Yet even at this remarkably early stage H. was found to be in some degree receptive to certain Suggestions conveyed by repeated stimulation under uniform conditions. In the first place, the suggestions of sleep began to tell upon her before the end of the first month. Her nurse put her to sleep by laying her face down and patting gently upon the end of her spine. This position soon became itself not only suggestive to the child of sleep, but sometimes necessary to sleep, even when she was laid across the nurse's lap in what seemed to be an uncomfortable position. This case illustrates what may be called Physiological Suggestion. It shows the law of physiological habit as it borders on the conscious. The same sort of phenomena appear also in adult life. Positions given to the limbs of a sleeper lead to movements ordinarily associated with these positions. The sleeper defends himself, withdraws himself from cold, etc. Children learn gradually to react upon conditions of position, lack of support, etc., of the body, with those actions necessary to keep from falling, which adults have so perfectly. All secondary automatic reactions may be classed here; the sensations coming from one action, as in walking, being suggestions to the next movement, unconsciously acted upon. The consciousness at any stage in the chain of movements, if present at all, must be similar to the baby's in the case above--a mere internal glimmering. The most we can say of such physiological suggestion is, that there is probably some consciousness, and that the ordinary reflexes seem to be abbreviated and improved. _Subconscious Adult Suggestion._--There are certain phenomena of a rather striking kind coming under this head whose classification is so evident that we may enumerate them without discussion of the general principles which they involve. _Tune Suggestion._--It has been pointed out recently that dream states are largely indebted for their visual elements--what we see in our dreams--to accidental lines, patches, etc., in the field of vision when the eyes are shut, due to the distended blood vessels of the cornea and lids, to changes in the external illumination, to the presence of dust particles of different configuration, etc. The other senses also undoubtedly contribute to the texture of our dreams by equally subconscious suggestions. There is no doubt, further, that our waking life is constantly influenced by such trivial stimulations.
