William was in fairly good physical condition. No sensory defect. Weight 125 lbs.; height 5 ft. 3 in. Although well enough developed in other ways he was a marked case of delayed puberty; as yet no pubescence. Strength only fair; for his age, muscles decidedly flabby. A high, broad forehead. Large nose. Peculiar curl of the upper lip. Small, weak chin. These features give him a peculiar appearance--readily interpretable as showing weakness of character. Cranium notably large. With small amount of hair measurements were: circumference 57.8; length 19.6; breadth 15.5 cm. (Head same size as father's.) Expression downcast. Voice high pitched. ``Under dog'' attitude. Slouchy. No analgesia or other signs of hysteria. The performance on tests was peculiarly irregular. In this monograph we have omitted discussion of the results of separate tests, but the citation of the summary as dictated when the case was first studied will prove instructive: The work done on our tests was very irregular, peculiarly so. Perceptions good and most phases of the memory processes fair, but in reasoning ability and especially in tests which require the application of some foresight the results are poor indeed. The failure is remarkable in proportion to what he could do in school work and to his abilities in some other ways. He reads fluently, writes a very good hand, and in arithmetic is able to do long division, but showed no grasp of good method. When at his best he sticks at a job well enough, but does it with no intelligence and does not save himself in the least by thoughtful procedures. We were interested to note that in a game which he said he had played a great deal, namely checkers, he made the most foolish and shortsighted moves. It is only fair to say that this boy varied in his performance from time to time; his emotional condition largely controlled his performance. On the ``Aussage'' or Testimony Test he gave a functional account upon free recital, with 15 details. On questioning he gave 13 more items. Out of the entire number only 3 minor errors. Of 5 suggestions proffered none was accepted.
