Record of the Tracks on the Ground

(3) The distance which hind foot precedes fore foot on each 

 side, which is to be designated by "overstep." 



Let us, however, look at the table of Fig. 34. There are 20 re- 

 corded strides, whose average is approximately and quickly found by 

 taking the measurement of the last near fore, namely, 384.60, and di- 

 viding the same by 20, which is 19.23 ft. 



This is only a rough calculation to get at the stride quickly. For 

 actual computations we shall have to resort to the method employed 

 in Fig. 36, where the sum total of all the strides divided by their num- 

 ber (80) definitely determines the average stride.
