The vestibular mechanism has two distinctive functions or reactions. These reactions are vertigo and nystagmus, and whenever a vestibular mechanism is irritated these reactions can be obtained. The vestibular mechanism may also concern itself with other reactions, such as past pointing and disturbances in equilibrium, but it does not actually cause these reactions in the same way in which it causes nystagmus and vertigo, for they are the distinctive reactions of this mechanism.
