of the gait. The smaller these variations the more regular the animal 

 is going. It may be illustrated as follows :

For Fig. 96 we find the calculation of such total variations as 

 follows : 



On Straight Course.

(1.34 + 1.67) (2.71 + 1.89) (1.48 + 1.91) (248 + 2.81) 

 Total 3.01 4.60 3.39 5.29 



(average stride = 16.11 ft.) 



Under shoeing of Fig. 95 we have the calculations for variations 

 as follows: 



At Turn. 



nf of nh oh 



(1-79 + 1-74) (1-69 + 1.74) (1-97 + 2.07) (2.04 + 1.99); 

 Total 3.53 3.43 4.04 4.03 



(average stride = 15.27 ft.) 

 and for the stretch following the turn : 



nf of nh oh 



(1.32 + 1.27) (1.19 + 1-29) (1.38 + 1.33) (142 + 1.22) 

 Total 2.59 2.48 2.71 2.64 



(average Stride = 15.84) 

 The figures given are in feet and decimals thereof. 



Comparing the total variations here given we can readily see that 

 the trial on stretch following the turn shows a more even gait and such 

 was the case. In both of the last two instances there is a greater va- 

 riation in hind than in fore, and as a whole the variations are naturally 

 greater at the turn than on the stretch following it. The last figures,
