Fig. io. A large neurone of the spinal V nucleus of Ameiurus from the same region as that of Fig. 9. 

 GoLGi method. X 195. 



A secondary tract (internal arcuate fibers) is impregnated as it leaves the spinal V nucleus. The 

 neurite of the cell figured probably enters this tract.

Several small intrinsic neurones of the spinal V nucleus are impregnated and one large neurone of the 

 somatic commissural nucleus, whose neurite enters the funiculus ventro-lateralis. The section shows 

 termini of the spinal V tract and dorso-lateral fasciculus in the spinal V nucleus and one terminal from 

 the latter tract in the formatio reticularis.
