No satisfactory treatment of the disease has been made. An open air life, a generous diet, and a course of iron, and bitters will, however, be of use in serving to improve health, digestion and vigor, to solicit a better production of red globules, and to enable the patient to survive the period of anæmia, prostration and debility. Antiseptics like quinia, the sulphites and the iodides might be used as adjuncts. PNEUMO-ENTERITIS IN SHEEP: HÆMORRHAGIC SEPTICÆMIA: SWINE PLAGUE. Historic note. Microbiology: ovoid bacterium, motile, with polar stain, non-liquefying, chains, grows freely on culture media. Pathogenic to sheep, goats, dogs, hens, rodents, calf, ass. Views of Lignieres, Lienaux, and Conte. Symptoms: Acute form in young; hyperthermia, rapid pulse, troubled breathing, dulness, prostration, sopor, anorexia, congested petechiated mucosæ, offensive diarrhœa, emaciation, wheezing, cough, râles, crepitus, percussion flatness, abortion. Death in 6 hours to 3 days. Subacute form in mature: symptoms moderate, recoveries the rule. Lesions: fœtid carcass, blood staining of skin and organs, exudates, petechiæ, swollen congested lymph glands, peritoneal exudate, congested liver and spleen, gastro-enteritis, pleural effusion, lobular and peribronchial exudates, caseation, congested womb, placenta and brain, bacterium in lesions. Prevention: isolation, disinfection, secretions, manure, drainage, exclude tame and wild animals. Disinfectants. Among the different forms of hæmorrhagic septicæmia in sheep, that observed by Galtier in 1889 in Basses Alpes, and later elsewhere in southern and western France and in Algiers, must be specially noted. It seems to be the same affection studied later by Lienaux, Conte, Besnoit and Cuillé and which prevailed from Tarn in the south of France, to Vendée in the west, and Somme in the north. _Microbiology._ The pathogenic factor found in the lesions was an ovoid bacterium, a little larger than that of fowl cholera, motile, non-liquefying, with polar staining, and often showing in short chains of two or three joined end to end. It grows easily and abundantly in all common culture media, even on potato which fails to propagate the cocco-bacillus of Lignieres. This, with its ready transmission from swine to sheep and _vice versa_, apparently serves to differentiate it from the cocco-bacillus, and the disease from the hæmorrhagic septicæmia of Lignieres.
