PLATE XV. 



FIG. 1 represents the horse in the canter, in which 

 pace his legs describe a rhomboidul qua- 

 drangle, A, B, C, D. 



Fig, 2 represents the gallop. Letter A marks the 

 spots which the hind feet occupied before 

 they quitted the groiuid. Letter B marks 

 the spots upon which the hind feet will 

 alight when they have completed their 

 action; the distance between A and B, 

 therefore, gives the length of ground which 

 is passed over at each stroke.
