 lobules, decussate in front of the nucleus tegmenti, and pass to 

 the opposite side of the cerebellum. From here they can be 

 traced into the anterior peduncles and the restiform bodies.

The fibres of the posterior lobules follow an exactly analogous 

 course, and form the posterior decussating commissure in the 

 back part of the white substance of the vermis. 



In the midst of the white substance between the two com- 

 missures lies the nucleus fastigii (nucleus tegmenti), surrounded
