The medial and larger bundle of fibers from the geniculate 

 ganglion takes a more direct course into the pons (figs. 1, 2, and 

 3, N.Int.m.). Arising from the medial angle of the ganglion it 

 passes obliquely posteriorly and medially across the dorsal sur- 

 face of the motor part of the facial nerve. At the surface of the 

 pons it is joined by the lateral bundle, the two having a conmion 

 central course. 



The vestibular ganglion lies dorsal to and in intimate contact 

 with this bundle. In some sections bipolar ganglion cells were

found along it. Other than these there are no evidences of 

 anastomoses between the nervus intermedius and the vestibular 

 nerve. 



The nervus intermedius, in cross sections through the place of 

 union of its two bundles, is circular in outline. It is located in a 

 triangular interval bounded ventrally by the emerging motor 

 fibers, dorsally by the nervus and ganglion vestibiilare, and me- 

 ially by the surface of the pons. From this position it can be 

 followed into the interior of the pons. Here it passes dorsally, 

 posteriorly and medially through the fibers from the cochlear
