curves of pressure of the four feet, drawn at two different levels : the 

 uppermost are the curves of the anterior limbs ; those below, of the 

 posterior limbs. In each series the curves of the left foot are drawn 

 with dotted lines, those of the right with full lines. 



The moment when the curve begins its rise represents the com- 

 mencement of the pressure of the foot on the ground ; the point at 

 which the curve begins to descend represents the moment when the 

 rise of the foot commences. It is seen from these tracings that the 

 feet AG and PD, left fore-foot and right hind-foot, strike the ground 

 at the same time. The simultaneous lowering of the curves of the 

 two feet shows that they also rise from the ground simultaneously.
