readily extended forward. The swelled heels on both hind, how- 

 ever, tended to increase the distance between extremities (3.44 ft.). 

 An intermediate effect of squared toe on near hind, as compared 

 with the two previous results, occurs in Fig. 167. Here the squared toe 

 checks the former greater extension of near hind with reference to the 

 equally long off hind. The distance between the extremities (2,96 ft.)

is greater than in Fig. 165 (2.56), but still less than in Fig. 166 (3.44). 

 In Fig. I43-A this distance was also relatively small (2.88 ft.), but 

 in Fig. I43-B it is increased to 3.59 ft., and the whole question of sep- 

 arating the extremities reasonably to insure a free open reach in front 

 hinged on the easier forward extension of the left fore leg. Not only 

 was this effected by the increased extension of off hind, as in Fig. 

 I43-B, but also by the longer toe and lower heel (50) of that neas
