“We know that the phantom is the psychical body projected from the physical body. It is that which enjoys or suffers, thinks, wishes, judges, and perceives all sensations. It is constantly animated by extremely rapid vibratory movements which are certainly the same as when it is within the body. This principle being admitted, we understand that, when it animates the body, its vibratory movements are not projected outside, and that it exercises no appreciable action on other organisms in its neighbourhood. But when it is outside the body its movements are easily externalised. Then the phantom and another person, vibrating in unison, represent two stringed instruments which sound at the same time when one only is touched. If I can obtain this transmission at great distances, we can explain this strange and unexpected phenomenon by the theory of wireless telegraphy or telephony.” The results of the many experiments conducted by and under the auspices of French scientists in particular tend to indicate that in the near future an explanation of the phenomena of vampirism will be forthcoming.
