A section made almost horizontally through the thalamus, 

 the corpora quaclrigemina, and the cerebellum, following the 

 course of the superior cerebellar peduncles, would give us the 

 relations between the thalamus, the nucleus ruber, tegmental

 somewhat as they are depicted in Fig. 65. 



In the cerebellum the superior peduncles enter the corpus 

 dentatum. 



External to the red nucleus there is shown in Fig. 62 a 

 bundle of fibres which appear to emerge from under the corpora
