haps some fibres from the columns and nuclei of Goll and Burdach of 

 the same and opposite sides), vestibular root fibres to the vermis, the 

 ventral spino-cerebellar tract to the vermis, and the pontile fibres to 

 the cortex of the hemispheres. The cortical cells do not send axones 

 outside the cerebellum, all efferent fibres being interrupted in the 

 internal nuclei. The dentate nucleus receives fibres from the cortex 

 of the hemispheres; the globose and emboHform nuclei receive fibres 

 from the cortex of the vermis; and the nucleus fastigii receives fibres 

 from various parts. The axones of the first three form the superior

peduncle; the axones of the nucleus fastigii are fastigio-bulbar fibres, 

 principally crossed, to vestibular nuclei and possibly other reticular 

 formation nuclei. There may be some efferent fibres in the middle 

 peduncle to reticular formation nuclei, but the major part, at least, 

 of this peduncle consists of the ponto-cerebellar fibres already de- 

 scribed. The inferior and middle peduncles are thus largely 

 afferent and the superior peduncle is eft'erent, to red nucleus, thal- 

 amus and nucleus of nerve III. (Fig. 331. p. 552 and Fig. 345.)
