THE DISPOSITION OF ACTINOMYCOTIC CATTLE IN THE UNION STOCK 
YARDS. 557 
culin test, the United States Government will have to take 
charge of this work in all the states that give their consent to it, 
and all cattle from other states must be strictly excluded, unless 
they have undergone the test, and are declared free from dis¬ 
ease , this would virtually establish a dead line between states, 
and would soon become so irksome as to cause organized oppo¬ 
sition and greatly delay, if not prove very detrimental to all 
concerned. 
Before leaving this subject I wish to call your attention to a 
marked element of danger in the diagnosis of tuberculosis post¬ 
mortem. 
/ 
Many of you doubtless know that aged cows which have 
been badly kept and whose vital powers are on the decline, very 
frequently have glandular indurations, caseation, and occasion¬ 
ally calcification may be present, without being tubercular in 
their nature. Again we occasionally find actinomycotic growths 
in the lungs and other organs which simulate in appearance 
tuberculosis so closely that it becomes very difficult to distin¬ 
guish the difference. Possibly there are veterinarians who might 
inadvertantly swell the percentage of tuberculosis by mistaking 
such cases for that disease. 
I will now leave this subject with you for your consideration, 
and if I have succeeded in provoking a discussion upon this diffi¬ 
cult problem “How to Suppress Tuberculosis,” I shall feel my¬ 
self amply rewarded for presenting the practical part of this 
question in my own way. 
THE DISPOSITION OF ACTINOMYCOTIC CATTLE IN THE UNION 
STOCK YARDS, CHICAGO, ILL. 
By M. R. Trumbower, D.V.S. 
A paper read at a meeting of the United States Veterinary Medical Association held 
in Philadelphia, Pa., September 18-20, 1894. 
Since October 15, 1888, the State of Illinois has arrested and 
quarantined actinomycotic cattle at the Union Stock Yards, 
Chicago, and at the National Stock Yards at East St. Louis.
