On Dec. 3, 1891, I visited Mrs. C., who lives three miles in the country. She is a large, healthy woman with a good family history as to health, morals and cleanliness; has always lived on a farm. The house in which she lives is a large, new frame building, situated in a healthy location. She was then, at the age of 39 years, nursing her second child, which was healthy and in its seventeenth month. The mammæ were of medium size, and had never given her any trouble previous to this attack. The family had not been using rye bread or buckwheat cakes.
I found a deep gangrenous ulcer on the left breast, extending from near the nipple toward the median line; irregular in outline and about three inches in diameter. The margin of the ulcer was a black color, the bottom being covered by the characteristic ashy-gray coat.
