CHANGE 
The precise methods by which changes from the walk 
to the trot, or from the trot to the gallop, are effected, 
have always been disputable subjects. The former change 
is demonstrated in series 72, the latter in series 73. In 
each of these the horses were dragging a racing sulky, 
which has been obliterated to facilitate examination ; with 
the same object in view dots have been made in proximity 
to the right pasterns. 
Series 74 is a change from the rack to the gallop, 
75 illustrates some phases attained by a thorough-bred 
CO 
OF GAIT. 
Kentucky mare, after landing from a jump of twenty-six 
feet three inches, by actual measurement, over a bar one 
and a half yards high. Phases 23 and 24 are interesting, 
and suggest the Byzantine treatment of the gallop. 
All of these changes were accidental, and therefore 
perfectly natural; 72, 73, and 75 have been filled in 
to make them more distinct for study, the exact outlines 
having been carefully followed. Series 74 remains in the 
precise condition of the original negative, with all its faults. 
These four seriates were photographed in 1879.
