    also be seen in this illustration. Brcj is the superior cerebellar peduncle, and Crst is the restiform body, forming the inferior cerebellar peduncle. Fig. 31 is a microscopical section made higher up, so that it comes just behind the posterior quadrigeminal bodies, as represented in Fig. 27. In it the motor fibres running to the periphery are seen in the pyramids, Py, and running between these from side to side are the transverse fibres of the pons, Po. Above these, or dorsad, is the lemniscus, Lm, and the lateral lemniscus, Lml, whilst at Frtg is the central field of the tegmentum. The superior cerebellar peduncle is seen laterally to the tegmental field at Brcj. Just above the teg- mental field is seen the section transversely of the posterior longi- tudinal fasciculus, Flp. The aqueduct of Sylvius is very clearly shown at Aq, and above it is the lower portion of the lingula. Fig. 32.
