He was carried in an ambulance to his house, and in the transit re- gained his consciousness, so that on arrival at his residence he got out with assistance and walked upstairs to his bedroom. He then again became unconscious, and remained either semi- comatose or wildly delirous for about four weeks. Two ribs on the right side were fractured at the time of the accident. An examination of the scalp-wound, which was of an irregular shape and about three inches long, showed that it extended from above close to the hairy scalp, downwards and inwards towards the median line of the left eyebrow. Beneath this laceration was a depressed fracture of the skull, of some con- siderable extent. • The patient was not trephined, but was treated mainly on the expectant plan.

The color perception was normal in the right eye and normal in the perfect half of the field of the left eye. An ophthalmoscopic examination showed on the right side a normal hypermetropic fundus with clear media, but in the left eye the optic disc was white with clearly defined out- *
