Figure 1. Radiary zone in temporal area >.o. 1 (audito-sensory). 



2. No. 2 (audito-psychic). 



3. ,, No. 3 (common temporal). 



4. angular gyms. 



Figure 1 gives some idea of the position and number of the large fibres special to this 

 area. Note that they shun the radiations. In figure 2 there is still a wealth of small fibres 

 but more of large calibre. Figures 3 and 4 are alike in showing both general fibre poverty and 

 an absence of large elements.
