PROGRESSION ON THE LAND.

bound would be succeeded by a halt, or dead point, that could 

 not fail seriously to compromise continuous forward motion. 

 In the gallop, as in the slower movements, the horse has 

 never less than two feet on the ground at any instant of time, 

 no two of the four feet being in exactly the same position. 



Mr. Gamgee, who has studied the movements of the horse 

 very carefully, has given diagrams of the walk, trot, and 

 gallop, drawn to a scale of the feet of a two-year-old colt in 

 training, which had been walked, trotted, and galloped over 

 the ground for the purpose. The point he sought to deter- 

 mine was the exact distance through which each foot was 

 carried from the place where it Avas lifted to that where it 

 alighted. The diagrams are reproduced at figures 21, 22, and 

 23. In figure 23 I have added a continuous waved line to 

 indicate the alternating movements of the extremities ; Mr. 

 Gamgee at the time he wrote ^ being, Jie informs me, unac- 

 quainted with the figure-of-8 theory of animal progression as 

 subsequently developed by me. Compare fig. 23 with figs. 

 18 and 19, pp. 37 and 39 ; with fig. 50, p. 97 ; and with figs.

In examining figures 21, 22, and 23, the reader will do 

 well to remember that the near fore and hind feet of a horse 

 are the left fore and hind feet ; the off fore and hind feet 

 being the right fore and hind feet. The terms near and ojf
