In the practice of Dr. B. B. Palmer, I.S.C. '11, of Wayzata, Minn., a few sporadic cases of an unusual mastitis occurred which had not previously been amenable to treatment. Death occurred soon after the onset of symptoms. On Nov. 7, 1943, another of these cases was brought to the attention of Dr. Palmer.
