If we note in this manner the rhythms of all the juices used 

 by man, \ve shall ohtain a synoptical table which will much 

 facilitate tin- coiiipan.-ou of these varied rhythms. Fig-. 25 

 represents the syin>j>ti<-nl ni>t<iti<m of the four kinds of progres- 

 sion, or paces, which are regularly rhythmical, and in which 

 the two feet act alternately. 



Line 1 represents the nutation <>j the rhythm of the ivalkin-j 

 /"i'. This is the principle of the representation. 



The pressure of the right foot on the ground is represented 

 by a thick white stroke, a sort of rectangle, the length of 

 which corresponds with the duration of that pressure. For 

 the left foot there is a greyish rectangle shaded with oblique 

 lines. 



These alternations of grey and white express, by their suc- 

 cession, that in walking the pressure of one foot succeed^ the 

 other without allowing any interval between the two. 



Fio. 35. Synoptical notation of the four kinds of progression used by num. 



Lino 2 is the notation which corresponds with the ascent <>f 

 it staircase. It is seen, agreeably with what has been already 

 explained (fig. 29), that the step-curves encroach on each 

 other, and that, consequently, the body during an instant rests 

 on b:>th leet at Once. 



Line ;; corresponds with the rhythm f runniiii/. After a 

 fihorter step-curve of the right foot than in the walking pace, 

 an interval is teen which corresponds with the suspension of 

 the body; then a short impulse of the left foot, followed by a 

 fresh suspension, and so on continually. 



Line 1 answers to a more ni/ii,l nil,' <//' niiiiiin;/. AVe find in 

 it a shorter duration of the pressures, a longer time of the
