The inferior is that part ofthe mastoid lying on the internal side of its conical portion, and 48 DISEASES OF THE EAR is grooved, in a sagittal direction, by the incisura mastoidea; thisis of variable depth, and serves for the insertion of the digastricmuscle. The osseous wall is frequently as thin as paper at thisplace, and, therefore, abscesses can find a ready outlet in thisdirection (Bezold). The superior is traversed by the windingcourse of the lateral sinus, which originates at the torcularHerophili
