“The hypnotic control of the pulse has been frequently secured by the author. As an example a recent experience may be mentioned. When the subject, a medical student, had reached the somnambulic stage another physician was asked to take his pulse, but not to mention the result. It was then suggested that in ten minutes the rate would be increased ten beats per minute. The patient was left quietly reclining in an easy chair, no suggestions of an exciting or emotional nature being made. A second count showed the exact increase suggested. It was then suggested that in ten minutes the rate would be ten beats less than at first. The same physician announced the result as seven less.”
