e various symptoms there may be much uneasiness on the part of the animal, leading in some cases to madness and furious delirium, in others to spasms and convulsions or paralysis. A vesicular eruption of the skin may occur, seen principally between the toes and on the inside of the flank and in the armpits, with subsequent loss of hair and epidermis. Like other infectious diseases, malignant catarrh pursues a longer or shorter course in accordance with the severity of the attack. In acute cases death is said to take place three to seven days after the appearance of symptoms. Recovery, if it occurs, may take three or four weeks. According to statistics, from 50 to 90 per cent of the affected animals die. If animals which have died of this disease are examined, in addition to the changes of the mucous membrane of mouth and nasal cavities referred to above, shallow ulcers in these situations will be found occasionally. These necrotic processes may pass beneath the mucous membrane and even involve the underlying bony structure. In severe cases membranous (croupous) deposits are found in the throat. Similar deposits have been found upon the mucous membrane of the fourth stomach and intestine, which is always inflamed. There is more or less inflammation of the membranes of the brain, kidneys, and liver, and some fatty degeneration of the voluntary muscles. In countries where rinderpest occasionally appears it may be difficult to distinguish between it and malignant catarrh, owing to a general similarity of the symptoms. The principal points to be observed in differentiating between the two are the very slight transmissibility of the latter as compared with the intense contagiousness of the former, and the tendency of malignant catarrh to run a more chronic course than rinderpest, which usually results fatally in a very few days. Only a trained veterinarian who takes into consideration all the different symptoms and lesions of both diseases should decide in such cases. _Treatment._--There is no specific treatment for this affection. Copious blood letting in the earliest stages has been highly recommended, however, as this has a tendency to deplete the system and lessen the exudation of inflammatory products. Antiseptic washes, such as 4 per cent boric-acid solution to the eyes and Dobell's solution applied to the nose and mouth with ice poultices over the crest of the head and frontal region, have also proved efficacious.
