M. Bonjean has developed the three following theses: First, that the action of magnetism is not explained by the hypothesis of a fluid, that we cannot speak with M. Ochorowicz, of "a certain tonic vibratory movement which propagates itself outward from the periphery of the body," but that it is explainable by simple suggestion; second, that the power of suggestion is almost unlimited; and third, that though verbal suggestion is incontestable, mental suggestion remains doubtful until proof to the contrary. M. Bonjean thus sides with MM. Ochorowicz and Delbœuf, and the whole school of Nancy, against that of the Salpêtrière. He endeavors especially to show the serious consequences, in criminal and civil affairs, of immoral suggestions, the dangers of which he reproaches M. Gilles de la Tourette with having concealed far too much. His personal conviction does not rest itself solely on the expositions of others, but on experiments which seem to have been conducted with prudence. Extraordinary as this almost passive obedience of a subject to the suggestion of an act which is repugnant to his moral tendencies appears, we come in a position, it seems to me, to comprehend it by the observation of the degenerate patients of our asylums in their various manias. The dipsomaniac resists with all his power the impulse to drink, and the kleptomaniac the impulse to steal; they fight against it even to agony, but they end always by yielding to it. "It was stronger than I"; such is the formula that we have noted most often in the answers of these unfortunates. And remark, that the dipsomaniac does not drink for pleasure, but by compulsion, be the beverage what it may, water, urine, or petroleum; just as the kleptomaniac does not steal with a view to enjoying the product of his theft, which he ordinarily abandons or restores, but steals to deliver himself from agonising torture. In this manner also the onomatomaniac acts, who is seeking a word, and who rises at night to consult the dictionary, etc. The hypnotised subject is in the same predicament, whatever pathological difference there may be between the two; his personality has momentarily sunk in hypnosis, as does that of an insane person during the attack of insanity; his moral resistance must finally yield, and it is not at all remarkable that it does. The volume of M. Bonjean ends with an interesting discussion of the celebrated case of Lully. The deceit that gave rise to belief in suggestion without words or gestures appears to be established; the subject reads from the lips of his magnetiser. * * * * * Let us turn to the fine work of M. R. GAROFALO, _La Criminologie, Etude sur la Nature du Crime et la Théorie de la Pénalité_. M. Garofalo has himself translated his work from the Italian; this second edition is entirely recast.
