[Q] It is proper to add that since the recent publication of this paper as a contribution to _The Associated Sunday Magazine_, the charge of fraud has been revived in connection with the "Watseka Wonder." It is asserted by a resident of Watseka that although Lurancy Vennum unquestionably was a sufferer from "nervous trouble," she consciously impersonated the "spirit" of Mary Roff, her motive being a desire to be near one of the Roff boys, with whom she imagined herself in love. X A MEDIEVAL GHOST HUNTER The name of Dr. John Dee is scarcely known to-day, yet Dr. Dee has some exceedingly well-defined claims to remembrance. He was one of the foremost scientists of the Tudor period in English history. He was famed as a mathematician, astronomer, and philosopher not only in his native land but in every European center of learning. Before he was twenty he penned a remarkable treatise on logic, and he left behind him at his death a total of nearly a hundred works on all manner of recondite subjects. He was the means of introducing into England a number of astronomical instruments hitherto unused, and even unknown, in that country. His lectures on geometry were the delight of all who heard them. In Elizabeth's reign he was frequently consulted by the highest ministers of the crown with regard to affairs of State, and was the confidant of the queen herself, who more than once employed him on secret missions. He was interested in everyday affairs as well as in questions of theoretical importance. The reformation of the calendar long engaged his attention. He charted for Elizabeth her distant colonial dominions. He preached the doctrine of sea-power, and, like Hakluyt, advocated the upbuilding of a strong navy. He was, in some sort, a participant in Sir Humphrey Gilbert's scheme for New World colonization.
