in such a manner that the second beat of the former coincides with the 

 first beat of the latter (Figs. 236 and 237). 



It follows from this mode of association that instead of hearing four 

 beats during the duration of a complete step, as if each foot was placed 

 on the ground separately, only three are heard, in consequence of 

 the synchronism of the beats of the second contact. 



The anterior and the posterior members may combine their move- 

 ments after two different types : 



1st. When the anterior biped gallops in the same manner as the 

 posterior (Fig. 236), the second period of contact is produced by the 

 simultaneous diagonal beats which are interposed between the two other 

 diagonal disassociated beats. We propose to designate this type, in 

 order to distinguish it from the following, under the name of diagonal

gallop. It is that which is natural to the horse and other large do- 

 mestic quadrupeds. 



2d. If, conversely, the anterior biped gallops in a manner inverse to 

 that of the posterior (Fig. 237), there are two lateral simultaneous beats,
