"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. "Moreover, I questioned Mr. Zancig about codes, and found that he was familiar with a great many. He was quite frank about it, and rather implied, as I thought, that at times he was ready to use any code or other normal kind of assistance that might be helpful, though he assured me that he found that he and his wife did possess a faculty which they did not in the least understand, but which was more efficient and quicker than anything they could get by codes. On the whole, I think this extremely likely, but the rapidity and the certainty and dependableness of the power went far beyond anything that I could imagine as possible between people who depended on supernormal faculty alone. But if there was a mixture of devices between people so skilled, I despaired of bringing the genuine part of the phenomenon to a definite issue. "I do not think that either this or the weight of my other avocations are a sufficient excuse for this neglect, but it certainly was not easy to get opportunities for careful investigation. One of the main difficulties was that they were not free agents, having entered into contracts with managers whose financial interests partly depended upon the continued uncertainty of the public as to the causes underlying their very remarkable performance. Moreover, I knew that so skilled an investigator as Mr. Baggally was more favourably impressed with them than I was myself, and was able to give to them some considerable time and attention.
