 VIII. Malignajit Catarrh. 



In this malignant blood disease, the sinuses of the head are affected, 

 causing offensive discharges from the nose. These, at first, are watery, 

 but further along become purulent, and in the last stage are accompa- 

 nied with extensive sloughing. 



How to know it. — It is ushered in with a shivering fit, with all the 

 attending symptoms of fever ; the muzzle is hot and dry ; the animal hangs 

 his head and isolates himself in the pasture ; the membranes are of a bluish 

 color ;the eyes are closed and swollen ; soon the nose and eyes begin to run a 

 watery fluid, and saliva drools from the mouth. The pulse is quick and not 

 over strong ; a dry, hard cough ensues ; the bowels are usually costive, 

 the f CBces being black and hard, but diarrhoea is liable to set in at any time. 

 There is great thirst, but no appetite, and the urine is scanty and high 

 colored. In the course of twenty-four hours, the discharges become 

 purulent, taking off the hair wherever 

 they touch ; the sinuses of the head 

 become so much inflamed, and so 

 filled up with pus, that when the head 

 is tapped on the outside with the 

 fingers, a dull heavy sound is heard. 

 The breath becomes foetid, and the 

 temperature rises to 104 '^ or 105 ° . 

 Cows with calf are apt to abort. 



The last stage is marked by exten- 

 sive sloughing, so much so that some- 

 times the feet and horns come off. 

 The prostration is very great ; the 

 pulse becomes imperceptible ; convul- 

 sions follow, and a great fall in tem- 

 perature, sometimes to 95 <^ , or even 

 to 90 ® ; in some cases, ulceration of the cornea takes place, letting out 

 the humors of the eye. Death follows in the course of nine to eleven days. 

 On post mortem examination, the blood is found to be black and not 

 coagulated. 



What to do. — Remove to a cool isolated place, if in summer; to a warm 

 place, if in winter. Give recipe No. 8, and follow it with Nos. 10, 11 

 and 4, alternating them. Foment the head with hot water liberally, and 

 rub the following liniment well in once or twice a day:
