The celestial telegraph, or, Secrets of the life to come, revealed through magnetism, wherein the existence, the form and the occupations, of the soul after its separation from the body are proved by many years' experiments, by the means of eight ecstatic somnambulists, who had eighty perceptions of thirty-six deceased persons of various conditions: a description of them, their conversation, etc., with proofs of their existence in the spiritual world / by L. Alph. Cahagnet (1851)
