Fig. 1 Left lateral aspect of a wax-plate reconstruction of the cochlear and 

 vestibular systems of the opossum brain. Enlarged 5 diameters. The corpus 

 restiforme, the pons, the brachium conjunctivum and the seventh nerve are 

 included as landmarks. A, decussating vestibular fibers from the nucleus fastigii 

 and the nucleo-cerebellar tract; B, nucleo-cerebellar tract. 



Fig. 2 Posterior aspect of reconstruction shown in fig. 1. A, cut surface of 

 the nucleus fastigii. B, fibers passing from the superior end of the nucleus lem- 

 nisci lateralis to the median line, showing close relation with the decussation of 

 the brachium conjunctivum; C, nucleo-cerebellar tract of the vestibular system 

 and decussating strands.
