A POLISH mining engineer of Warsaw, medium for telekinetic, teleplastic and luminous phenomena. E. J. Dingwall, research officer of the
SPR, had three sittings with him in August and September, 1923. He was impressed. Lights appeared:
"to come from the medium's mouth and to remain apparently unsupported in space two or three inches from the lips. The brilliancy of each appearance varied, not only as compared with others, but apparently in itself when still in view."
Fronczek was invited to London to sit at the premises of the
SPR. He arrived on April 17, 1925. According to the report of V. J. Woolley and E. J. Dingwall in
Proceedings, Vol. XXXVI, before he entered the sťance room he was disrobed entirely and he offered himself unreservedly for examination. He sat in a pyjama suit. His hands and legs were controlled. He preferred silence or low conversation during the sitting. The phenomena seemed to be preceded by vigorous grinding of the teeth. Greenish, bright spherical sparks were seen, lights appeared on his arm and jerked up towards the mouth. The floating lights were about one to two inches in distance from the lips, a bell was telekinetically moved while both hands and both feet were under control. Throughout the sitting it had been noticed that the medium constantly rubbed his chest with his hands (still controlled) and that soon afterwards a light appeared. As the investigators could not discover the
modus operandi for the supposed fraudulent production of the phenomena they summed up their conclusions as follows:
1. At three sittings out of a total of nine given by Mr. Fronczek at the Society's rooms, phenomena occurred which purported to be produced supernormally.
2. At one of these three the phenomena consisted of the movements of small luminous objects provided by us for the purpose and we suppose these movements to have been brought about by the employment of a cushion held in the medium's mouth.
3. At the other two sittings the phenomena consisted of the appearance of small luminous objects which appeared to come from the medium's mouth and to be attached to it, but we were unable to discover their nature or the method of their introduction into the sťance room.
