1. The fibres 'of the intrapontine facial nerve do not only take the schematic course-the so-called first part, genu and second part, as hither-to said, but passing through or passing over all the sides of the abducens nucleus in various directions, surround the abducens nucleus and then assemble into the second part.
2. A part of the fibres of the facial nerve decussates at the genu.
3. Some of the fibres derived from the trapezoid body end in the motor nucleus of the facial nerve.
4. Some of the fibres derived from the lateral portion of the abducens nucleus seem to join the second part of the facial nerve.
5. Some of the fibres derived from the spinal tract of the trigeminal nerve end in the motor nucleus of the facial nerve.
6. A part of the fibres of the dorsal longitudinal fasciculus (Schutz's bundle) seems to join the second part of the facial nerve.
7. The Mendel's so-called upper facial nerve, originating in the nucleus of the oculomotor nerve, can be seen in my observation, too.
