took place in the same time. We there see also a similar 

 arrangement of the gray bands, which has a similar signifi- 

 cance for the left fore and hind feet. 



And if we recollect the three phases of pressure (see 

 p. 289, and Figs. 121, 122), we shall comprehend, in 

 looking at the diagrams, that, at the initial stage (A), 

 the limbs are commencing their pressure, and are oblique 

 downwards and forwards ; that afterwards (B) the two 

 limbs are vertical, since they are at the middle of the 

 pressure stage ; and that finally (C) they are oblique 

 downwards and backwards, for it is then the termination 

 of their pressure (Fig. 124), 



During the time that the right limbs are pressing 

 ■(notation, white bands) the left limbs are raised ; after-

 (after Professor Marey). 



wards these latter take up the pressure (gray bands), and 

 then the right limbs are raised in their turn. 



During the pace of ambling the weight of the body, which 

 is wholly sustained by the limbs of one side only, is not 

 in equilibrium, so that the limbs which are raised return 

 by a brisk movement to the position of support in order to 

 re-establish it. 



The Trot.— We have just seen that, in order to represent 

 the amble, the two marchers moved their right limbs 

 simultaneously, and then their left ones. 



Let us suppose now that the hinder man anticipated 

 by half a pace the movement of the front one, then 

 wiU be found realized the association and the nature 

 of the displacements of the hmbs during the pace of the 

 trot. 



By this anticipation of a half-step (we have defined, 

 p. 288, what is to be understood by the word step), it
