EXPLANATION OF PLATE ILNl— Continued. 



Fig. 6. — Section 6, shows cauliculus, trabecular the commencement of the 

 peduncle, portions of the calices and their cells, &c. 



Fig. 7. — Section 10, shows the cauliculus becoming reduced in size, the 

 peduncle increasing, and the calices becoming deeper. 



Fig. 8. — Section 13, shows the cattliculi almost obsolete, the peduncle on 

 each side joining the outer calix, and the calices very deeply curved. 



Fig. 9. — Section 20. The peduncle is lost as well as the cauliculus, and 

 the irabecula is much smaller. 



Fig. 10. — Section 24. A portion of only one calix is seen. The trabecula 

 still remains. 



Fig. 11. — Corpus centrale from section 14, for comparison with the same 

 structure in Sections 13 and 20. 



Fig. 12. — A portion of a calix {ex.) from Section 15, to show the cali- 

 cular cells and fibres, x 250diam. 



Fig. 13. — Ganglionic cells from Section 24, showing the granular con- 

 tents passing into the fibres, x 250 diam. 



Fig. 14. — Small portion of network of fibres from the lower part of 

 peduncle, x 620 diam. In the upper part oi peduncle the meshes become 

 more elongated, in the trabecule and cauliculus they are less elongated and 

 more regular. 



Fig. 15. — View, from the inner side, of the trabecula, cauliculus, peduncle, 

 and calices of the right side of the brain, separated from all the surrounding 

 parts. This figure is taken from the model mentioned in the text (p. 350).

Fig. 17. — Ditto, seen from the front.
