Tuberculosis of the udder is detec-

cases, instead of milk, the udder 
secretes a yellowish, cloudy and 
sometimes flocculent liquid. In 
acute, rapidly developing cases, 
there may be pain and edema of the

tuberculosis the supramammary 
lymphatic glands, situated above 
the udder in the middle of the 
escutcheon, are enlarged and hard. 
If there is doubt as to the character 
of the disease of the udder, the milk, 
or possibly a piece of excised udder 
tissue, may be examined bacteriol-

In tuberculosis of the brain, the 
animal is unsteady and uncertain 
in its movements. It lies down 
much of the time, is usually subject 
to occasional cramps and is apt to
