 with varus, and there had also been disease of the bones of the feet from childhood, and sores upon the hip for eight years. Occasionally she had pain in the tumor, and at the same time in the head ; and at any time in the head if she lay upon the tumor. About two years after this cast was taken, she fell from a horse, and received a severe blow upon the tumor, which enlarged to two or three times its previous size, and threatened to slough; and about four years after the fall she died. 1857.

The patient was an infant, ten months old. The tumor was supposed to have arisen from the spinal canal, but I have
