It thus 324 FACT AND FABLE IN PSYCHOLOGY becomes clear that the swaymg of the body as a wholeconstitutes an important factor of these automatographrecords; that the movements of the head (being farther.

That the muscle-reader is aware of thisfact is obvious from the usual positions which he main-tains towards his subject in reading the direction of thehidden object. To eliminate the record of the swaying of the body,we may experiment with the subject seated; we obtaina distinctive record in which certain phases of thefluctuations have almost disappeared, and in which therecord approximates to a straight line (tracing II. of A STUDY OF INVOLUNTARY MOVEMENTS 325 Fig. 14). One may also eliminate the record of thesway
