there  throughout  the  cortex.  I  he  above  two  changes — the  enlarge¬ 
ment  of  the  kidney  and  the  distribution  of  the  dark  brown  medullary 
striation  and  cortical  stippling — are  shown  somewhat  diagram- 
matically  in  Fig.  6i,  C.  Recent  haemorrhages  of  a  punctate 
character  were  seen  in  Case  /a  in  the  mucous  membrane  of  the  renal 
pelvis,  as  well  as  an  ecchymosis  about  i  cm.  in  diameter  beneath  the 
capsule  of  the  left  kidney.

days  after  haemoglobinuria  had  ceased.  Bfackwater  Fever,  Case  7a. 
A  dilated  convoluted  tubule  is  seen  in  transverse  section.  The  lumen 
ot  the  tubule  IS  partly  occupied  by  irregular  masses,  composed  of 
darkly  stained  granules.  The  individual  granules,  when  discrete, 
lange  from  2^  or  3/r  to  571  m  diameter.  To  the  right  some  finely 
granular  debris  is  seen.  Within  the  lumen  of  the  tubule  are  two  free 
epithelial  cells  the  nuclei  of  which  are  indistinct.  The  epithelium 
of  he  waU  of  the  tubule  is  flattened,  but  does  not  present  any 
marked  evidence  of  degeneration.  Hardened  in  alcohol.  Stained  with 
iron  alum  haematoxylin.  x  1350. 
On  making  sections  of  the  kidneys  in  Cases  ya  and  ii,  it  was 
found  (Figs.  34,  36,  38,  40,  54  and  56)*  that  many,  but  not  all,  of  the 
-  Figs.  53-60  are  opposite  p.  131  (Plates  1  and  2).
