The emergency service in the City Hospital of St. Louis gives, I believe, exceptional opportunities for the study of intracranial injuries. In the two years, 1910 and 1912 during which I was on the Visiting-Staff, I devoted my spare time to a study of them.
Of course, all cases presenting external or neurologic signs of localized head injury, that can be directly approached, are treated accordingly, but a great many suggest no special point of surgical attack, mostly cases in which the injury is at the base of the brain; these are usually generalized as fractures of the base of the skull.

A composite picture of such cases might be presented as follows:
