NOTATION OF THE PACES OF THE HORSE. 



Fig. i6g. — The Leap [see Figs. 138 to 151 



this figure more graphic, I have used plain rectangles to mark the supports 

 of the left foot, and shaded ones, those of the right foot. If we desire to 

 represent the ordinary walk of a man in the same manner, we shall be con- 

 fronted with the difficulty that, as both feet are on the ground at certain 

 periods of this pace, the rectangles would naturally have to overlap each 

 other. We may, however, get over it by placing the diagrammatic prints of, 

 say, the left foot on a line above those of the right foot. In this manner, in 

 order to represent the run, we would place these prints as they are shown in 

 Fig. 155; not as in Fig. 154. We may indicate the walk by Fig. 156, in 

 which I have assumed that both feet are on the ground for one-sixth of 

 the period of support of each foot. 



We must remember that these scales or notations give us only the order 

 of succession of the feet, and their respective and proportionate periods of 

 support and suspension ; but they do not furnish us with a clue to the 

 speed of any particular pace, except, that when there is a period of suspen- 

 sion ; the longer it is, the greater, as a rule, will be the speed. 



To construct the respective notation of the various paces of the horse, we 

 may employ the rectangles of Fig. 154 for the fore legs, and may use similar 

 ones, placed underneath them, for the hind legs. Thus, Fig. 158 will give us 

 the scale of the trot as shown by Figs. 39 to 42. 



My readers will notice that the dotted lines on Fig. 159 mark the 

 respective moments at which the horse assumed the positions depicted in 

 Figs. 43, 45, 46, and 47. In the remaining notations in this chapter I 

 have similarly marked the connections between these scales and the corre- 

 sponding figures in Chapters XII. and XIII.
