Cases of this kind have been described in mare and cow, preventing copulation and conception, and leading to a distension of the vagina, with a glairy fluid, which obstructed defecation, irritated the bladder and caused violent but fruitless straining, under which the mass would project from the vulva. The centre of the swelling may be penetrated with a trochar or bistuory and enlarged by incisions in several directions. Relief is prompt and lasting. VAGINITIS. LEUCORRHŒA. Inflammation of the vaginal mucosa is usually a concomitant of metritis and like that follows parturition. It will however occur independently from direct injury or infection or from the presence of neoplasms. In dourine and horsepox, vaginitis is a common symptom, to mare, cow and bitch infection is conveyed by coition. Dieckerhoff quotes old chronic cases, also acute ones which extended to the peritoneum and proved fatal in a few days. The common symptom of muco-purulent discharge having a heavy or fœtid odor is together with the discharge from the womb known by the common name of leucorrhœa. The frequent irrigation of the whole passage with antiseptic solutions is usually successful in putting a stop to the affection, unless in case of constitutional infection, or the presence of some neoplasm. TUMORS OF THE VAGINA. The vagina is the seat of different forms of neoplasms in the various domestic animals. Thus cystoma, lipoma, adenoma, fibroma, fibro-myoma, sarcoma and epithelioma have been noted. They are essentially surgical and to be dealt with as such. They are mainly important in this connection as inducing a leucorrhœa, which in the absence of careful examination might be mistaken for that of uterine or vaginal infective inflammation.
