In fatal cases the erethism subsides, but fever, dullness and emaciation continue, the case becomes aggravated at intervals, weakness and exhaustion increase, decubitus may become constant or paralysis ensue. The patient dies in marasmus in one to three months. In some the genital erethism is absent from the first. There is dullness, prostration, anorexia, fever, hurried breathing, small rapid pulse, colicy pains, tender abdomen, difficult defecation, coated dung, a glairy (perhaps reddish or fœtid) discharge from the vulva, hot, tumid tender mammæ, arched and sensitive loins, and stiffness of the hind limbs. In all cases alike a rectal examination detects the ovary swollen and exceedingly tender. _Cow._ The same general symptoms appear with characteristic modifications. Restlessness, bellowing, pawing, inappetence, arched, tender loins, swollen vulva with discharge, shiny and perhaps fœtid but without contractions, abdomen pendent and flanks hollow and tender, udder turgid, hot and painful, movements of the hind limbs stiff, halting, straddling. There is greater tendency to salacious movements of the croup. The diagnostic feature is palpation of the ovary through the rectum. In _chronic cases_ more or less of the above symptoms are shown in a greatly mitigated form, but oftentimes there are long intervals of apparent health. Palpation through the rectum is the final test in this as in the more acute cases. _Prognosis._ This is very uncertain. Unless complete recovery takes place in a few weeks, the inevitable consequence is sterility, or death from hæmorrhage, peritonitis, pyæmia, or marasmus. _Treatment._ In acute cases Trasbot strongly urges bleeding in the larger races and leeching of the flanks in the smaller. Mustard plasters to the loins and abdomen, and cold or damp applications to the croup are in order. Vaginal and rectal injections of mucilaginous liquids, containing anodynes and antiseptics are indicated. Opium, belladonna, hyoscyamus, chloral, borax, acetate of aluminium may serve as examples. If needful to quiet the excitement, morphia, atropia or hyoscyamine may be given subcutem. Or the anodynes may be administered by the mouth. As a last resort, and by far the most radical treatment, castration may be performed. With small ovaries this is best done through the vagina in the larger animals, while with large and adherent ones the flank operation is imperative. If the peritoneum is involved, careful antisepsis of the cavity is desirable. In case of adhesions the operation may be risky, but if successful it will obviate secondary infections and establish a permanent cure. Complications must be treated according to their nature.
