eighty to five hundred microns, in which the nuclei of the cells are more faintly- 

 stained and edema more marked than in the deeper portions. The blood 

 vessels of the stroma are engorged and there is marked edema, and in places 

 numerous leucocytes are seen in the edematous areas. 



The glandular changes are not marked. Only in a few areas is there any 

 evidence of slight necrosis of the superficial glands. 



Case No. 4 



Clinical Condition and Treatment: Other than the vaginal and cervical 

 secretions being rather abundant no alterations of the reproductive organs 

 could be detected clinically. Two ounces of menthol-iodine-glycerine pre- 

 paration were injected into the uterine cavity and the cervix swabbed with 

 same. The animal was killed forty-eight hours after treatment. 



Macroscopic Examination: The cervical mucosa is considerably reddened 

 and shows numerous hemorrhages, especially near the borders of the trans- 

 verse folds, except that portion of the mucosa protected by the overlying 

 folds which is but slightly congested. There is a small amount of fibrinous 

 exudate in cervical canal. The uterine mucosa is congested and shows numer- 

 ous small hemorrhages and the surface is covered with a rather abundant 

 coagulated fibrinous exudate. This exudate extends into the anterior ends 

 of the horns but is less abundant there than toward the posterior end. The 

 deeper portion of the uterine wall is edematous. 



Histological Examination: There is but little evidence of necrosis of the 

 cervical epithelium. The sub-epithelial capillaries are engorged and there are 

 numerous more or less diffuse hemorrhages along the crest, of the folds. Only 

 in places are hemorrhages seen in the region of the pits. Considerable edema 

 is seen in places in the stroma. In the uterine mucosa there is a diffuse super- 

 ficial necrotic and hemorrhagic zone to an average depth of five-tenths milli- 

 meter. Just below this there is a distinct zone of leucocj^tes, principally 

 polymorphonuclears and lymphocytes. At places the necrotic zone is sepa- 

 rated from the underlying stroma b}^ a longitudinal fissure as if being de- 

 tached. There is engorgement of the capillaries and edema throughout the 

 stroma. 



Case No. 5 



Clinical Condition and Treatment: The vaginal secretions were excessive, 

 slightly more tenacious than the secretions of estrum, and contained a few 

 flakes of pus. The cervical mucosa normal in color buf excessively moist. 

 Right horn of uterus slightly larger than the left, otherwise no alterations 

 could be detected clinically. One ounce of Lugol's solution diluted with one 

 ounce of water was. injected into uterine cavity and cervix swabbed with 

 undiluted Lugol's solution. The animal was killed seventy-nine hours after 

 treatment. 



Macroscopic Examination: There is about one ounce of a sero-mucus 

 exudate in the vagina. There are a few small hemorrhages in the ventral 

 vaginal mucosa posterior to the external os. The cervical mucosa is moist 

 but slightly congested and shows a number of petechial hemorrhages. The 

 right uterine horn is slightlj^ enlarged. There is a coagulated fibrinous exudate 

 in the cavity of .the right horn extending, well toward the anterior end.. The 

 mucosa is not; unifojfnry congested but the cofigestion.is more intense in tte 

 anterior two-thirds and along the crest of the folds. Betweeii the folds, the
