'J'he  deposit  present  in  the  urine  on  the  fourth  day  consisted  of 
granular  masses  and  casts,  the  granules  being  fine,  apparently 
rcfractile,  and  brown  in  colour,  held  together  by  hyaline  material.  A 
few  renal  epithelial  cells  were  seen.  No  red  blood  cells  or  stromata. 
No  ci'ystalline  deposit. 
On  centrifugalising  the  first  specimen  of  urine  the  supernatant 
liquid  was  found  to  be  quite  clear,  of  a  dark  brown  colour  without  any 
reddish  tint,  and  on  acidifying  and  boiling  gave  about  one-twentieth 
column  of  a  light  brown  flocculent  precipitate.  The  amount  of 
dissolved  liaemoglobin  originally  present  was  therefore  small, 
presumably  not  exceeding  O' 15  per  cent.  The  total  amount  of  haemo¬ 
globin  in  the  urine  apparently  did  not  exceed  that  contained  in 
gSo  X  o'ooi  5  =  1-5  c.cm.  of  healthy  red  cells.

attributed  to  malaria,  and  commenced  taking  ten  grains  of  quinine 
every  day.  As  his  temperature  did  not  become  normal  he  increased 
the  amount,  five  days  ago,  to  fifteen  grains  a  day.  Ilis  temperature 
then  rose  to  104°  F.,  the  rise  being  accompanied  by  a  rigor  and  cramp 
of  the  stomach,  and  followed  by  profuse  sweating.  Patient  expected
