completely  detached  (Fig.  44).  Some  of  the  tubules,  in  particular 
the  large  collecting  tubules,  exhibited  no  epithelial  covering,  the  ' 
basement  membrane  being  bare  (Fig.  42).  Lightly  staining  material,  | 
present  in  the  form  of  granules,  rs/^  to  o'5/“  in  diameter,  and  of 
flocciilent  deposit,  is  seen  in  Figs.  43  and  58.  The  lumen  of  the 
Fig.  46.  Another  section  of  cortex  of  kidney  during  experimental  haemo- 
globinuria  of  Rabbit  7,  Table  35.  The  epithelium  is  healthy  in  aspect, 
showing  no  sign  of  cloudy  swelling  or  other  indication  of  degeneration, 
i’he  tubules  are  not  recognisabljf  dilated,  but  casts  of  granular 
material,  stained  ver)’  darkly,  are  present  in  six  of  the  tubules.  Casts 
presenting  a  homogeneous  aspect,  indicated  in  the  sketch  by  parallel 
shading,  are  seen  in  five  tubules.  There  is  no  increase  of  nuclei  or 
other  change  in  the  interstitial  substance  of  the  kidney.  A  few  of  the 
blood  capillaries  contain  red  cells,  stained  black.  No  malarial 
pigment  is  seen.  Fixed  in  Flemming's  solution.  Stained  with  iron 
alum  haematoxylin.  x  155.
