drew it on the blackboard. After this she slowly drew a horizontal line through the V, thus:
Mr. Zancig said, "Give the number." She then placed a 2 in the proper position. He then called out, "Give the rest." She thereupon placed the a under the line, thus:
Mr. Zancig said, "What more?" His wife placed the sign of + correctly, but she rubbed it out several times as if in doubt. Finally she put down the sign of + and a capital X, so that her drawing appeared like this:
I have had many other experiments with this gifted couple, but have not yet obtained the crucial test of getting Mr. Zancig to be in
a distant room with closed doors, while his wife was in another room. The possibility of their using a sound code at one time and a visual code at another is therefore not entirely precluded.
Although I have been quite unable to discover the methods by which they can possibly communicate when a visual and a sound code are not detected, yet I will reserve my ultimate opinion until I obtain tests under the crucial conditions that I have named.
Not only did I personally meet with difficulties in endeavouring to explain the performances of Mr. and Madame Zancig, but also the members of the unofficial Committee that I have referred to. I now give an extract from our unofficial report.
