Fig. 3. Transverse section through the funicular nuclei and visceral commissural nucleus of Cajal 

 of Ameiurus nebulosus. Golgi method. X 75. The drawing is a composite of two adjacent sections, 

 the right side drawn wholly from one and the left from the other. From the Journ. Comp. Neurol, and 

 Psychol., vol. 16, p. 437 (Herrick '06, Fig. 13). 



The endings of the descending sensory vagus root in the commissural nucleus are shown and of the 

 spinal V tract and dorso-lateral fasciculus in their nuclei. One big neurone of the somatic commissural 

 nucleus is impregnated and a few neurones in the lateral funicular nuclei. Dendrites (and probably 

 axones) of the latter accompany fibers from the dorso-lateral fasciculus into the somatic commissura 

 infima in the tract marked y in Fig. 2. Cf. Herrick '06, Fig. 14, for another similar section. 



Fig. 4. A transverse section through the middle of the visceral commissural nucleus of the carp, 

 Cyprinus carpio, showing the decussation of fibers of the descending sensory root of the vagus in the 

 commissura infima, also the decussation of fascicles from the dorso-lateral fasciculus {dec. f.d.l.) and 

 funicular nuclei in the somatic portion of this commissure. The area designated funicular nucleus 

 contains also the spinal V nucleus and receives in this section thick bundles of fibers from the descending 

 secondar}' gustators' tract from the facial lobes {desc. sec. FII). Method of Weigert-Pal. X 30.
