The medium is a young man of twenty-four years of age, of good family, and fairly well-educated. He has been well brought up, and his manners are good. He is a commercial clerk. He is a tall, strong, well-built young man, apparently in robust health. He is intelligent, but does not strike me as having a very strong will. He is easily influenced by his comrades, and was particularly so by the medical student whose irrepressible tendency to cheating I have already spoken about. The student had a great ascendency over the medium, and, in spite of my advice, induced him to experiment too frequently, almost daily. It was easy to foresee the result: the imprudent student and medium both presented visible nervous troubles at the end of a few weeks. The seances were held in the evening with a round table which had a double top; they began in the light, but, in obedience to the behests of the table, total obscurity was speedily obtained. I have always thought that obscurity was asked for by one of the two tricksters, who was then able to give himself up to his heart’s delight, and do as he pleased with his confiding group. They had invited some of their friends—students or doctors—and I was extremely sorry for these new-comers, in that they should have been present at such suspicious seances. To be quite exact, I ought to say that, though I was convinced these young men frauded, I was not always able to bring it home to them. I generally seated myself beside the most turbulent of the two young men, and the hand which I held never once left mine. But the other hand and the other trickster had more liberty, and some of my co-experimenters verified fraud. Moreover, I suspected fraud, because of the appearance of the phenomena, which were of an extremely rough character. The table, raised from the floor, was at times thrown against the observers with so much force, that they have occasionally been seriously hurt. This never happens with true phenomena. The thin top of the table was broken; a ‘phenomenon’ which was caused by exaggerated pressure or violent blows destined to imitate loud raps. Real raps never break a table; its feet are sometimes demolished, when the levitated table falls abruptly, but this is the only damage I have ever observed at serious seances. Notwithstanding the more than suspicious conditions under which we operated, I am not sure that all the phenomena were simulated. In these seances, there seems to have been a mixture of much that was false with a little that was true. A longer observation would have permitted me to come to a more definite conclusion, but the seances were discontinued. Of the phenomena, the authenticity of which appeared probable to me, I will mention raps. Many of them were obtained in the light and without apparent contact; they had all the aspect of the authentic raps I have so frequently observed. But owing to insufficient control, I do not feel able to affirm their reality.
