A factory-girl, aged twenty-one years, was admitted into hospital with the symptoms of acute intestinal obstruction. A large movable tumour could be felt in the epigastrium. After death the stomach was found to contain a mass of hair weighing twentyone ounces, which had produced extensive ulceration of the viscus. The ileum was ruptured just above the caecum, and on either side of the lesion there was a ball of hair, the larger of which weighed one and a half ounces and had obstructed the intestine at the ileo-caecal valve.-Ritchie.
