2nd  day.  Blood  examined  at  g  a.m.  and  again  at  2-15  p.m.  On 
each  occasion  the  plasma  was  found  to  be  of  a  dark  orange  colour, 
with  a  slight  greenish  tint,  containing  about  O' 13  per  cent,  of  dissolved 
haemoglobin.  No  isolysin  present.  No  malarial  parasites  in  blood 
smear. 
3rd  day.  Blood  examined  at  2-30  p.m.  Plasma  of  dark  orange 
colour,  with  slight  greenish  tint.  As  before,  only  excessively  faint 
oxyhaemoglobin  bands  could  be  recognised  in  a  column  18  mm.  high, 
the  amount  of  dissolved  haemoglobin  being  about  o' 13  per  cent.  No 
isolysin  present.  No  malarial  parasites  in  blood  smear. 
Condition  of  urine. — Prior  to  the  appearance  of  blackwater  the 
urine  was  stated  to  be  of  a  yellow  colour  ;  none  was  obtainable  before 
the  onset  of  blackwater.  Characters  of  urine  are  given  in  the

:  The  first  two  specimens  of  urine  presented  an  abundant  deposit, 
consisting  chiefl}/  of  red  blood  cells  and  stromata,  and  a  dark  brown 
granular  precipitate,  the  latter  being  one  third  to  one  quarter  of  the 
J  volume  of  the  former.  In  addition  a  few  epithelial  cells  were  seen, 
(j  and  also  bacilli,  mostly  3/“  to  4//  long,  somewhat  less  numerous  than 
i, ;  the  red  cells.  On  centrifugalising  the  urine,  the  brownish  precipitate 
it,  separated  with<lifhculty,  and  a  turbid  upper  liquid,  light  brown  in 
jj  colour,  showing  on  spectroscopic  examination  no  haemoglobin  bands 
in  a  layer  18  mm.  high,  and  giving  on  acidifying  and  boiling  about
