 hypothesis that

It follows from the foregoing analysis that Boycott's conclusion 

 that "the internodal length increases proportionately more than 

 the diameter" can now be put in the following way: 



The length of the intern ode is proportional to the diameter 

 in any growing stage of the frog in the sense that the former 

 varies with the latter according to the relation given by the equa- 

 tion

III. Takahashi's observations on the length of the internode 

 in different segments of the leg of the same frog. 



Takahashi found that in the same frog, the length of the inter- 

 nodes at different levels on fibers of like diameter in the nerves to 

 the leg, increased towards the periphery. The following is the 

 table quoted from Takahashi' s paper (Takahashi '08, table 8) :
