Mr. Arthur Diosy is aggrieved. The ingenious contributor who discovered the nationality of the Whitechapel murderer said that no one had hit upon the suggested necromantic motive. Mr. Diosy said he told the police all about it on October 14, which of course is news to everybody else. He also darkly hints that the dates of the crimes have some occult relation to magical astrology. It would more to the point of Mr. Diosy would tell us where the next murder ought to occur according to the dates of magical astrology.
"One Who Thinks He Knows" - the contributor in question - is an occultist of some experience. When he was a lad of eighteen he studied necromancy under the late Lord Lytton at Alexandria.
