A middle-aged woman had suffered for a few months from vomiting, pain in the abdomen, and loss of flesh. Examination showed a large tumour in the umbilical region and left hypochondrium, which was somewhat movable, smooth, non-tender, dull on percussion, and cystic in character. When the abdomen was opened the cyst was found to be connected with the anterior wall of the stomach, and to contain a reddish-brown fluid with crystals of cholesterine. After death another large cyst was discovered between the serous and muscular coats of the organ, on the posterior surface, and two others existed in the wall of the jejunum.-Anderson.
