1 8 THE GALLOP. 



were retained because they show the horse in slightly 

 different stages of the same action ; but they were not 

 strongly enough marked in points of distinction to be 

 introduced among the nine others, by which the gallop 

 was sufficiently explained. 



The velocity might be great enough to have the mass 

 transferred from the left fore-leg to the right fore-leg, 

 without the intervention of the right hind-leg, and the 

 pace still be the gallop, provided that the horse was so 

 collected that he had planted the right hind-leg and the 

 left fore-leg at the same time. But at the low speed in 

 which I rode the horse in my experiment not greater 

 than six miles an hour the momentum was not sufficient 

 to give me an example of that position. 



THE RUN AND THE GALLOP CONTRASTED. 



If we compare the horse in the corresponding attitudes 

 of the two paces, as exhibited by the camera, we shall 

 see how widely they vary, both in regard to the general 

 appearance of the animal, and with reference to the actual 

 motions. 



In the disconnected state in which the horse performs 

 the run, it would be impossible for him to have three feet 

 upon the ground at any time, or at any rate of speed, but
