Experiments and their Verification 



Here we have a recurrence of the tendency of right hind to ex- 

 cessive extension, due no doubt to the application of the toe-weight 

 on the left fore, which caused the latter's increased action, and by 

 sympathy with the right hind, also the greater extension of both. 

 Again, the averages of 20 strides and relative positions of feet tell of 

 the average discrepancy as presented in Fig. 116. In all the diagrams 

 of extensions the scale has been J^ inch to the foot, but the differences

of extensions are conventionally excessive or in disregard to that scale 

 in order to make them more palpable and visible to the eye. 



No.w, turning to Fig. 117, we see a change of extension, or rather 

 a diminution of the former extensions caused by the toe-weight on 

 the off fore. There is a slight increase in length of stride, amounting 

 to about 2^4 inches, and that in itself may account for the slight de- 

 crease of the average distance between the pairs of legs, from 4.08 

 feet to 4.05 feet. But what is more remarkable is the greater approach 

 of equality between the two distances. I have always held it to be of
