To such cases the remarks made under the head of pyaemia apply. If the acute lesions become so aggravated as to necessitate slaughter, the systemic condi- tions presented on autopsy will be similar to these seen in acute inflammatory affections generally, associated with those of blood depravation. Malignant Catarrhal Fever is most largely seen in cattle and sheep that have been subjected to the prolonged influence of a foul atmosphere, e.g., in transit by sea in the holds of ships, when the raging of a storm has necessitated the battening down of the hatches ; or where sewage gas is allowed to escape into the houses in which animals are confined. The symp- toms do not usually make their appearance until a space of about forty-eight hours after the exposure has elapsed. There is marked fever with catarrhal symptoms, followed by great prostration; the mucous membrane of the nostrils becomes ulcerated, the mouth foetid, and even the breath exhales a sickly odour, profuse diarrhoea sets in, the discharges having a sickly foetid odour. In addition, there is often a cough, and the lungs frequently become emphysematous or congested. The animal may die in a comatose state. If the animal is killed in the early stages of the malady, there may not be any evidence of the existence of a grave disorder, and con- demnation of the flesh is scarcely justified; but if the disease has been advanced, the usual evidence of the existence of an important form of fever will be found in the blood and tissues on post-mortem examination, and the carcase should be unhesi- tatingly condemned. Stomach and bowel lesions, in the form of patchy congestion, inflammation, and ulceration, may exist.
