Others  being  soft  and  presenting  a  swollen  appearance  (Figs.  26,  31); 
the  former  were  sometimes  small,  the  latter  of  large  size,  as  the 
sketches  indicate.  Hyaline  casts  (Figs.  25,  26)  were  much  less 
frequent  than  granular  casts.  Casts  containing  one  or  more  mu  Ici 
(Figs.  25,  30,  31),  and  epithelial  casts  (Figs.  27,  30,  31),  were  not 
uncommon.  Free  cells  and  cell  masses  were  also  seen  (Figs.  2;, 
30,  31);  the  cells  were  mononuclear,  of  spheroidal  aspect,  with  some¬ 
times  moderate,  sometimes  abundant,  cytoplasm,  and  obviously  came 
from  the  uriniferous  tubules.  Red  blood  cells,  which  were  not  met 
with  in  the  rabbit’s  urine  during  experimental  haemoglobinuria,  were

out  of  the  twenty  attacks  investigated  (Tables  40  and  43  ;  Figs.  23,
