The exterior of the horse . them vary-ing aspects. It is greatest in the long trot, medium in the ordinary,and very little marked in the short. According to the height to whichthe body is raised, it renders the gait high or low. It is, in general,proportional to the speed employed and the vigor of the animal. When the velocity of the trot is carried to the extreme, the syn-chronism of the diagonal beats is seen to disappear; the latter areslightly disassociated, and this all the more as the hind-foot reachesfarther beyond the fore-foot of the same side. The amplitude of thesteps then reaches its highest limits. This is the beginning of a newvariety, the broken trot, trot of the hippodrome or the race-course, whichthe English, on account of its velocity, call the flying trot. AVe willstudy it presently. Kinematic Analysis of the Play of the Members in the Trot.—1st. Anterior Member.—The period of dispersion of forces, 0 to 2, verymarked, is manifestedi above all, during the contact with the ground, as deduced.

Marey and Pages (Fig 207, A), by the sudden andforcible descent of the fetlock, which is also perceived by the carpus and theelbow, although less sensibly by the latter. The curve of the withers is greatlydepressed in its middle, in consequence of the flexion of the angle of theshoulder. During the elevation, S, the trajectory of the withers also offers a curve in itsmiddle, a marked inflection, due to the shortening of the opposite member, nowin its contact, which weakens, in its turn, the concussion of the body upon theground. The trajectories of the fetlock and the knee, sensibly parallel, forcibly 33 514 THE EXTERIOR OF THE HORSE. ascend (the fetlock first) during the shortening of the member, to descend simul-taneously when the latter elongates and prepares to res
