Fig. 9.—Coronal section of skull through middle of petrous portion of temporal bone(semi-diagrammatic), to illustrate the position of meningeal suppurations, especiallywith reference to middle-ear and mastoid disease. The illustration also serves to showthe course of the principal motor tracts through the internal capsule and pons. 1, Motorfibers for leg. 2, Motor fibers for arm. These can be followed down through the ponsVarolii until they cross in the pyramids (8). 3, Facial fibers, which cross the pons,and emerge from it to form the facial nerve (7). 4, Internal capsule. 5, Focus in upperportion of pons, causing paralysis of the face and extremities of the same side. 6, Focusin lower portion of pons, causing paralysis of the facial on same side of body as lesion,and paralysis of the extremities on opposite side of body. 9, Jugular vein and lateral(sigmoid) sinus, showing the close relation of the mastoid cells and antrum (10 and 11respectively) to the temporosphenoidal lobe, cere
