with the off fore, as in Fig. 200, (1), the next leg to move 

 is the near hind (2). This is followed by the near fore, and 

 lastly by the off hind. There are four distinct movements in 

 each stride of the walk, and as there are two strides to a complete 

 advance of the body — viz., one on the near and one on the off 

 side — there are altogether eight movements. The best method 

 of conveying the eight movements of the walk is by means of 

 a system of notation,* as in Fig. 201. This shows that in the

walk the limbs on the ground at any one time are three, followed 

 by two, followed by three, "and so on. In Fig. 200, (1) shows 

 that the support may be by means of one fore and both hind 

 legs, or one fore and one hind diagonal, as in (2), or both fore 

 and one hind, as in (3), or one fore and one hind lateral, as in (4). 

 There may be slight variations in the walk, such, for instance, 

 as in the case of a draught-horse loaded or a horse out grazing ; 

 but in the true walk the broad principles above described are 



* In the diagrams of notation the narrow end of the figure represents the 

 head ; the spots represent the legs on the ground at any one moment ; 

 they do not, of course, represent the relative position of these limbs to 

 each other.
