or  four  (lays  after  the  disappearance  of  haemoglobinuria,  except  in 
Cases  /a  and  ii,  in  vvhicli  suppression  of  urine  occurred;  in  these 
casts  or  plugs  continued  for  eight  and  five  days  respectively,  until 
death  occurred. 
Occasionally  squamous  epithelial  cells  were  met  with,  and 
sometimes  also  pus  cells  (Cases  2  and  g),  the  latter  persisting  after 
complete  recovery  from  black  water  fever.  .Short  bacilli  were  present 
in  one  case  (Case  2),  both  before  and  after  the  attack.  In  no  other 
case  were  bacteria  seen,  and  in  no  case  were  organisms  or  cells 
other  than  those  already  described  met  with.
