trie loop after allowing the now, for the first time, 

 possible action of b' b" of the old line. This loop 

 passes instantly forward to its utmost front limit, 

 and at the same time allows the left jaw to set 

 firmly on its "analogical inner bearing" (§ 142)^ 

 given up to the drawing of its temporal muscle. 



The new appuis being now set do-wn on the out- 

 ward bearing, and the old ones bemg raised as they 

 left the ground with the imier bearing presented. — 

 A' a^ and a'^ form, in some horses, with great 

 rapidity, and perhaps a^ before reaching the ground, 

 but in others with a slight delay, t These turn the 

 now raised (here right) fore-foot for its outer bear- 

 ing and bring it forward ; then, when B' is formed, 

 the left (now free) hind-foot is turned out by B' 

 b'^ and b^ is brought forward by B' b'^ and b^, and 

 so on. 



Whether, in the landing, the new hind or the 

 new fore-foot reaches the ground first, depends on 

 the degree of gathering (§ 64.) 



§ 144. The Pace. We include under this name 



* We suppose the sudden pull on vhe reiu collateral with the propel- 

 ling hind-foot, at the moment of the thrust, to be owing to this sudden 

 setting of the lower jaw. It is well known that drawing this rein just 

 as the foot has left the ground, most powerfully checks progression. 



t Where this delay is very marked, the lifted fore-foot not being 

 presented for its outer bearing, retains the inner, w^hich is called 

 ** dishing."
