Fig. 526. Diagram of the "association" fiber-tracts of the cerebral hemisphere as 

 seen in lateral aspect. These tracts all bring parts of the cerebral cortex into rela- 

 tion with one another. The integration of the activities of the various parts of the 

 brain is, it may be assumed, effected in this way. (After Howell and Starr. Cour- 

 tesy, Neal and Eland: "Comparative Anatomy," Philadelphia, The Rlakiston
