The Angle and Length of Foot 



253 



The first trial under equal conditions between fore and hind feet 

 produced unsatisfactory results. The subject was not at ease, he 

 hopped and shifted and recovered and the variations of the strides of 

 each leg were great in extent because of this lack of balance. 



Retaining the same angles in the second trial (Fig. 187) we length- 

 en the near fore and the near hind on the supposition that a longer fore

foot will stop extension and a longer nind foot will increase it. That 

 is borne out by the resulting extensions of Fig. 187. It is also apparent 

 that by these changes in toe lengths the distance between fore and hind 

 feet has been decreased from 3.87 feet to 3.69 feet, or 2.16 inches, de- 

 spite the fact of a greater stride (16.62 feet), which generally causes 

 a somewhat greater separation.
