OF THE GALLOP. 



SEVERAL different paces, the common character of which is 

 Unit irregular impacts return at regular intervals, are compre- 

 hended under this name. Most of the writers distinguish 

 three kinds of gallop by the rhythm of the impacts, nud 

 name them, according to this rhythm, gallop in tiro, three, 

 iiwl/r time. The most ordinary hind is the gallop in three- 

 time ; this we shall study in the first place. 



Experiments on the gallop. Fig- 55 has heen obtained from 

 a horse which galloped in three-time. At first sight, tho 

 notation of this pace reminds us of that which wo have 

 represented when speaking of human gallop (fig. 36, p. 13-1), 

 a pace used by children when " playing at horses." It 

 appears that the notation of the horse's gnllop has been 

 obtained by placing one over another two of these notations 

 of tho biped gallop; so that, in fact, the comparison used by 

 Duges is perfectly just, even \\lien it is applied to the gallop. 



Analysis of the tracing. At the commencement of the figure, 

 the animal is suspended above tho ground ; then comes tho 

 impact P O, which announces that the left hind-foot touches 

 the ground. This is the foot diagonally opposed to that which 

 the horse places forward in the gallop, and whose impact A D 

 will be produced the last. Between these two impacts, and 

 distinctly in the middle of the interval which separates them, 

 comes the simultaneous impact of tho two feet forming the
