Dr. E. Yung on the Errors 



I discard here the cases of neurosis, and shall only speak of 

 the hallucinations which one may succeed in exciting in every 

 individual. I must hope to be pardoned for the somewhat 

 charlatanic proceedings adopted in the following experiments, 

 in consideration of the interest of the results obtained. 



Fikst Series. 



Experiments made with the so-called Magnetized Card*. 



Arrangement. — I take any eight cards from a pack and 

 arrange them on a table in a certain figure to which I attri- 

 bute very great importance. This figure, as shown in the 

 following diagram, corresponds to the human face (1 card for 

 the forehead, 2 for the eyes, 1 for the nose, 2 for the ears, 

 1 for the mouth, and 1 for the chin). Then, after having

magnetic fluid," I admit that the experiment which I am 

 about to show to the persons present seems to me to prove 

 that there are certain phenomena difficult to explain without 

 a "fluid." I then touch all the cards in order to impregnate 

 them with " my fluid," and declare myself ready to try the 



* This card trick is very old and very well known. I do not know, 

 however, that it has ever been made use of for methodical experiments. 

 The trick itself was shown to me by my learned friend Dr. Leon Fre- 

 dericq, Professor of Physiology in the University of Liege. He witnessed 

 some of the results described further on.
