Tests
The tests given to me and to my fellow-investigators through the six sensitives who so ably assisted us during our seven years of experimental work in this little-known field of research—the tests have been so numerous, and were of such a varied character, that I find it somewhat difficult to know which to select out of the hundreds which were recorded in our books officially and elsewhere, the ones which will prove of the greatest interest to inquirers; but I have made extracts from ten of these records, and these, with a few taken from Sir William Crookes's reports on the experiments conducted in his presence, will, in my opinion, be sufficient to prove that we who have witnessed these marvels are neither hallucinated, insane, nor liars when we solemnly affirm that we have both seen and handled the materialized bodies built up for temporary use by entities from another sphere; all the statements made here being true in every detail, to the best of my knowledge and belief.
