Fig. 12 Section 307, at the level of the VIII and motor VII roots. The visceral 

 sensory (communis) root of the VII nerve enters the fasciculus solitarius immedi- 

 ately rostrally of this level. The greater part of Mauthner's cell lies in the plane 

 of this section. Two lateral dendrites of this cell are figilred, one above and one 

 below the fasciculus solitarius, the ventral one of these dendrites having been 

 sketched in from the adjacent section 308. The cells of the motor VII nucleus 

 (nuc.VII.7n.) were also entered upon this drawing from section 308. 



Fig. 13 Section 320, between the VIII and IX roots, at the level of the rostral 

 rootlet of the VI nerve. 



Fig. 14 Section 327, immediately rostrally of the IX and lateral line X roots, 

 including the motor root and nucleus of the IX nerve.
