or otlier of the notations in the tal>le of regular paces. A 

 scale, marked 1, 2, ;!. I. &c., np to which we can bring the 

 mark representing the left liintler impact, allows us to form 

 without hesitation any notation whatever. 



To form tin- notations of the gallop, it is necessary to shift 

 the slides corresponding with the fore-legs, so as to make 

 them encroach ou each otlier as is seeu in notation, fig. 69.

The notation rule is thus used. When we are sure that 

 the pace is regular, it is sufficient, for instance, to examine 

 the impacts of the two right feet, in order to construct the 

 whole notation. According as the hinder impact is synchro- 

 nous with that in front, or precedes it hy a quarter, half, 

 three-quarters, or the whole of the duration of a pressure, we 

 place the two lower slides in the position which they ought to 

 occupy, and the notation is thus simplv constructed; it shows 

 the rhythms of the impacts, the duration of the lateral and 

 diagonal pressures, &<. The construction of the various 

 paces of the gallop is effected in the same manner. 



The artist who wishes to represent a horse at any instant 

 of a particular pace, can thus easily determine the correspond- 

 ing attitude. He forms on his rule the notation of the pace 

 of the horse which is to lie represented. Then, on the length 

 which corresponds with the extent of a single pace in this 

 notation, he erects a perpendicular line at any point. This 

 line corresponds with a certain instant of the pace. Thus, as 

 he can trace, on the length corresponding with a single pace.
