It can be laid down as a fundamental principle that there is nothing unnatural or occult in the phenomena of hypnotism; what may appear mysterious to us at present will be found to be quite in conformity with the laws of nature when the facts are more carefully determined. The essential factors in most phenomena of hypnotism may be said to be first, the production of a sleepy or dazed condition in which the sub'eet is unusually sensitive to suggestions given by the hypnotized:w and second, the giving of suggestions that are followed by actions, hallucinations, etc. It is my belief that most of the phenomena of hypnotic suggestion can be produced in sane persons in a perfectly normal condition, by merely choosing the appropriate suggestions.
