Mr J. F. O'MALLEY said that the case was very interesting considered from the point of view of the development of the vestibular and cochlear nerves, because they developed in the same way as a posterior root nerve, so that when the disease was confined to the labyrinth, the cochlear ganglion was likely to suffer total extinction, whilst the vestibular ganglion, which lay in the internal auditory meatus, might escape, although its terminations in the labyrinth were destroyed.
