In some respects, the increase of muscular power, or rather of the power of special muscles, is even more striking, because it is commonly supposed by most persons that the muscular power depends entirely on the size and quality of the muscles, the state of health, and like conditions, not on the imagination. Of course every one knows that the muscles are capable of greater efforts when the mind is much excited by fear and other emotions. But the general idea is, I think, that whatever the body is capable of doing under circumstances of great excitement, it is in reality capable of doing at all times if only a resolute effort is made. Nor is it commonly supposed that a very wide difference exists between the greatest efforts of the body under excitement and those of which it is ordinarily capable. Now, the condition of the hypnotised subject is certainly not one of excitement. The attempts which he is directed to make are influenced only by the idea that he _can_ do what he is told, not that he _must_ do so. When a man pursued by a bull leaps over a wall which under ordinary conditions he would not even think of climbing, we can understand that he only does, because he must, what if he liked he could do at any time. But if a man who had been making his best efforts in jumping, cleared only a height of four feet, and presently being told to jump over an eight-feet wall, cleared that height with apparent ease, we should be disposed to regard the feat as savouring of the miraculous. Now Dr. Carpenter saw one of Mr. Braid's hypnotised subjects--a man so remarkable for the poverty of his physical development that he had not for many years ventured to lift up a weight of twenty pounds in his ordinary state--take up a quarter of a hundredweight upon his little finger, and swing it round his head with the utmost apparent ease, on being told that it was as light as a feather. 'On another occasion he lifted a half-hundredweight on the last joint of his forefinger as high as his knee.' The personal character of the man placed him above all suspicion of deceit, in the opinion of those who best knew him; and as Dr. Carpenter acutely remarks, 'the impossibility of any trickery in such a case would be evident to the educated eye, since, if he had practised such feats (which very few, even of the strongest men could accomplish without practice), the effect would have made itself visible in his muscular development.' 'Consequently,' he adds, 'when the same individual afterwards declared himself unable, with the greatest effort, to lift a handkerchief from the table, after having been assured that he could not possibly move it, there was no reason for questioning the truth of his conviction, based as this was upon the same kind of suggestion as that by which he had been just before prompted to what seemed an otherwise impossible action.'
