144 DISEASES OF CATTLE. 



yellow lardaceous veins diverging in every direction. The 

 same thick films cover the surface of the lungs. This dis- 

 ease may sometimes linger fiom two to three months in the 

 body before these symptoms appear. 



The cure of this disease has to be undertaken in time, 

 and with great care to prevent the largest part of the herd 

 from perishing. I am prepared to save ninety out of 

 a hundred in all cases. Pleuro-pneumonia is doubtless a 

 contagious inflammation of the lungs, the breast and pneu- 

 monic membrane, with exudation of coagulable lymph into 

 the textures and bronchials. 



Symptoms of the Acute " Lungenseuche" — Cattle Epidemic. 



This disease appears rather suddenly. The afl^ected animal 

 heretofore lively, grows remarkably weak and sullen ; the 

 walk is heavy and staggering, the hair bristly and without 

 gloss ; the ears hanging downward, and the head also. The 

 muscles of the throat often show a' convulsive, trembling 

 movement, the hair at the same time rising in different 

 places. This cutaneous convulsion sometimes develops 

 into a general shudder and fatal convulsions. The ears 

 and horns change from warm to cold, the inside of the 

 mouth being always very hot. The eyes are reddened, in 

 tears ; slime flows from the mouth and nose ; the respiration 

 becomes difiicult, and from time to time a short, weak 

 cough can be observed. The fever now appears and ru- 

 mination ceases. In the beginning there is a violent thirst 

 and no appetite for food. The excrements of the animal 

 are hard and gangrenous, and during the second day diar- 

 rhcEa intervenes, the matter in the beginning consisting of 

 a bad-smelling, dark or black-brown fluid, or a white, 

 bilious slime. After a longer duration of the diarrhoea, 

 the rectum and vagina stand open, the milk ceases, and the 

 udder shrinks together, the animal often gnashing its teeth.
