to try
some experiments. I will now describe these. Madame Zancig went to the
other end of the room farthest away from where Mr. Zancig, my wife, and
I sat. She faced the wall with her back to us; Mr. Zancig then wrote
with a chalk a line of figures on a slate which he held in his left
hand, and called out the word "Ready." Madame Zancig immediately named
the figures correctly and in their proper order. The same kind of
experiment was tried successfully three times. The results might have
been due to telepathy, but I was not satisfied, as it could have been
possible that the figures were prearranged, or that Madame Zancig could
tell by the sound of the chalk what figures were being written. I also
had in my mind the fact that there is a method of communicating figures
by time-coding.

Mr. Zancig then asked me to write a double line of figures. I handed the
slate to him, and after he had called out "Ready" Madame Zancig
proceeded to cast them up correctly.

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 prope
