in the centre of the forehead, to have 'a certain perception of learning'; and so on." And again "I placed a cork endways over the organ of veneration and bound it in that position by a bandage passing under the chin. I now hypnotized the patient, and ... after a minute and a half an altered expression of countenance took place, and a movement of the arms and hands, which latter became clasped as in adoration, and the patient now arose from the seat and knelt down as if engaged in prayer. On moving the cork forward, active benevolence was manifested, and, on being pushed back, veneration again manifested itself." We are then assured that the subjects knew nothing of phrenology, were perfectly honest, and that no indications were given of the expected results. Braid frankly records his belief in the possibility of calling out phrenological activities by pressure on definite points of the cranium; and the only loophole of explanation which he left open was the one to which he later resorted, claiming that the manifestations may be due to "a system of training during the sleep, so that they may come out subsequently as acts of memory, when corresponding points are touched, with which particular ideas have been associated through audible suggestion." In brief, in this explanation, given in 1854, Braid demonstrated the admitted possibility of arousing emotions in hypnotic subjects by inducing the expressions with which those emotions were associated. But in 1843 he wrote, "If I am to believe the evidence of my senses, therefore, in anything, I cannot see how I can doubt the relation which consists between certain points of the cranium and the mental manifestations which are excited by acting on them during hypnotism. I believe there are few physiological phenomena which can be more clearly demonstrated, especially at such an early stage of their investigation."
