Fig. 9 Lateral view of the entire model showing especially the position of the 

 lemniscus medialis (no. 6) with reference to the surface form of the mid-brain, and 

 the putamen and the cortical radiation meduUated at birth. 2J^X. 



Fig. 10 Lateral view of the baby's brain shown in fig. 2, showing a dissection 

 of the pyramidal tract. This is not the cortical radiation meduUated at birth (no. 

 28), but is, in general, parallel to it. The position of the pyramidal tract is indi- 

 cated on fig. 9 by the arrow 36.
