 mapping the case, forming motor habits slowly. His M. V. 

 was 2.56. 



Graph 4. The principles thus far detailed in describing graphs 

 2 and 3 furnish a partial interpretation of the unusual curves of 

 C (P) and of H (U) of this graph. C's strong place-memory 

 enabled him to forge ahead to 6 P where an abrupt break occurs,

 the cards. He never passed beyond the earlier part of the con-

 section. His M. V. was 3.15. 



H (U) was handicapped throughout by a poor place-memory, 

 and to some extent by his failure to learn the order of the cards. 

 The plan of the work proved a stumbling block and at times he 

 suffered a complete relapse. He claimed that the stimulus was
