Hypnotism, the process of inducing sleep by wearying out the optic nerve of the eyes, by making the patient fix them upon a certain spot for a time, generally situated where it is a little wearisome for the eyes to find it. The fatigue thus induced spreads from the ocular muscles to the system, causing deep sleep.
