EXPLANATIOX OF PLATKS 24-80, 



Illustrating Mr. E. H. J. Schuster's paper, '' Cortical Cell 

 Lamination of tlie Hemispheres of Papio Hamadryas." 



PLATE 24. 



The two hemispheres seen from difBereut points of view to show 

 fissures and distribution of various types of cortex. 



Fig. A. — Dorsal view of both hemispheres. 



Fig. B. — Yentral view of both hemispheres. 



Fig. c. — Mesial view of left hemisphere. 



Fig. D. — Lateral view of left hemisphere. 



Fig. E. — -Mesial view of right hemisphere. 



Fig. F. — Lateral vieAv of right hemispliere. 



The left hemisphere in figs. A. b, c. d is shaded to show the super- 

 ficial extent of the different types of cortex descriljed. The lettering 

 on the right hemisj)here in figs. A, B, E, and F refers to the fissin-es, 

 while the niimbers show approximately the position from Avliich the 

 strips of cortex drawn in figs. 1-13 are taken. These drawings were, 

 many of them, taken from the left hemisphere, but their position has 

 for the sake of simplicity been transferred to the right hemisphere in 

 the diagrams.
