The Main Features of Measurements 299 



The loo-ft. tape line was therefore stretched four times to take 

 the desired 20 strides. From toe to toe the figures are taken down as 

 they are found, taking care now and then to see that the feet on the 

 ground correspond with those in the note book. To get at the length 

 of the stride quickly we may divide the twentieth near fore measure- 

 ment (372.85) by twenty, which is 18.64 ft- If we care to find the 

 total variations from the average we will have to find the twenty 

 strides of each leg and line them up in four columns, with the varia- 

 tions or differences in plus and minus from the average. The complete 

 table is found in the investigation of Lou Dillon's gait. Here we shall 

 not enter upon the matter. 



The next step would be to find the distances from one fore to the 

 opposite fore and from one hind to the opposite hind. This will not be 

 difficult to find from the table of measurements, and for the four legs 

 it reads as follows :
