TEXT FIG. 1. A composite plate showing the different cells met with in the 

 mucus of a bacillary dysentery stool. Actually the pus cells are more numerous 

 than represented in the plate. They form at least ninety per cent, of all the cells 

 present. The small rings and irregularly shaped bodies with clear interiors are red 

 blood corpuscles.
