4. We have another valuable observation from a specialist in the matter (Dr. Puncernau):
«The entrance and the departure from the trance merits special attention.
They said that they had three calls . . .
They said, I have already had one call . . . I’ve had two calls . . . The length of time between the calls was extremely variable.
One time when I knew that they had two calls, I managed to talk with them, attempting to distract them . . . And especially to make them talk about something that interested them. In the middle of a sentence, they suddenly fell on their knees in the state of trance as if struck by lightning — in spite of being
observed to be interested in what they were discussing.
This drew my attention. This is not the normal way to enter into a hypnotic trance, especially if the person has not been conditioned to a sign or signal. Among the spectators I was never able to find such a sign. Or even to know of what it could consist.»
