formation of the right posterior line, and the draw- 

 ing on the head suppress a^ a'^ by causing the 

 horse to change the working condyle ;* consequent- 

 ly, the thrusting element being suppressed, the left 

 fore-leg will be darted to the left by the rotary ele- 

 ment of the secondary section of the right anterior 

 line in the neck, and the right hind-leg will follow 

 with an outward step caused by the rotary element 

 of the secondary section of the right anterior line 

 in the body. 



These two stages wUl exhibit the working of the 

 bit for two or more steps ia the same change of 

 direction ; for, when turning to the right, the second 

 action of the bit occurs for the left fore and right 

 hiad-legs as appuis, the first for the right fore 

 and left hind. Thus, at one step, the horse crosses 

 the free legs, at the next, he throws them outward 

 from his body. 



There is still another way of changiug direction, 

 the discussion of which must be reserved for *' cir- 

 cHng on the haunches" (§ 217), of which the move- 

 ment is simply modified by progression being 

 more or less continued as it proceeds. 



* It should be x'emembered, that in the horse the head follows the 

 lower jaw only when the latter is closed ; when open the lateral move- 

 ment disengages it.
