ing of tannin one ounce, carbolic acid one ounce, glycerine three ounces, 

 and water one gallon. This line of treatment was continued until October 25. 



Throughout the course of the treatment, attempts had been made to dilate 

 the OS uteri, but had not succeeded, and consequently on October 25 we in- 

 serted a uterine dilator, and forcibly dilated the os uteri until the hand 

 could almost be passed into it. The os was packed with gauze saturated 

 with 2 per cent, lysol. On the following day there was a considerable ac- 

 cumulation of fetid pus, and the os uteri was much swollen. The uterus was 

 washed with 0.5 per cent, potassium permanganate solution, and the os was 

 packed with gauze saturated with lysol solution. On October 27 we suc- 

 ceeded in insertiiig the hand into the uterus. 'Jhe treatment of the 

 previous day was repeated, and continued until November 3, when the 

 cavity was injected with corrosive sublimate solution, after which we 

 deposited in the uterus half an ounce of iodoform and two ounces of olive 

 oil. This line of treatment was now continued, and the case improved rap- 

 idly until November 16, when the patient was discharged convalescent. 



Case 8. — A farm mare, aged 21, was entered in the clinic on May 3, 1905, 

 for chronic metritis, The owner related that a whitish vaginal discharge 

 had been present to some extent for three years. She had given birth to a 

 foal in the spring of 1904, since which time the discjiarge had been much 

 increased. The os uteri was dilated so that the hand was readily passed into 

 the cavity. The uterine walls were flacpid and thickened. The uterus con- 

 tained a collection of fetid pus. The uterus was washed with a 1-2,000 cor- 

 rosive sublimate solution. 



Owing to the paretic condition of the uterine walls, there was difficulty in 

 expelling the fluid. She was given internally nux vomica and sulphate 

 of copper. The case was discharged on the day of entrance, and the owner 

 was directed to wash the uterus daily with 1-2,000 corrosive sublimate solu- 

 tion. It was later reported that in the hands of the owner the treatment 

 proved unsatisfactory and the animal was destroyed. 



b. Cheonic Metritis in the Cow. 



Chronic metritis in the cow occurs chiefly in those animals 

 which are closely housed, used for dairying purposes, and regu- 

 larly bred. 



The causes appear to be chiefly retained fetal membranes or 

 improper manipulations during dystokia. It appears to be 

 especially common in the granular venereal disease, or granular 

 vaginitis. Whether in these cases it results indirectly from re- 

 tained placenta as a consequence of the disease, or directly from 

 the extension of the disease into the uterine cavity, is not clear. 



The symptoms in the cow consist mainly of a chronic purulent 

 discharge, of a dirty gray color, accompanied sometimes by in- 

 different health, with loss of condition and decrease of milk. In 

 many cases, in addition to these general signs, there is, in the
