one-twentieth  column  of  a  whitish  brown  precipitate,  was  obtained. 
From  the  supernatant  liquid  no  haemin  crystals  could  be  obtained,  but 
on  adding  tincture  of  guaiacum  and  hydrogen  peroxide  a  blue  colour 
was  obtained.  Tlic  deposit  in  the  second  specimen  of  urine  contained 
in  addition  a  large  number  of  pus  cells  (about  one  to  every  eight  red 
cells),  some  of  which  had  ingested  red  cells,  and  a  few  blood  casts 
and  brown  granular  casts.

In  the  succeeding  four  specimens  of  urine  the  deposit  consisted 
chiefly  of  pus  cells,  some  of  which  contained  red  cells  or  brown 
pigment  ;  also  m  smaller  amount  red  cells,  partly  or  wholly 
decolourised,  and  granular  brown  pigment,  the  latter  preponderating 
over  the  former  ;  brown  granular  pigment  casts,  occasionally  hyaline 
casts ;  squamous  epithelial  cells ;  cylindrical  epithelial  cells ;  and 
bacteria,  present  in  abundance  in  the  urine  immediately  after 
being  passed.  The  supernatant  liquid  was  free  from  odour  of 
decomposition,  was  turbid,  of  a  dark  amber  colour,  neutral  m  reaction, 
and  gave  on  acidifying  and  boiling  one-fifteenth  column  0!
