the abdomen (the peritoneum). These masseo assume the most 

 Tarious shapes ; there maybe a patch of round, berry-like growths 

 covering a considerable space on the surface of the membrane ; or 

 the same growth may hang down into the cavity, having something 

 like a rude resemblance to a bunch of grapes. They are yellowish 

 •or blueish white iu color ; glistening and hard to the touch, not 

 unlike gristle, and vary in size from that of a pea to perhaps as 

 large as a crab-apple. To this appearance of tuberculosis the 

 Germans have given the name of pearl sickness; the French angle- 

 ■berries. In England it is known as " tJie grapes." 



Tubercles are also frequently discovered in the liver, kidneys 

 and some other of the organs ; but in these situations they are 

 never numerous, nor do they exist in large masses. As pointed 

 out while describing the' symptoms, the great irritation caused in 

 the lung by the presence there of the tubercular growth oftentimes 

 sets up pneumonia, that is, an inflammation of the substance of 

 the lungs ; or bronchitis, that is, an inflammation of the lining mem- 

 brane of the bronchical tubes ; in which cases the post-mortem 

 appearances will show the effects of one or other or both of these 

 •conditions, in addition to those of the tuberculosis proper. 



In the volume published by the Department of Agriculture, 

 :already referred to, on page 404, it is stated: "As regards the 

 frequency of the tubercular processes in the different organs, the 

 following carefully compiled statistics of the disease in Bavaria 

 and Baden may serve as a guide " : — 



Bavaria:— Percent 



Tuberculosis of lungs and serous membranes, . . .41 

 Tuberculosis of lungs alone, ..... 

 Tuberculosis of serous membranes alone (pearly disease) , 

 Tuberculosis of other organs, 



Baden : —

Treatment. 

 Any discussion of the medical treatment of cattle suffering from 

 tuberculosis (consumption) is entirely out of the question. Such 

 animals should be killed as soon as possible, and the carcasses 

 safely disposed of by deep burial ; or, better still, rendered into 

 fertilizer by exposure to extreme heat ; or burned with lire. So 

 that, for us, the whole question of treatment comes to a consider-
