station, fulfil a role, if not equal, at least identical, that of supporting 

 the body-weight ; it is therefore but logical that they obey the same 

 principles of equilibrium. 



Let us pass in review, now, the vices of the axes of the posterior 

 members. 



A vertical line, cd (Fig. 163 [1]), passing through the middle, r, of 

 the leg, should pass, above, through the centre of posterior suspension, c 

 (coxo-femoral articulation), intersect, below, the middle of the hoof, d,

and remain equidistant from the vertical lines op, mn, lowered from the 

 patella and the angle of the buttock, the latter tangent to the point of 

 the hock and to the fetlock. 



If the member, as a whole, is placed in front of this line cd, the 

 horse is said to be under himself behind (Fig. 163 [2]). 



If, on the contrary, it is situated behind, the horse is said to be 

 camped behind (Fig. 163 [3]). 



Finally, if the deviation only takes place from the fetlock down, 

 the subject is called : 



Long- and low-jointed when the middle of the foot, d, approaches 

 the vertical line op.
