 yeast treatment was given at heat periods from March 31, 1916, to June 

 23, 1916, inclusive. On November 8, vagina was douched with warm 

 salt solution before service and on September 22, 1917, soda solution 

 was used in vagina before service. Sometime during the spring of 1918 

 (date not recorded) the writer made an examination and diagnosed 

 pregnancy, apparently of about seventy or eighty days duration. A few 

 weeks later another examination was made by the writer at which time 

 there was no evidence of pregnancy. No record was made of the clinical 

 condition at this time. She was shortly turned out to pasture without 

 further service to bull and remained in the pasture until October 12, on 

 this date the following notes were made by the Avriter: There is a small 

 quantity of clear mucus in vagina in which are seen a few flakes of pus. 

 On manipulation of cervix fifteen or twenty cubic centimeters of a more 

 adhesive drab colored exudate is forced out of cervical canal. The ex- 

 ternal OS and posterior end of cervix is sufficiently dilated to allow the 

 insertion of three fingers although the canal is closed at its anterior end. 

 On rectal examination it is found that the uterus is distended. The 

 walls are tense and simulate pregnancy of the fourth or fifth month 

 although a fetus cannot be felt. The writer is informed that the cow 

 was not bred subsequent to his last examination the previous spring and 

 no bull had been with cow in pasture during the summer. The writer 

 then proceeds to draw some fourteen to sixteen liters of amniotic fluid 

 from the uterus after which a twenty-five to thirty centimeter fetus can 

 be distinctly felt through the rectum. No eftort was made to remove the 

 fetus at this time, believing that it would be delivered in a few days. 

 On November 8th this animal was again examined and the following- 

 notes made: The fetus has been delivered. Uterus is still somewhat en- 

 larged but there is no apparent discharge. On December 14th an ex- 

 amination revealed an adhesive muco-purulent discharge in anterior part 

 of vagina and cervical canal. No enlargement of uterus, tone fair, small 

 cyst in right ovary. Cyst was crushed and cervix cleansed and swabbed 

 with Lugol's solution of iodine and thirtj^ cubic centimeters of a fifty per 

 cent Lugol's. solution was injected into the utenis. The writer did not 

 see the case again until February 1st, 1919, at which time tliere was a 

 muco-purulent discluirge in vagina. External cervix was congested and 

 canal open. Uterus not enlarged and tone fair. The owner did not care 

 to attempt further treatment and animal was slaughtered February 11, 

 1919. 



Macroscopic examination: l^'xternal os is dilated, cervical canal is 

 nine centimeters long and contains a .small quantity of a clear, slightly 

 adhesive, exudate. There is a slight hypertropliy of the first transverse 

 fold of mucus membrane in its lower and right lateral portion. The mu- 

 cosa is of a light drab color. Body of uterus two centimeters in length, 

 mucosa of a slightly mottled light pinkish color. Small areas of a 

 lighter grayish color are seen. Mucosa of posterior end of left horn is 

 similar in appearance to that of the body. Cotyledons are three milli- 

 meters in diameter and are of a grayisli white color, contrasting with 

 gland mucosa. In proximity to one cot^dcilon near posterior end of
