In the pharynx, at the base and on the borders of the tongue, sometimes also in other parts of the buccal cavity, and in the larynx hemorrhagic inflammations of the mucous membrane, with croupous pseudo-membranes and ulcerations, together with a superficial or deep necrosis may very frequently be found. Among other changes whichi may occur are necrosis of the mucous membrane of the gall bladder, the vagina, and the blad- der, localized or extensive necrosis of the skin, cloudy swelling of the parenchymatous organs, !Fig. 51. So called tutton on the mucous membrane of the large-intestine in hog cholera. The intestines of animals slaughtered during convalescence show at the places of the thrown-off necrotic nodules, ulcera- tions with a granulating base, or small white scars may serve to indicate the pre-existing ulcerations (Gerosat and Bilitz ob- served in exceptional cases cicatrized constrictions of the intes- tines). The lymph glands of other organs may at times also contain caseous foci. The bacillus suipestif er may be demonstrated only in acute cases in the blood, and even then only in small numbers, while in the spleen it may be present in greater numbers. The same organism may also be found in the affected lymph glands, in the necrotic nodules of the intestinal mucous membrane and in the caseous metastatic lesions of the internal organs. The necrotic and ulcerative processes on the intestinal mucous membranes develop quite slowly. Thus in an animal 12 days after the infection there, are, besides the bean-sized mesenteric lymph glands, only
