 fetlock and the knee or the hock (Figs. 222 and 223, A).

During the phase of contact, the curves of the articulations of the fore-mem- 

 bers become progressively convex, in consequence of the rotation of the phalan- 

 gal lever which raises the articular centres, particularly the two inferior, fetlock

and carpus. Towards its termination, the curves descend again under the influence 

 of a slight flexion of the knee. In the posterior members, they undergo almost 

 analogous modifications.
