had  ceased.  Hlackvvater  Fever,  Case  16.  A  large  collecting  tubule  is 
shown  in  transverse  section.  In  the  lumen  of  the  tubule  are  darkly 
sta'ined  coarse  granules,  to  about  5/1  in  diameter,  and  masses 
formed  by  the  coalescence  of  these  granules.  Free  epithelial  cells  are 
also  seen  within  the  tubule,  among  these  masses.  The  cells  of  the 
epithelial  lining  of  the  tubule  are  partially  detached.  Fixed  in
