Oj the trot.—The notation of the trot is obtained by a more decided anticipation of the hinder limbs, each of which will have entirely completed its pressure on the ground, and begun to rise at the moment when the fore-leg on the same side has completed its stroke. Fig. 40 expresses the absolute alternation of the two persons supposed to be Fig. 40.—Notation of a horse's trot Authors agree also on this point, that in the trot, the limbs which act together are associated in diagonal pairs. The ear perceives but two sounds of the hoofs, as in the amble, but with this difference, that it is always a right and left foot together, and not two feet on the same side, which produce each sound. The notation also shows that the pressure of the body on the ground is always diagonal. What it does not express is, that between successive pressures, the body of the animal is, for an instant, suspended in the air. This suspension arises from the fact that the trot is not a walking^ but a running pace, and that to represent it faithfully we must place together two notations similar to that which is represented in fig. 34. We have designedly omitted the time of suspension in the former notation; it would have rendered a difficult subject still more complicated. Besides, this suspension does not always take place; certain horses have a low trot, which has nothing to characterise it except its rhythm in double time and the diagonal impacts of the feet. We will not fatigue the reader by detailing the definition of all the paces admitted by different authors. We shall merely present in a synoptical table the series of notations which correspond with them. In this table (fig. 41) it is seen, that all the lower paces may be considered as derived.
