64 MATERIALS FOR A MEMOIR ON 



In the walk of the buffalo (series 699) the order is as follows : 

 Rh "on" 18, "off" 6 ; Rf "on" 16, "off" 8 ; Lh "on" 10, "off" 

 14; Lf "on" 15, "off "9. ■ 



Nothing here is synchronous ; the greatest discrepancy is seen 

 in the diagonal and the least in the lateral feet. 



In the ox (series 670) the difference between the two fore legs 

 alone is great: Rf "on" 11, "off" 1 ; Lf "on" 8, "off" 4. 



In the cat (series 720): Rf "off" 20, "on" 4; Lf "off" 15, 

 "on" 9; "Rh "on" 9, "off" 15; Lh "on" 9, "off" 15. 



Here all feet are acting synchronously excepting Rf. Between 

 the fore limbs there is the most marked difference. The left fore 

 limb remains on the ground over twice as long as its fellow. 



In the horse (series 576) the diagonal Rf and Lh are " on" 8, 

 "off" 4; while the opposed diagonal is Rh "on" 11, "off" 11 ; 

 andLf "on" 6, and "off" 6. 



The walk in the raccoon (series 744) shows that the fore leg 

 moves slower than the hind leg. When the momentum of the 

 animal is increased the fore leg attains the same speed of rapid 

 change as the hind. 



The rate of the "on" and "off" of the fore feet is | to i, while 

 in the horse (series 579) the rate is f " on" to ^ " off." 



The left fore foot is "on" the ground in 1, 2, 3, 10, 11, 12, 13, 

 14, 20, 21, 22, 23, = 12. 



The left fore foot is " off" the ground in 4, 5, 6, 7, 8, 9, 15, 

 16, 17, 18, 19, 24, = 12. 



The left hind limb is "on" in 1, 8, 9, 10, 11, 17, 18, 19, = 8. 



It is "off" in 2, 3, 4, 5, 6, 7, 12, 13, 14, 15, 16, 20, 21, 22, 

 23, 24, = 16. 



Thus the left fore foot is in the act of supporting and propel- 

 ling the body for the same length of time as it is engaged in pre- 

 paring for a second stoke. In the left hind foot the time of the 

 foot when engaged in support or propulsion is but one-half that 

 6f the time when it is engaged in the air. 



Combinations in the Walk. 



Out of the number of combinations which it is possible to 

 secure from the feet when on the ground the following is the 

 arrangement most frequently seen in the act of walking: Two 

 hind feet alone ; two fore feet alone ; two hind feet and two fore
