The author, with the companions of his tour, could not pass Nancy without stopping to see “the masters in the science of hypnotism” there. An account of what he saw and heard gives the author the opportunity of repeating “That he does not regard forgetfulness on awaking as characteristic of profound hypnosis, and that experience is against the efficacity of criminal suggestion unless the subject is criminally inclined.” The fêtes at Montpellier commenced with a religious service in the Cathedral, during which the Bishop, M. de Cabrières, preached a sermon so liberal in tone, that M. Delbœuf thinks the time is arriving when the church will demonstrate that Moses was the precursor of Darwin. At the University reception which followed, M. Delbœuf sought out among the professors for his friend M. Dauriac, whom he had figured when first he heard from him as small, thin and dark, but now found, in accordance with the usual rule in such cases, that he was tall, robust and fair. In the course of their subsequent conversations the two Professors made mutual confidences, M. Dauriac confessing that his true vocation was music, and that he was preparing a work on the psychology of the musician; while M. Delbœuf informed his friend that he was about to reply to his criticism of “La matière brute et la matière vivante,” and that he would throw the greatest light on the origin, which was still obscure, of life and death. If the genial Liège Professor can do this, he may be the first to reap the benefit referred to in his own words: “The discovery of the cause of death could not fail to assure the immortality of its author and its inspirer, and sooner or later that of humanity at large.” For, according to a medical adage, if the cause of a disease is known it is already conquered.
