He won a remarkable series of victories between his first race at 

 Brighton Beach, July 14, 1904, as a two-year old, and his untimely 

 death at four years (June 17, 1906). The skeleton and its mounting 

 was presented to the Museum by the late James R. Keene. 



SKELETON OF SYSONBY," PRESENTED BY JAMES E. KEENE 



BEING MOUNTED TO SHOW A PHASE IN THE 



STRIDE OF THE E [INNING HORSE 



This mount is based on studies by S. H. Chubb made from direct 

 observation and from the instantaneous photographs of Muybridge, 

 Hemment and Chubb. The position is that taken the moment after 

 the right fore foot has left the ground, and the right "knee," or carpus, 

 is beginning to bend; the succeeding foot-falls in order are the left 

 hind foot, the right hind foot, the left fore foot, and the right fore foot. 

 The full length of one complete stride is about 26 feet. 



SYSONBY. Motion of the Hip and Shoulder and Limbs. At this 

 instant the hind quarters and limbs are lifted perceptibly higher than 

 the shoulders, and from a rear view it will be seen that while the hind 

 feet are thrust forward at this great height from the ground, they are 

 widely separated from each other so as to avoid striking the fore legs. 

 A moment later the shoulders will be lifted by the push of the fore foot 

 higher than the hind quarters, then the hind feet will move toward 

 the median line and strike the ground and the fore feet will move 

 forward out of the way of the hind.
