    submucosa, and internal organs with subsequent inflammatory cedematous swellings of the skin, mucous membranes, subcutis, and submucosa. Although the disease may appear primarily ; it is usually a sequela to previous infective diseases, such as strangles, pharyngitis, contagious equine pleuro-pneumonia, and influenza, and, chiefly, during convalescence from these diseases. Chronic catarrh of the lungs, chronic inflammation of the maxillary sinuses, necrosis of bone, intestinal catarrh with suppuration of the lymph follicles, abscesses in the lungs, kidneys, and spleen, and infected wounds, such as those after castration, have been observed to be the starting-points of this disease. It sometimes follows a slight injury to the skin. We do not know whether the virus is a chemical or a bacterial product. Zschokke has observed in depots of cavalry horses the occurrence of several cases in one and the same stable. TV e are as ignorant of the origin of the contagium, as of its nature, and know nothing about the manner in which it enters the body. As horses which are used in the cleaning out of latrines are especially liable to be attacked by this disease ; we may surmise that the infection is conveyed in the respired air. A disease identical with petechial fever of horses appears to occur in cattle, especially in cases of inflammation of the uterus, mastitis, etc. We have several times noticed in dogs haemorrhagic affections of the character of human morbus maculosus ; but no ailment which corresponded to the petechial fever of horses. Bacteriology.—Kolb recently found, three or four hours after death, in people who had suffered from morbus maculosus (purpura haunorrhagica), a bacillus to which he gave the name of “ bacillus hasmorrhagicus.” This bacillus forms oval, thick, non-motile rods with rounded ends, in the form of diplo-bacilli, attached to one another, and sometimes forming pseudo-threads. They cannot be stained with Gram’s solution. Pigeons and guinea-pigs were found to be immune; but dogs, rabbits, and mice became affected with a hemorrhagic ailment. The bacilli were seen in great numbers in the blood of the cadaver. Letzerich states that he has discovered the specific bacillus of morbus maculosus. These statements require confirmation. Anatomy.-—The anatomical changes consist in haemorrhages in the skin; subcutis ; mucosa and submucosa of the nasal cavity, larynx, trachea, bronchi, conjunctiva, pharynx, oral cavity, stomach, intestine, bladder, and vagina ; lungs ; spleen ; kidneys ; and mus¬ cles of the heart and skeleton. Zschokke assumes as the cause of
