Mr. W. Irving Bishop, an educated and able young American gentleman, who is now visiting Scotland, has, at the request of many of the Professors of the Universities of Edinburgh and Glasgow, and many other influential citizens of these towns, been giving several “Exposures of Spiritualism” before very large audiences. By means of a careful study of the mode in which the most famous professional conjurors amuse and deceive their audiences, through a knowledge of the automatic and reflex action of the brain, and by great perseverance and practice in performing the “tricks,” he has been able to rival the most celebrated mediums in befooling an audience. His peculiar anatomical construction enables him to do feats which no ordinary man could do. He offers to pay one hundred pounds, and a well-known American physician adds a thousand to this, if Mr. Bishop cannot do any “manifestation” whatsoever done by any medium, or Spiritualist, after he has been allowed twice to see it done by such a “medium.” His offer has not yet been accepted, either in America or Europe.
