TABLE XIX. 



Showing the average areas of the ten largest fibers and of their axis 

 cyUnders in Frog B and Frog II B. 



Frog B. Sex. F. Weight 49.7 grams. Length 205 mm. 



Frog II B. Sex. F. Weight 61.5 grams. Length 234 mm. 



From these facts we seem justified in the conclusion that 

 the relative smallness of the diameters of the fibers is a charac- 

 istic of this particular frog and is common to all the fibers.
