consisting  of  granular  casts,  the  granules  being  dense  in  the  smaller 
casts.  Magnification  180  diameters. 
The  appearance  of  the  casts  and  granules  in  the  urinary  deposit 
in  the  black  water  fever  cases  examined  (Figs.  25  to  31)  presented

length  of  the  casts  varied  from  15/1  to  200  fi,  or  more,  their  diameter
