From this position the spring takes place, and 

 the fore-foot, when lifted, continues presenting its 

 inner bearing, not only because of the position in 

 which it left the ground, but from its being pres- 

 ently again governed by the upper edge of its 

 shoulder blade, which, on the change of curvature, 

 lies at the rear of a concave of the true ribs. Thus it 

 remains until the formation of the alternate winding- 

 Kne which has discharged the old curvatures in the 

 ophidian and composite S S, extends to the neck 

 S, brings the (now free) right fore-leg in connec- 

 tion with the new posterior convex of the neck and 

 causes it to present for the outer bearing. 



Thus ice sliould have in the trot for a fore-foot^ 

 ichiJe in cqjjnii, the outer hearing from the upper edge 

 of the shoulder blade, while the anterior line of its 

 formation is in action. The inner hearing from the 

 socket^ while the posterior line of its formation is in 

 action. 



But a raised forefoot, having the posterior edge 

 of its shoulder-blade on the rear of the new con- 

 cave of the anterior C of the ophidian S remains, 

 presenting for the inner hearing until the imcK form- 

 ation of the neiv anterior line puts it on the outer 

 hearing, by connecting its socket with the posterior 

 part of the rear C of the neck S.
