Experiments and their Verification 235 



Fig. 176. To counteract toeing in of off fore it is lowered on inside 

 toe and given a slightly longer outside heel ; and the toeing out of the off 

 hind is corrected by lowering of outside toe. 



The change to round toes was merely an idea for the sake of 

 comparing result with squared toes, but it would have been better if 

 certain other conditions, such as angles and weights, could have re- 

 mained the same. It is the same old story of trying to do too much 

 at once, although the object in view was evidently to (i) check the 

 extension of the near fore to some degree, and (2) to cause the near 

 hind to extend more. 



Set as the hind legs seem to be regarding each other's motions, 

 the effort to bring forward the near hind affects the off hind indi- 

 rectly so that the difference between the two is not as great as antici- 

 pated. Again we see the impression of toe in the near hind tracks 

 and that of heels in the off hind tracks ; also in front it was seen that 

 the longer outside heel of the off fore had a retarding effect. It 

 showed plainly at each track as having struck the ground harder than 

 necessary. In both fore the toes showed a good toe impression, but 

 those of the off fore were deeper and proved the greater backward 

 extension of that foot. The longer heels of near hind no doubt had 

 the effect heretofore discussed, namely, that of increased extension. 



Looking at the lateral extension averages in Fig. 179 we see the 

 off hind in a worse position than before, being on the wrong side of 

 the middle line and still between the two fore feet. Paring it as indi- 

 cated had very likely something to do with the position. In the varia- 

 tions from averages the off fore showed the greater activity over the 

 near fore. It made the greater efforts, due, no doubt, to its lower angle 

 and the influence of the near hind, which likewise varied more than 

 off hind ; but, as before set forth, the variations of the hind legs 

 seem to be different in their indications from those of fore, inasmuch 

 as the greater variations from the average stride belong to the defi- 

 cient leg, while with the fore the most active leg has the greater varia- 

 tions from the average. Reaching out with the fore seems to indicate 

 a desire for an increase of speed, while behind there is proof that the 

 leg doing the least varying work is the best adapted for the propelling
