24 HOW TO JUDGE A HORSE. 



becomes broader, and tlie weight of the latter grows 

 larger. The fastest, and so very shoulder free race- 

 horses, have the thinnest necks. 



The elhoio joint connects the arm bone with the 

 fore arm. This latter consists of the fore arm bone 

 and the elbow bone ; the latter, with its elongation, 

 called the lever of the elhoio, extending considerably 

 beyond the rear part of the elbow joint. On this 

 lever are fastened the extensor tendons, emanating 

 from the shoulder-blade, and acting on the 

 elbow bone when the leg is supporting or push- 

 ing the weight forward, like on a one-armed lever, 

 the prop resting on the ground, and the weight to 

 be lifted and moved on the elbow joint. The extend- 

 ing activity of the muscles on this lever comes espe- 

 cially into play, as the leg pushes the weight forward. 

 This activity becomes, then, of the same importance 

 for the fore arm, as the united activity of the muscle« 

 of the hose and the extensors of the hock joint for 

 the hind legs, namely, as a pushing and elastic 

 power. For this reason has a long projection of the 

 elbow the same advantages of a long lever, as the 

 lever bone of the hock joint. A long projection of 

 the elbow has the further advantage of granting the 

 necessary space for the full development of the mus- 

 cles of the fore arm, which rest partly on the former, 

 and, in which case, the upper part of the fore arm,
