Histological examination : Se^rion.s are saved only from y>o.sterior 

 (cr-vix and r-ight nterine hor-n. No abnormalities are observed in the 

 external cervix. The mucosa of right horn varies in thickness from 

 tlirf-e to five millimeters anfl is ernererl by an epithelium averaj^inj^ about 

 twenty-five mierons in height. The sub epithelial cellular zone is fairly 

 well marked though in places apparently extends to a greater depth into 

 the stroma than is normally seen. Xumerous lymphocytes are diffusely 

 scattered through the stroma arsd in places foci of small round cells are 

 seen. There is markefl edema of tlu; stroma and here and there evidence 

 of proliferation of the inter-glandular tissue. The glandular changes 

 are conspicuous and extensive. They vary from vacuolization of only a 

 few cells in a gland tubule to \(-ry marked carvorrhexis with disintegra- 

 tion of the cytoplasm and marked round cell infiltration of the gland 

 luminae. Many of the eotyledons .show cicatrization. 



Case 25. Ouerasej- cow about seven years old. As a heifer this animal 

 was bred persistently before she conceived and calved apparently normal- 

 ly during the summer of 1015. 8he was again bred the following J)e- 

 cember and ealved in September, 1010. For the next year and a half 

 she was bred irregularly but never conceived; at least abortion was not 

 observed during that time. She was treated once during the summer of 

 lOlS, and again onee during the fall for a cystic right ovary. There is 

 no reeord of the nature of treatment. P^bruary ], lUiU, the author 

 examined this cov*- and madia the following notes: There is considerable 

 mucopurulent discharge in anterior vagina. External os is slightly 

 dilated, mucosa is moist and congested but no apparent hyjiertrophy of 

 external cervix. Uterus not enlarged, w^alls somewhat flaccid. liight 

 ovary contains a cyst. The cyst was dislodged, uterus massaged and 

 cervix swalihr-d with Lugol's solution of iodine. Febr-uary 22, animal 

 was examinerj by the author and the following notes recorded. Tliere 

 are about one hundred eubic centimetws of cloudy mucus in anterior 

 vagina and external os. The external os is open and the mucosa slightly 

 congested. T.'terus not enlarged, walls flaccid. No c-yst can be felt in 

 either ovar-y. The uterus and ovaries were massaged and cervix swabbed 

 with Lugol's solntion of iodine: March 22, the following notes were mad(; 

 by I he author: There are about thirty cubic centimeters of a slightly 

 adhesive exudate in anterior jjar-t of vagina. The mucosa of cervix 

 is slightly congested and there are a few friable arlhesions in the jios- 

 terior cervical canal. The left uterine horn is somewhat smaller than 

 right, the wall is flaccid and noticeably thinner than that of right horn. 

 There is a cyst the size of a hazelnut in left ovary. No cyst can br* felt 

 in right ovar-y. No treatment was given at this time as an unfavorable 

 prognosis was made and the animal was slaughlered Marrh 2.'5, \U\U. 



Macroscopic examination: There is an excess of elear mucus in anter- 

 ior part of vagina and external os. Cervical canal is seven and one-half 

 centimeters in length and eruitains a small fpiaiitity of a elear miieus in 

 which a few flakes of pus are seen. The mneosji is not uniforni in color 

 but shows a few in j('Cled areas. There is some hypertrophy of the right 

 lateral portion of the second transverse fold with a small fibrous tag 

 attaching apex of this fold to r>f>f>osile wall of cervix. fJofly of uterus
