in an increased difficulty in performing all operations in which these figures are involved. This is the case with the 'high figures' (6 — 9) and also with 3 and 7. It is these figures also which present the greatest difficulties in learning arithmetical tables. Spielrein maintains to have demonstrated the unpleasant feeling tone attach- ing to these figures by Jung's reaction method and by the method of continuously writing down single place figures (Freud's continuous association).
