These two sheets are pasted around the edges so as to appear as one, and when the person writes a question it is duplicated on the sheet of paper following the one wherein is concealed the carbon paper. The professor has simply to tear out this sheet and inclose it in the cap of the fountain pen. The name of Foster is almost invariably coupled with any test wherein there is reading of sealed letters, pellets, etc., just the same as Slade’s is connected with the slate writing tests. Foster was an inveterate smoker, anywhere and everywhere, especially at his séance, and it was all for a purpose. The visitor who desired a sitting with Foster was asked to write a few questions on small pieces of paper, fold them up separately, and press them into small balls or pellets. Foster would pick one of these up and hold it to his head, as if to try and penetrate it. Apparently failing to do so, he would place it back on the table. This he would repeat with others. Finally, he hands one of them to the visitor, after holding it against his forehead, requesting him to hold it himself. Foster then took a pencil and paper, and scribbled something on it, and then bared one of his arms, and showed it devoid of any preparation. He then rubbed this arm with his hand, and, on removing it, a name was seen. On reading what Foster scribbled on the paper, the visitor finds an answer to one of his questions, and the name in blood red on Foster’s arm is found to be the name of a person addressed by the visitor in the note. Foster had a pellet of paper of his own concealed between his finger tips, and, at some convenient moment, instead of placing back on the table one of the pellets he has just taken up, he substitutes one of his own, keeping the bona fide one in his hand, which he lowers into his lap and unfolds. Holding it in the palm of his hand, he strikes a match and lights his cigar, and while doing so he is deliberately reading the note, which he afterward crumples into a ball and conceals in his hand. He now takes up another pellet and tries to see through it by holding it to his forehead. He, however, fails, and gives it to the visitor to hold, really exchanging it for the one he has just read. He now has his own and the visitor has his. He now allows his hands to lie carelessly in his lap, and, while conversing with the visitor, he pushes one of his coat sleeves up a short distance, and, with a sharp-pointed stick, writes the desired name on his arm, pressing down hard. In a second or two he writes the answer to the visitor’s question, minus the name he has just placed on his arm. He now shows his arm bare, and rubs the spot where he has written, with his fingers slightly moistened, whereupon the name appears in bright pink writing. If it is desired to make it disappear, hold the hand above the head a few seconds. To make it appear again, rub once more with the fingers.
