Pain in head began about three years before death, and there was gradually developed an increase of pain, throbbing in the left temple, protrusion of the left eye, with failure of vision, and finally an elastic, pulsating tu- mor in the temple ; her general health being good.

This last operation was followed by wakefulness, delirium, coma, hemiplegia, and on the fourth day by death. (No. 1748.)
