the other. In other words, in this case the near fore exceeds the off 

 fore by 0.97 ft., or 11.64 inches, and the actual difference of extension 

 behind is 0.935 ^-> or ^ ls 11.22 inches greater for the near hind. This 

 makes the separation between the correlated or diagonally opposite 

 feet equal to the- sum total of these two differences, or 22.86 inches, 

 whereas ordinarily the difference should be only nominal. 



Now again, we have by the crosswise differences in the measure- 

 ments of the near fore and off hind and again of the off fore and near 

 hind the following two averages of the totals : 



Dist. correlated feet.

showing an actual difference of 1.99 ft., or 23.88 inches. Under ordi- 

 nary circumstances this should equal i.9 + i.87 jOr 1.905, as the dif- 

 ference between opposite feet indicated above. The two calculations 

 should tally and are always a check on the correctness of the figures. 

 But here we have a difference of 0.085 ft. (1.99 -- 1.905), which is 

 one-half of the difference of the two extensions of the hind over the 

 fore, namely, 0.17 ft., as given above. This difference in extension 

 appears also in the sums total of the fore and of the hind extensions, 

 as given in the average distances between the opposite feet, namely: 



7.35 + 541 = 12.76 for the fore, and 

 7.40 + 5.53 = 12.93 for the hind extensions, 



giving us a difference of 0.17 ft. between the two hind and the two fore ; 

 that is to say, 12.93 12.76 w {\\ a g a i n express the actual difference 

 in extension between fore and hind extensions. This difference of 

 0.085 is also found if we take the difference between the distance of 

 the correlated feet and that of the opposite feet as found in inches, 

 namely, 23.88 22.86, which is 1.02 inch, or 0.085 ft- 



If there is any difference of extension between the fore and the 

 hind it will generally appear in the averages of the fore and of the 

 hind, when the averages of the distances of one foot to the opposite one
