original  bill ;  or  if  matter  is  inserted  into  the  original
bill  by  way  of  amendment,  which  ought  properly  to  have  been
matter  for  a  supplemental  bill,  as  where  it  arose  subsequent  to  the
original  bill,  these,  when  the  matter  cannot  be  reached  by  a
demurrer,  is  ground  for  a  plea.»

b.  Pleas  to  Bills  of  Revivor.  —  Where  the  plaintiff  has  no  right
in  himself  to  revive  the  suit  at  all,  or  there  is  no  sufficient  cause
to  revive,  or  if  the  legal  representative  or  person  entitled  to  re-
vive is  barred  by  the  statute  of  limitations,  or  where  there  is  a
want  of  proper  parties,  or  the  bill  is  wrongly  filed  in  place  of  some
other  bill,  these  may  all  be  availed  of  by  the  defendant  by  way  of
plea  or  demurrer ;  and  in  those  cases  where  a  demurrer  will  not  he,
a  plea  is  proper.*

7.  Pleas  to  Other  Bills  in  the  nature  of  original  bills.
