If we accept the word time as meaning the number of separate steps in each stride of a pace, we may describe the walk as one of four time, the limbs moving one after another consecutively.

Commencing, for instance, with the left fore-leg, the movements will be in the following order: - 1, left fore; 2, right hind; 3, right fore; 4, left hind. Or, as frequently happens with the horse which has no military predilection for leading off with the left fore, but commences with any leg, according to convenience, suppose him to commence with the left hind-limb, the sequence will be - 1, left hind; 2, left fore; 3, right hind; 4, right fore. Each foot follows the one which precedes it in something like half the time it takes to make one step.

As a result of these movements, the order in which the body is supported by the several limbs is as follows: - 1, right pair; 2, right diagonals; 3, left pair; 4, left diagonals (Plate LVII).



The lower row of figures shows, from right to left, the various positions of the left fore-foot in its forward movement.
