Hardesty, spinal Nerves of the Frog. 333 



This table contains the figures from which were computed all 

 the other tables in this paper. 



The reference figures in the headings of the columns of 

 the table correspond with the reference figures of Figure i, 

 and thus indicate the levels from which the respective sections 

 were taken. The columns of figures are also designated by- 

 letters at the top of each column. 



The columns in heavier type (columns b and h) contain 

 the numbers by which the fibers were found to vary in the dif- 

 ferent sections of the nerve roots and trunk taken at the differ- 

 ent levels. Column d is obtained by subtracting the sum of 

 the ventral and dorsal roots (column c) from the sum of the 

 trunk and dorsal branches combined (column e), and therefore 

 is the difference between the number of fibers present on the 

 distal side of the spinal ganglion and the number present on 

 the proximal side.
