length on fibers 5.9/i in diameter at S^ in Frog 5, and the same 

 procedure is followed in each of the other eight comparisons. 



The foregoing tables, 5, 6 and 7, however, show the internodal 

 values only for the diameter classes 6.3/4 and 'J-'^n, while for our 

 present purpose, it is necessary to use those for 5.9/x and 6.9//. 

 The desired values are obtained by the simple proportional reduc- 

 tion of the internodal length of the 6.3/x class to that for 5.9/<, and 

 of the 7.3/4 class to that for 6.9/t. 



In view of all conditions, the values thus determined, are prob- 

 ably nearly correct, although the method is open to some theoret- 

 ical objections. The comparisons which are thus made possible 

 are given in Table 10.

 nerves which increase 15.6 per cent in length. Internodes from Frog 3, com- 

 pared with those from Frog 5, and from Frog 5 compared with those from Frog 8.
