FIG. 131. THROUGH THE WIDEST PART OF THE FOURTH 



VENTRICLE. (Sherringlon.) 

 Taken in the line 111, Fig. 108. 



Py. Pyramidal fibres cut transversely, tr. P. the superficial (ventral) trans- 

 verse fibres of the pons. The shaded part of the pons (gr. P.) indicates grey 

 matter mingled with the deeper transverse fibres. F. the fillet. Tp. the tra- 

 pezium. C. H. the restiform body or inferior peduncle of the cerebellum, cut 

 across obliquely. S. P. the superior peduncles of the cerebellum, r. raphe. 

 s. o. superior olive. C. D. corpus dentatum of the cerebellum. Ef. n. the nucleus 

 of the roof. s. g. tubercle of Rolando. V. 8. section through sulcus in the vermis 

 superior of the cerebellum, t. bundle from the olive to the lenticular nucleus. 



VIII. the eighth or auditory nerve, its ventral or vestibular root, proceeding 

 from VIII. ft. the front part of the lateral, auditory nucleus. VII. n. the nucleus 

 of the seventh or facial nerve. VI. the nucleus of the sixth nerve. VII. g. 

 fibres of the seventh nerve cut across as they sweep round the nucleus of the 

 sixth before issuing from the pons as VII. 



4th. the fourth ventricle, here roofed in by the cerebellum ; the shading of 

 the central grey matter immediately surrounding the ventricle is, for the sake of 

 simplicity, omitted.
