HYPNOTISM AND MESMERISM. 103
ignorant or unmindful of the potency of suggestion in the production of mesmeric phenomena subsequent to the induction of the condition. But, like the Paris school of hypnotists, they hold that suggestion plays a secondary rdle in the production of many of the phenomena. That they are wrong in this will more fully appear in subsequent chapters of this book.
The points of difference between the three schools of this science have now been reviewed, and the theories of each briefly stated. It is found,
i. That the Nancy school attributes all the phenomena, including the induction of the state, to the power of suggestion, and that it is to the psychic powers and attributes of man alone that we must look for an explanation.
2. The Paris school, on the other hand, ignores suggestion as a necessary factor either in the induction of the state or in the production of subsequent phenomena, and seeks an explanation of the subject-matter on the bases of physiology and celebral anatomy.
3. The mesmerists ignore suggestion as a necessary factor at any stage of their experiments, and explain the whole on the magnetic fluid theory.
We also find three distinct methods of inducing the sleep ; and as it is of the utmost importance to bear the different methods in mind, they will be here restated :
The Nancy school, true to its theory, employs suggestion alone to induce the condition. Passes are sometimes made over its subjects after the manner of the mesmerists, but only with a view of giving an air of mystery to the proceedings, and thus adding potency to the suggestion.
The Paris school employs physical means to induce the state almost exclusively. They are practically the same as those employed by Braid, namely, causing the subject to gaze steadily at a bright object, although many variations of the method have been introduced, such as flashing an electric light in the eyes of the subject, striking a gong without warning close to his ears, or by some peripheral excitation, such as rubbing the scalp, etc.
