small  quantity  of  crystals  of  a  carbohydrate  in  somewhat  larger 
rounded  masses  than  those  of  calcium  oxalate.  These  carbohy- 
drate crystals  were  not  included  in  the  estimation  when  it  was  pos- 
sible to  exclude  them. 
The  sections  were  cleared  by  boiling  in  chloral-glycerin  solution.
