The author has written a further article on the Beauchamp case of which he had previously published a study in 1908. His theory of the psychogenesis of multiple personality as evidenced by the case of Miss Beauchamp does not add much to what has already been published on the academic investigation of these cases. A kind of psychological analysis was carried out on the subject but no psycho-analysis, therefore the findings are of no material interest to psycho-analysts.
