As Madame Zancig named all my figures aloud as she was summing them up, this experiment was of a more complicated nature than the previous ones; nevertheless, I was not entirely satisfied, as time-coding in putting down the resultant figures by Mr. Zancig, and the hearing of the sound of the chalk by Madame Zancig when I was writing my own figures, might have accounted for the favourable result. To prevent the possibility of communicating by an electrical or other apparatus concealed under the carpet, I requested Mr. Zancig to raise his feet from the floor. He immediately complied by sitting on the table, where he remained to the last experiment. Madame Zancig then retired into an adjoining bedroom with a slate in her hand; the door was closed, but not entirely. My wife wrote down two lines of figures, the slate was handed by her to Mr. Zancig, who called out "Ready," and he then proceeded without speaking to add them up. Madame Zancig then came into the room with the correct result written by herself on her slate. This was a more crucial test than the last, but still, although visual-coding was excluded, sound-coding while Mr. Zancig was writing the resultant sum was not entirely so. Then followed the experiment of transmitting a selected line in a book. Mr. Zancig handed me a book and asked me to open it at any page and to point out a line. After I had done so I handed the book to him. He called out "Ready." Then his wife opened a duplicate book at the proper page, and read the line which I had selected. Doubtless the words of the line were not communicated telepathically or otherwise by Mr. Zancig, but only the number of the page and the number of the line counting from the top of the page. Nevertheless, it was difficult to discover by what method this was done, as Mr. Zancig simply called out "Ready." There did not appear to be time for the numbers of the page and line to be transmitted by time-coding. The reader will observe that as the experiments proceeded they appeared to present increasing evidence that true telepathy was at work.
