For these reasons, therefore, the first sittings were at the editorial offices of the _Examiner_, where the editors were as much puzzled as anybody else. They were at once convinced that, however he performed his feats, Dr. Schlesinger was at least not a bungling master of the black art. Several intelligent observers were present, among them one or two of the brightest newspaper men in the city. The experiments were not only carefully noted, but they were viewed with grave suspicion. They were, however, wholly informal and merely preliminary to the more important and prolonged seances that followed at the office of the Mayor of the city, and later at the office of and in the presence of the city's Chief of Police. A few facts concerning the occurrences at the _Examiner_ office are given that the reader may have the full benefit of the story. One of the investigators (Managing Editor A. B. Henderson) wrote a number of names on slips of paper, before Dr. Schlesinger arrived. They were not seen or known to any one save the person that prepared them, and the slips on which they were written were carefully folded and clasped in a bundle, by a rubber band or elastic. Great pains was taken by Mr. Henderson to prevent the medium from handling or seeing the slips. Without seeing the writing, Dr. Schlesinger at once gave the names correctly. One of them was that of Thaddeus Stevens, the eminent Pennsylvanian; and when the folded slip on which his name was written was touched by Mr. Henderson, the medium said: "That is the name of Thaddeus Stevens, who knew you well. He calls you Alexander, and sends you his love." Then the name of the sitter's deceased uncle was properly announced, though it had not been written on any of the slips. Correct information was also given concerning the uncle's religion while "in the flesh." S. S. Chamberlain, now Managing Editor of the Philadelphia _North American_, (then News Editor of the _Examiner_) was one of the investigators. He wrote down, on separate slips of paper, the names of many living and dead persons, but, contrary to the medium's request, he did not write the names of persons he had ever known. In a few moments Dr. Schlesinger read the names correctly while the slips were beyond his reach, and firmly clasped in Chamberlain's hand. They were of such persons as John Ruskin, Ralph Waldo Emerson, Shakespeare, Longfellow, etc. A faithful report of all that occurred was submitted to the managing editor of the paper, who at once decided that a series of similar experiments, conducted at the office of the Mayor of the city and others, in broad daylight, would make the basis for some interesting Sunday specials. Under his instructions I arranged the seances, and was present at all of them. I subsequently wrote a faithful account of what occurred, but the articles were rejected by the editor of the Sunday _Examiner_ for personal reasons. This volume embraces the substance of what was then prepared.
