We have seen how the patient's mind can be influenced by changing the posture of his body. Dr. Wilkinson gives very remarkable evidence on this point. 'Double his fist and pull up his arm, if you dare,' he says, of the subject, 'for you will have the strength of your ribs rudely tested. Put him on his knees and clasp his hands, and the saints and devotees of the artists will pale before the trueness of his devout actings. Raise his head while in prayer, and his lips pour forth exulting glorifications, as he sees heaven opened, and the majesty of God raising him to his place; then in a moment depress the head, and he is in dust and ashes, an unworthy sinner, with the pit of hell yawning at his feet. Or compress the forehead, so as to wrinkle it vertically, and thorny-toothed clouds contract in from the very horizon' (in the subject's imagination, it will be understood); 'and what is remarkable, the smallest pinch and wrinkle, such as will lie between your nipping nails, is sufficient nucleus to crystallise the man into that shape, and to make him all foreboding, as, again, the smallest expansion in a moment brings the opposite state, with a full breathing of delight.' Some will perhaps think the next instance the most remarkable of all, perfectly natural though one half of the performance may have been. The subject being a young lady, the operator asks whether she or another is the prettier, raising her head as he puts the question. 'Observe,' says Dr. Wilkinson, 'the inexpressible hauteur, and the puff sneers let off from the lips' (see Darwin's treatise on the 'Expression of the Emotions,' plate IV. i, and plate V. i) 'which indicate a conclusion too certain to need utterance. Depress the head, and repeat the question, and mark the self-abasement with which she now says "_She is_," as hardly worthy to make the comparison.' In this state, in fact, 'whatever posture of any passion is induced, the passion comes into it at once, and dramatises the body accordingly.' It might seem that there must of necessity be some degree of exaggeration in this description, simply because the power of adequately expressing any given emotion is not possessed by all. Some can in a moment bring any expression into the face, or even simulate at once the expression and the aspect of another person, while many persons, probably most, possess scarcely any power of the sort, and fail ridiculously even in attempting to reproduce the expressions corresponding to the commonest emotions. But it is abundantly clear that the hypnotised subject possesses for the time being abnormal powers. No doubt this is due to the circumstance that for the time being 'the whole man is given to each perception.' The stories illustrative of this peculiarity of the hypnotised state are so remarkable that they have been rejected as utterly incredible by many who are not acquainted with the amount of evidence we have upon this point.
