Rh At the end of 168 days the asymmetry of his face when at rest was barely appreciable. He could to a slight extent dissociate movements of eve, nose and mouth. He could almost close his eye by voluntary effort. He could pronounce labials perfectly. He could pucker his lips, although not enough to whistle. He had considerable freedom of facial movement without lifting the arm or shrugging the shoulder. But "Elevation of arm and shrugging of shoulder still called forth general contraction of facial muscles which could not be controlled and which was sustained." The condition of the patient's facial muscles at rest is seen by the photograph taken at this time (Fig. 4). Another photograph (Fig. 5) shows the result of a volitional effort to contract the facial muscles, when aided by the' arm elevated but completely at rest. At the end of 287 days the volitional control of individual groups of muscles had quite completely returned and could 'be effected without associated shoulder movements of contraction in the other. facial muscles' And although emotional expression had not improved to the same extent, it had returned in considerable measure. How involuntary contraction of the face was still produced by a sudden and vigorous elevation of the arm and shoulder is apparent from a photograph taken at this time (Fig. 6). But how, at the same date, symmetrical closure of the eyes was possible, without associated shoulder movements or the contraction of
