A lady, thirty-one years of age, was suddenly seized with severe haematemesis. She had not suffered from any gastric symptoms previously, but was known to have had an abdominal tumour since the age of fourteen. The tumour now occupied the whole of the left side of tbe abdomen and extended from beneath the left costal margin to the pelvis. It moved with respiration, was dull on percussion, and had a hard smooth surface. The inner border was slightly concave, well defined, and apparently presented a notch about its centre. It resembled a spleen in every particular, with the possible exception that its length was somewhat out of proportion to its width. The haemorrhage proved fatal. A necropsy showed that the tumour was composed of the stomach, which was almost vertical in position, with the pylorus in the cavity of the pelvis. Its contents consisted of a firm mass of hair measuring twelve inches in length, five in width, and four in thickness, and weighing 4 lb. 7 oz. The individual hairs were of all lengths up to twenty inches. The mucous membrane near the great curvature was ulcerated, and the pylorus was dilated to about four times its normal size. The lady's husband stated that whenever his wife became excited she was in the habit of pulling two or three hairs from her head and putting them into her mouth.-Russell.
