THE GALLOP. ir 



Plate I.). The horse leaves the ground from one of his 

 fore-feet, receives the weight upon the diagonally dis- 

 posed hind-foot (planted four feet or more in advance of 

 the spot just left by its predecessor), divides the burden 

 between this and the other hind-foot, takes the mass upon 

 the last-mentioned, then divides the weight with the 

 diagonally disposed fore-foot, takes the mass upon this 

 fore-foot, to afterwards divide the weight between that and 

 the first-used fore-foot, and from the last named leaves 

 the ground, by aid of the momentum, in a new stride. 



Each leg has in turn received the whole weight, and 

 the burden has been borne by the two hind-legs, a hind- 

 leg and a fore-leg, and the two fore-legs. The mass has 

 been carried along as if over a series of crutches, the 

 succession slightly broken at the beginning of each 

 stride. 



When the horse passes the weight from one fore-leg 

 to the other (see figure i, Plate I.), he is very much ex- 

 tended. After he leaves the ground the hind-legs are 

 carried under the body to receive the weight under the 

 centres of gravity and of motion, and the horse is in a 

 very cramped position (see figure 8, Plate I.). 



I marked down the footprints of the running horses as 

 they were represented in Muybridge's photographs, and 

 compared them with the tracks made by galloping horses
