EXPLANATION OF FIGURES 
4 Stage M; smear. 35. Cells are similar to those in figure 3, but all 
degrees of cornification are represented by variable staining affinity, and clumps 
or masses of cells are frequent. 
5 Alatestage Mzsmear. > 125. Non-nucleated cornified cells of the previ- 
ous stage (massed in center) and nucleated epithelial cells of the deeper epi- 
thelium surrounded by great numbers of polymorphonuclear leucocytes. Some 
of the nucleated cells show clear exoplasmic zones indicating the extraction of 
eosin staining cytoplasm without the entrance of the leucocytes into the cells.
