SUPERIOR FACE OF THE BODY.

BR, indicating the direction of the force of gravity, is exerted at the 

 end of the cervical lever at a very acute angle, an incidence which 

 diminishes the intensity of the force of gravity. This explains why 

 horses carrying the neck in this position are not hard-mouthed; the

head seems to weigh less at the end of the cervical stalk, in conse- 

 quence of the slightly-perpendicular incidence of the line of gravita- 

 tion. 



Finally, we call attention to the favorable insertion of the extensor 

 muscles, Bm, which are in excellent condition to resist the weight of 

 the head and to carry it backward in order to give freedom to the 

 action of the anterior limbs. Horses with necks thus formed are well 

 qualified for all the brilliant movements of tossing and balancing the 

 head in the riding-school and in the parade.

 are deficient in energy, in the common races, and in those which are
