epithelial  cells,  both  presumably  of  renal  origin  and  apparently 
separated  off  from  the  casts,  were  met  with,  as  also  red  cells  in 
small  numbers  in  both  Case  /a  (Fig.  32)  and  Case  ii.  Casts  and 
red  blood  cells  continued  in  the  urine  during  the  whole  period  inter¬ 
vening  between  cessation  of  haemoglobinuria  and  death.  No 
bacteria  or  other  formed  elements  were  met  with  ;  hyaline  casts  were 
absent.  The  amount  of  the  deposit,  which  could  not  be  accurately 
measured,  owing  to  the  small  amount  of  urine  passed,  but  w-as 
relatively  as  well  as  actually  extremely  small,  did  not  appear  to  vary 
much  from  day  to  day  during  the  period  of  suppression,  nor  did  the 
composition  of  the  deposit  show  any  marked  change  during  this 
period.

It  will  be  noticed  that  the  chief  alteration  in  the  appearance  of 
the  casts  observed  during  suppression  of  urine  consisted  in  their 
large  size,  in  the  coarseness  of  the  granules  they  contained,  and  in 
the  frequent  presence  of  an  external  epithelial  envelope.
