62 MATERIALS FOR A JIEMOIR OX 



The Gallop. (See pp. 41, 53.) 



In series 632, the frout legs are "on" and "off" equally, each 

 being "on" 2 and "off" 10 in a series of 12. While the hind 

 legs are unequal, the left leg being "on" 5 and "off" 7, the right 

 is "on" 4 and "off" 8. 



In series 631, the fore feet are equal, being 3 "on" and 9 "off;" 

 the hind legs are again unequal, the left being " on" 3 and the 

 rig-ht 4. 



In series 633, the feet are all moving equally. Each foot is 

 " on" 3 and " off" 9. 



It will be seen that the fore feet move evenly for the front, and 

 in two of the three series twice unevenly and once evenly. 



When the horse is going at a moderate rate of speed the greatest 

 distance between any two of the impressions made on yielding soil 

 answers to the interval between the anterior of the impressions of 

 the hind feet and the first of the fore feet. When the animal is 

 going at a high rate of speed the greatest distance is between the 

 fore foot by which he leaves the ground on the leap and the hind 

 foot by which he alights. 



In the canter the impressions made by the hind feet on the soil 

 are in the same relative positions as in the gallop, — i.e., they follow 

 one another at wide intervals. The fore feet, however, yield im- 

 pressions which lie close alongside one another, — at about the 

 same place. 



In contrasting the two gait's, it is evident that in the canter the 

 hind feet act with such ineffective energy that the fore feet are 

 compelled to follow each other in rapid succession to prevent the 

 fore part of the trunk from falling. In the gallop the momentum 

 of the body carries it easily over both fore legs, which can leisurely 

 in succession act the part of vaulting-poles. 



The gallop as well as other gaits show irregularity. 



In series 680, oryx, this is reduced to a minimum. In this in- 

 teresting series all the limbs excepting the right fore limb are "on" 

 and " off" equally. Even in the right fore limb the departure 

 from uniformity is not great, the order being "on" 4 and "off" 6. 



In the fallow deer (series 682) the limb-movements are uniformly 

 " on" 5 and " off" 11, except the left hind foot, which stands " on" 

 6 and "off" 19.
