As he looked one of them disappeared, and he turned the paper over to look for it on the other side; then looked back at the place where he saw it before and said, "That's funny! while I was looking for that the other one's gone." When looking under the paper he noticed some scribbling on the sheet below and said, "Has that writing anything to do with it?" He seemed puzzled by the figures, which were apparently genuine externalised hallucinations. He could not make out why they came, nor why they disappeared. 37 P. (after long gazing): "37." S.: "Is that what you see?" P.: "It's gone. I'm pretty sure I saw 37." Mr. Smith then looked at the 37 again, and we told P. to watch whether it came back, but after a little while he said he thought he saw 29. Similar trials were made with three other subjects, Miss B., T., and W. In all 644 trials were made with the agent in the same room with the percipient, of which 131 were successful, that is, both digits were given correctly, though in 14 out of the 131 cases in reverse order. The chance of success was of course 1 in 81, and the most probable number of complete successes was therefore 8. 218 trials were also made with Mr. Smith in a different room from the percipient, but of these only 9 succeeded, one having its digits reversed; 8 of these successes, however, occurred in the course of 139 trials with P., whilst 79 trials with T. yielded only one success.
