tervals a music box was set into action.The effect of suggestion during the normal waking state was alwaysto give a sharp rise in the curve (Fig. 6) which lasted until thesuggestion ended, when the tracing gradually sank to its formerlevel. On suggesting hypnotic sleep, the phenomena observed werethe same as those already described for the hypnotic sleep curves.During hypnotic sleep, the curve having risen above the normal wak-ing level, each suggestion caused a sudden rise in the tracing of fromone to five millimetres; this rise was followed by a sharp fall in thecurve. The fall was closely related to the suggestion as it invariablyended with the suggestion, the curve then gradually mounted upwarduntil it had reached about the level it had before the suggestion wasgiven. In suggestion during hypnotic sleep there was always a fallin the curve, and in suggestion during the normal waking state thereVi^as always a rise in the tracing, no matter what the character of the 140 E.

GHIJKLMNOPOR I 2 3 45 6.7 Figure 6.— Plethysmographic record of the hand and lower fore-arm, on the right side,taken December 7, 1899- This experiment was to determine the effect of suggestionduring the normal waking and during the hypnotic sleep. Mr. Steele operator, andC. D. H. subject. A fall of 1 mm. in the original curve corresponds to an increase of0 282 c.c. in the volume of the arm. The curve here presented has been reduced 57per cent. The letters and figures show the points at which suggestions were given,and correspond to the following : — A. Suggested that the subject could not open his eyes. B. Suggested that the subject could open his eyes. C. Suggested that the right arm of the subject was swelling. D. Suggested that the arm had returned to its normal condition. E. At this point the subject was left alone in the room in order to see if the curvewould sink to the level it had originally. F. Came back into the room. G. Suggested that the subject could not open his eyes
