FiG. 2.—Occipital type of skull. The brain is pushed backwards roundan axis passing through the auditory canals. The fissure of Rolandois oblique behind, the Sylvian fissure is nearly horizontal, the externaloccipital protuberance is situated very low down. tremity being very oblique, and the other fissures aresimilarly carried backwards and similarly inclinedtowards the horizontal. In this latter type the wholeof the occipital portion of the cranium (the portionof the cranium behind the auditory orifice) is muchdeveloped in length, and the external occipital pro-tuberance is very low down. It may be said, gener-ally, that a short skull belongs to the frontal type, EXAMINATION OF THE PATIENT 5G3 and a long skull to the occipital. The breadth of theskull is of relatively slight importance in determiningthe direction of the principal fissures. These general principles have been stated beforedealing with the methods of exact cranio-cerebraltopography, because they will prevent grave mi
