becomes broader, and the weight of the latter grows 

 ■larger. The fastest, and so very shoulder free raco- 

 liorses, have the thinnest necks. 



The elboio joint connects the arm bone with the 

 yore arm. This latter consists of the fore arm bone 

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

 called the lever of the elbow, 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 muscles 

 of the hose and the extensors of the hock joint for 

 the hiud legs, namely, as a pushing and elastic 

 ])iiwer. 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 fiiithcr advantage of granting the 

 necessary space for Wu\ full develo]nnentof the mus- 

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