feet, or 2.46 inches, as given in Fig. 97. There is, therefore, a closer 

 approach between right fore and left hind by nearly i inch (2.46 1.38) 

 than there is between the other two moving legs. Both front feet are 

 shod exactly alike ; hence the difference must arise from the uneven 

 extension of hind feet. In this case the leg that lagged before was the 

 left hind and the foot was given the heavier shoe and the shorter and 

 higher heels. The result is what was expected; but such greater ac- 

 tivity of the left hind is transmitted in some degree to its mate, the

off fore, and hence this leg has the greater extension over its opposite 

 mate, the near fore. In many other cases such influence of one foot 

 upon its moving mate has caused annoying results. 



As has been before indicated we can balance the feet with reference 

 to front or hind extension, but we must also take into account the inter- 

 relation of the fore and hind as they move in closely related or corre- 

 lated pairs. Hence a change in one hind foot will call for a change in 

 the correlated fore foot, always with a view to having the distances 

 between the fore and hind, that move together, as nearly the same as 

 possible.
