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.

The following and last experiment that I tried on this occasion was the most crucial. I requested Mr. Zancig to go out with me on to the landing outside the door of the flat. I did not previously inform Madame Zancig nor Mr. Zancig of the nature of the test that I was about to put. Madame Zancig remained in the room with my wife. The door was closed, but not completely. When we were on the landing I suddenly drew my cheque-book out of my pocket, tore out a cheque, and handed it to Mr. Zancig, requesting him to transmit the number. Mr. Zancig observed to me in a whisper that the noise of the traffic in the street was very disturbing. This was true, as the hall door to the street was open. He then remained silent while he looked at the cheque. My

wife then came out on to the landing, and handed me a slate upon which Madame Zancig had during the experiment written the words, "In the year 1875." Mr. Zancig then said aloud, "This is not what we want; it is the number." My wife returned into the room with the slate, and the door was closed, but not completely. It was impossible, however, for Madame Zancig to see her husband. The suspicion arose in my mind that the number on the cheque might have been communicated to Madame Zancig by the words that Mr. Zancig had spoken aloud. I therefore took the cheque that he had in his hand and substituted another one with a different number that I tore from the bottom of my cheque-book. Mr. Zancig remained absolutely silent during the whole time that this second experiment lasted. My wife again came out of the room with the slate, upon which Madame Zancig had written quite correctly, in their proper order, four of the five numbers of the second cheque, with the exception of the last figure, which was wanting, but just as we were returning to the room Madame Zancig said, "There was another

figure; it was four"—which was correct. This impressed me as a good test, with regard to the three last numbers of this cheque, which were different from the corresponding ones of the first cheque. Madame Zancig could not see her husband, and he remained absolutely silent while the experiment was being carried out.

I insert here a note by Sir Oliver Lodge in which he gives an account of an experiment of a similar nature, and also of other experiments which he tried with the Zancigs.

"Independently of the more thorough investigations of Mr. Baggally, I myself was favoured with a private interview with the Zancigs, who were friendly and considerate and helpful; and I tried the experiment of having Mrs. Zancig outside the room, though with door open, and Mr. Zancig with me and quite silent. I wrote five or six figures on a slate, taking care to make no noise, and Mrs. Zancig failed to get them correctly. Zancig seemed distressed at that, and after a little time groaned out, 'Oh, surely you can do this'; almost immediately after which Mrs. Zancig came into the room with the correct figures written on her slate. It

was difficult to see how the sentence had conveyed the figures, but it was instructive to find that utterance of some kind seemed necessary. It was partly this, and partly the manifest difficulty of eliminating all possibilities of code between a pair of performers accustomed to go about together, with years of experience behind them, that prevented me from doing what I probably ought to have done, though circumstances did not render it very easy, namely, to make a serious study of the Zancig phenomena.
