At right angles to the sagittalsuture draw two parallel lines, the anterior of which (c-d) runs along the anteriormargin of the external auditory meatus; the posterior (e-f) touches the posteriormargin of the mastoid process. These two lines will be about two inches the anterior line take a point (g) two inches above the external auditorymeatus, and from it draw a line (g-e) upwards and backwards to the point wherethe posterior line meets th
