Fig. 7. To show the length of the dorsal (D.R.) and ventral (V.R.) roots respectively, in the IX 

 nerve of the five frogs examined, and the corresponding lengths of the internodes on fibers from these 

 roots, the measurements for the roots are given in millimeters on the vertical , to the right, and for 

 the internodes in /i, on the vertical to the left. 



TABLE 13. 



Based on data in Table 12 and comparing the relative increase in the length of the 

 nerve roots with the relative increase in the length of the internodes as shown by 

 a series of ratios.
