Note 2 — SWEDENBORG, MEDIUMS, AND THE DESOLATE PLACES

Besides the well-known books of Atsikof, Myers, Lodge, Flammarion, Flournoy, Maxwell, Albert De Rochas, Lombroso, Madame Bisson, Delanne, etc., I have made considerable use of the researches of D'Ochorowicz published during the last ten or twelve years in Annales des Science Psychiques and in the English Annals of Psychical Science, and of those of Professor Hyslop published during the last four years in the Journal and Transactions of the American Society for Psychical Research. I have myself been a somewhat active investigator.
