448 THE STOCK owner's ADVISER. 



Symptoms. — There is loss of appetite, dullness^ cessation of 

 rumination, harsliness, and starring of the coat, elevation of tem- 

 perature, rigors, coldness of the extremities, lameness or stiffness 

 when moved, and arching of the Lack. If the skin 'be examined, 

 tumors will be found forming under it in some parts of the body. 

 The tumors may occur in any part of the body, but most fre- 

 quently in the shoulder or tlie loius, and more frequently on the 

 right side than on the left. The tumors are ill-defined and have 

 no lining membranes. They are first hot and painful to the 

 touch, and then become cold and insensitive. If incised, a dark 

 colored and fetid fluid is discharged. As the disease progresses, 

 the tumors enlarge and the animal shows great pain. The breath- 

 ing becomes hurried, the temperature rises, the pulse beats 120 

 to 130 per minute; tympanitis varies in individual cases. In some 

 cases there are lameness and stiffness in one limb, with no ap- 

 pearance of a tumor. In some there are symptoms of derange- 

 ment of the digestive organs. On post-mortem examination, the 

 animal is found to be enormously swollen. Bloody froth is seen 

 issuing from the mouth, nostrils, and anus. On opening the ani- 

 mal gases of bad odor escape, accompanied by spurts of dark 

 blood. The tumors are black, and are found principally in the 

 loins and withers. In some parts of the country such animals are 

 used for human food. I am of the opinion that it is dangerous 

 to human life. The disease is due to a very small germ measur- 

 ing from -^-^^jy-Q to -g-oVir i^^h in length. The germs are found 

 principally in the tumor. Protective inoculation has been 

 practiced with great success, rendering the animal immune to 

 the disease. The germs are taken from the tumor and injected 

 into the jugular vein by means of a hypodermic syringe. The 

 blackest portion of the tumor is cut into small pieces, mixed with 

 distilled water, then triturated in a mortar, squeezed through 

 cloth, and filtered through folds of muslin. Five to ten drops of 

 this fluid is used as an injection.
