moulded to the papillar surface of the fold of the stomach. In 

 some cases the leaves of the omasum are quite healthy; some- 

 times they are highly reddened, the vessels which radiate from 

 their attached borders beinc more or less injected, and sloughing 

 may occur in patches. The fourth or true digestive stomach, 

 the abomasum, shows the effects of the disease quite plainly. 

 The contents of the stomach are tluid, and sometimes mixed with 

 blood. In addition to the general redness, the membrane pre- 

 sents circular or irregular patches of a claret color, varying in 

 size from a mere speck to a five-cent piece. The color may be 

 uniform over the patches, but at other times it may be limited to 

 its circumference, forming a colored rim, with a central grayish- 

 yellow portion. In the small intestines spots of inflammation 

 exist. I'lie discolorations vary, some spots being scarlet or rose 

 red, while others are of the deepest purple. The large intestines 

 are also afl^ected. The lining membrane of the respiratory organs 

 jiresents signs of congestion. The lungs and heart show well- 

 marked signs of the disease. 



Treatment. — Treatment is unsuccessful. The disease when 

 induced by inoculation has proved of a less severe nature, and 

 the percemtage of recoveries has been greater than in cases in- 

 duced naturally; but it is almost as severe as that arising from 

 natural rinderpest. If it should gain access to our shores, there 

 is only one method of dealing with it, and that is to stamp it out 

 by destroying not only all affected with it, but also those which 

 have been in contact with iiffectcd animals. 



CONTAGIOUS PLEURO-PNEUMONIA. 



This is a contagious febrile disease peculiar to horned cattle. 

 It is due to a sjoecific virus which gains access to the system, by 

 the lungs. The incubative stage is slow, being two weeks or a 

 month, and the progress of the disease is also of lingering char- 

 acter. The disease induces an extensive exudation within the 

 substance of the lungs, and upon the surface of the pleura, ulti- 

 mately resulting in consolidation of the lungs. This disease was
