But, on the other hand, I noticed one thing which would tend to show that the revelations of these mediums rest on an objective reality. At Voiron, one of the regular attendants at my demonstrations is a young girl, Louise----. She possesses a very sedate and thoughtful cast of mind, not at all open to hypnotic suggestion; and she has in a very high degree the capacity, which is comparatively common in a lesser degree, of perceiving the magnetic effluvia of human beings and, consequently, the fluidic body. When Joséphine revives the memory of her past, a luminous aura is observed around her, and is perceived by Louise. Now, to the eyes of Louise, this aura becomes dark when Joséphine is in the phase separating two existences. In every instance there is a strong reaction in Joséphine when I touch points where Louise tells me that she perceives the aura, whether it be dark or light. I thought it well to give the report of one of these experiments almost in extenso, because those who maintain the palingenesic theory find in these the only appreciable argument which they possess. Colonel de Rochas renewed them more than once with different subjects. Among these, I will mention only one, a girl called Marie Mayo, whose history is more complicated than Joséphine’s, and whose successive reincarnations take us back to the seventeenth century and carry us suddenly to Versailles, among the historical personages moving about Louis XIV. Let us add that Colonel de Rochas is not the only mesmerizer who has obtained revelations of this kind, which may henceforth be classed among the incontestable facts of hypnotism. I have mentioned his alone because they offer the most substantial guaranties from every point of view. WHAT HAS BEEN PROVED?
