382 THE EXTERIOR OF THE HORSE. 



VERTICAL HEIGHT OF THE ANTERIOR MEMBER CALCULATED FROM THE NOR- 

 MAL LENGTH OF THE SEGMENTS AND THE REAL ARTICULAR ANGLES 

 WHICH THEY FORM WITH EACH OTHER. 



Shoulder (a) 0.a5507 m. 



Arm (6) 0.25394 m. 



Forearm 0,36000 m. 



Carpus 0.05000 m. 



Metacarpus 0.24000 m. 



Phalanges (c) 0.14722 m. 



Cartilage of prolongation, shoe, hoof, etc 0.12000 m. 



Total of the member ' . . . . 1.52623 m. 



Same height calculated from the figures of M. Lemoigne> 1.55316 m. 



The same calculations applied to the posterior member (Fig. 140) give for 

 the values of a, b, c, d: 



a = 0.26 m. sin. 35° = 0.14912 m. 

 b = 0.39 m. sin. 80° = 0.38407 m. 

 c = 0.36 m. sin. 70° = 0.33828 m. 

 d = 0.17 m. .sin. 65° = 0.15407 m. 



VERTICAL HEIGHT OF THE POSTERIOR MEMBER CALCULATED FROM THE 

 NORMAL LENGTH AND INCLINATION OF THE SEGMENTS. 



Ilium (a) 0.14912 m. 



Thigh (6) 0.38407 m. 



Leg (c) 0.33828 m. 



Tarsus 0.08000 m. 



Metatarsus 0.28000 m. 



Digital region (d) 0.15407 m. 



Vertical distance between the summit of the croup and that of 

 the haunch ( we have intentionally represented it as very 



small) 0.02000 m. 



Thickness of the interarticular menisci, cartilages, skin, shoe, 



hoof, etc 0.05000 m. 



Total of the member 1.45554 m. 



Same height calculated from the figures of M. Lemoigne « . . . . 1.44448 m. 



Thus, by taking M. Lemoigne's measurements as well as our own 

 as a base, we succeed in reconstructing the members with their normal 

 medium height, Avhich proves the relative precision of our observa- 

 tions. 



Influence of the Inclinations of the Bones upon Speed. 

 — The degree of opening of the locomotory angles of the horse have a 

 marked influence upon the development of speed. With regard to the 

 superior regions of the members, we have not failed to mention and to 

 indicate, for each bone, the value of the inclination which it should 



1 Here the shoulder and the phalanges are a little less inclined than they should be, which 

 makes the member a little longer. 



« Here the femur and the tibia are a little more inclined than they should be, which makes 

 the member a little shorter.
