WHEN the cow, shown in the accompanying photograph, was purchased it had a small fluid-filled lump on the left knee.
The swelling did not appear to be painful but gradually increased in size until it assumed the proportions shown in the picture.
It was a typical case of "big-knee," one of the less common manifestations of Brucellosis—the disease commonly known as contagious abortion—and a blood test of the animal confirmed the diagnosis.
