"By anatomists, the auditory nerve is associated with the facial, and is the seventh in order of origin from the brain, counting from before backwards. The seventh pair consists of the portio dura or facial, the portio mollis or auditory, and a small intermediate portion." — Chambers' Encyclopedia, 1875
