SLAUGHTER-HOUSE INSPECTION.

Sheep which come to the western markets are less subject to 
disease than cattle and hogs. The most frequent cause for con¬ 
demnation is emaciation. Some of the sheep from Mexico, 
New Mexico and Colorado are infested with tapeworms which 
are so numerous in the small intestines and bile ducts that the 
nutritive functions are greatly interfered with. There is no fat 
and little muscle on the carcass, and that little is so devoid of 
the normal constituents that it remains soft and flabby under the 
same conditions in which the carcasses of healthy, well nourished 
animals become dry and firm. 
Jaundice is quite common and seems to be dependent upon 
pathological derangement of the liver, usually inflammation of 
that organ, but occasionally atrophy or or sclerosis of the hepatic 
tissues. Some cases of jaundice found in sheep shipped from 
western ranges are probably cases of ictero-haematuria ; the spleen 
is large, the liver is black and friable, the bladder full of high 
colored urine, the skin and other tissues stained intensely yellow. 
Condemnation is indicated in these cases. 
A disease somewhat resembling tuberculosis is found in sheep 
grazed on the plains of Colorado and Utah. It is characterized 
by the development of caseous masses in the lungs and thoracic 
glands, the glandular masses often becoming two or three inches 
in diameter and even greater. I do not remember to have seen 
the extension of this disease to any tissues or organs outside the 
thoracic cavity. The disease is essentially chronic and ap¬ 
parently does not interfere with the thriftiness of the animal un¬ 
til large areas of the lungs and numerous glands aie invaded and 
destroyed. When the health of the animal has been impaired 
by this disease it would seem self-evident that the carcass should 
not be used as food. In all cases the organs invaded should be 
destroyed. 
Another disease somewhat resembling tuberculosis is found 
in the walls of the intestines and in the mesenteric glands. It 
consists of nodules of various sizes made up of adventitious 
tissue enclosing caseous pus, and sometimes there is found in ad¬ 
dition small round worms, the Hyposto mimi Columbiana. This is
