N. Y. Herald: “Written by a practising physician, who finds an incidental interest in the scientific study of an important subject. Dr. Mason does not seek to astonish you with the record of hypnotic marvels performed by himself. He deprecates the sensational ways in which hypnotism has been exploited by the periodicals and the press, so that the unlearned and unstable have been duped into all sorts of extravagant ideas as to its possibilities.”

Public Opinion: “A model of simplicity and common sense. The book gives a clear idea of the meaning of hypnotism and suggestion in a scientific sense, but it is to be more highly valued for its exposition of the utilities (and illustrations) of these agents of reform and therapeutics. The chapter concerning ‘Rapport’ is to be especially recommended to those who find in the phenomena of subconsciousness support for supernatural and spiritistic theories.”

Chicago Evening Post: “He discusses the question with earnestness, candor and many illustrations.... He says many things that are sensible and suggestive.”

Churchman: “The book has a very practical value, and considerable ethical significance.”

Boston Transcript: “He repudiates the idea of the supernatural altogether, and in this he is in accord with the best thought of the day.... Interesting and logical.”

Outlook: “Will have many readers.... A not inconsiderable contribution to psychical research.”
