Fig. 8. Case No. 3. Uterine mucosa; the epithelium is intact but 

 necrotic, a. Note the engorgement of the blood vessels, 

 b;X72. 



Plate V. 



Fig. 9. Case No. 3. Uterine mucosa; here the epithelium is denuded, 

 a, and there is a distinct edematous and necrotic zone, b. 

 Marked leucocytic infiltration is seen at c; d indicates the 

 line at which sloughing would have taken place ; X 72. 



Fig. 10. Case No. 4. Superficial necrosis of a cotyledon forty-eight 

 hours after treatment with menthol-iodine-glycerine solution; 

 a indicates where sloughing would have taken place; X 72. 



Plate VI. 



Fig. 11. Case No. 5. Uterine mucosa seventy-nine hours after treat- 

 ment with Lugol's solution of iodine diluted with an equal 

 volume of water. Sloughing of the necrotic zone by lique- 

 faction necrosis, a. At b, is seen what would have been the 

 surface of the recovered mucosa; here, there is a layer of 

 simple squamous epithelium which, normally, would have 

 grown into simple columnar; at c, is seen a portion of the wall 

 of a gland duct from which the epithelium is flatening and 

 growing out to cover the eroded surface. Observe that the 

 surface is being covered with regenerating epithelium before 

 the necrotic zone is completely detached ; X 72. 



Fig. 12. Case No. 9. Uterine mucosa fourteen days and six hours after 

 treatment with undiluted Lugol's solution of iodine. No 

 fibrosis can be seen; X 72.
