Platk II. Median view of a model of the cTanial nerves in the same 

 embryo shown in Plate I. A portion of the spinal cord is represented and above 

 that everything is cut away, excepting the sensory bundles and motor nuclei 

 of the different nerves, together with that portion of the marginal zone which 

 is to form the funiculus anterolateralis. The somatic motor nuclei are 

 colored red, and it can be seen that they form a column that is practically 

 continuous with the cells of the ventral horn of the spinal cord. Enlarged 

 about 30 diameters.
