made him ill and he flung it away with every expression of disgust.
*This is an instance of what is called post-hypnotic suggestion. Dr.
Cocke tells of suggesting to a drinker whom he was trying to cure of the
habit that for the next three days anything he took would make him
vomit; the result followed as suggested.

The same phenomena that was shown in unclasping the hands, was next
exhibited in commanding the subjects to rotate them. They immediately
began and twirled them faster and faster, in spite of their efforts to
stop. One of the subjects said he thought of nothing but the strange
action of his hands, and sometimes it puzzled him to know why they
whirled.

At this point Dr. Flint's daughter took charge of the class. She pointed
her finger at one of them, and the subject began to look steadily before
him, at which the rest of the class were highly amused. Presently the
subject's head leaned forward, the pupils of his eyes dilated and
assumed a peculiar glassy stare. He arose with a steady, gliding gait
and walked up to the lady until his nose touched her hand. Then he
stopped. Miss Flint led him to the front of the stage and left him
standing in profound slumber. He stood there, stooping, eyes set, and

among the rest of the class. One young fellow in particular, laughed so
uproariously that tears coursed down his cheeks, and he took out his
handkerchief to wipe his eyes. Just as he was returning it to his
pocket, the lady suddenly pointed a finger at him. She was in the center
of the stage, fully fifteen feet away from the subject, but the moment
the gesture was made, his countenance fell, his mirth stopped, while
that of his companions redoubled, and the change was so obvious that the
audience shared in the laughter--but the subject neither saw nor heard.
His eyes assumed the same expression that had been noticed in his
companion's. He, too, arose in the same attitude, as if his head were
pulling the body along, and following the finger in the same way as his
predecessor, was conducted to the front of the stage by the side of the
first subject. This was repeated on half a dozen subjects, and the
manifestations were the same in each case. Those selected were now drawn
up in an irregular line in front of the stage, their eyes fixed on
vacancy, their heads bent forward, perfectly motionless. Each was then
given a suggestion. One was to be a n
