When one has succeeded in obtaining raps with contact, one of the surest means of continuing to thus obtain them, is to keep the hands resting on the table for a certain time, then to lift them _very slowly_, keeping the palms turned downward toward the table, the fingers loosely opened, but not held stiffly. It rarely happens under such circumstances, that the raps do not continue to make themselves heard, at least for some time. I need not add that the experimenters should not only avoid touching the table with their hands, but even with any other part of their bodies, or their clothes. The contact of garments with the table may be sufficient to produce raps which have in them nothing supernormal. It is necessary therefore to exercise great care that the dresses of ladies do not come in contact with the legs of the table. When the necessary precautions are used, the raps sound in a very convincing way. In the case of certain mediums, the energy set free is powerful enough to act at a distance. I once happened to hear raps upon a table which was almost six feet from the medium. We had had a very short sitting and had left the table. I was reclining in an easy-chair; the medium, standing, was conversing with me, when a series of raps was made upon the table which we had just left. It was broad daylight in midsummer, about five o'clock in the evening. The raps were forcible and lasted for several minutes. I have often observed facts of this kind. I happened once, while travelling, to meet an interesting medium. He did not allow me to use his name, but I may say that he is an honorable man, well informed, occupying an official position. I obtained with him lively raps in restaurants and in railway lunch counters. He did not suspect that he possessed this latent faculty before he had experimented with me. To have observed the raps produced under these conditions would have been sufficient to convince anyone of their authenticity. The unusual noise made by these raps attracted the attention of persons present and gave us much annoyance. The result surpassed our expectations. It is to be noted that the more we were confused with the noise made by our raps, the more frequent they became. One would have said that some waggish creature was producing them and amusing himself with our embarrassment. I also obtained fine raps upon the floors of museums before the pictures of the old masters. The most common are those made, with contact, upon the table or upon the floor; next, those made at a distance upon various articles of furniture.
