Fig. 375 will be as the length of ^ 6 is to that of a c. 

 Or, if we term the forward propulsion in Fig. 373, P, 

 and that in Fig. 375, P^, we shall have P^ =P x ,^. 



In this question, we need take into account only the 

 direction of the fore pasterns, because the mechanical con- 

 struction of the joints of the stifle and hock causes the hind

 line, namely, that of forward progression ; and the same 

 remark applies to human sprinters and fast walkers.
