1M, NATURAL HISTORY. 



three intervals, of which, the first and last are shorter 

 than the middle one. In the trot there are but two 

 times in the movement ; if the right fore leg goes off 

 first, the left hind leg moves at the same time, and 

 without any interval between the motion of the one and 

 the motion of the other ; the left fore leg moves also 

 at the same time with, the fight hind one. 



In the gallop there is usually three times ; but as 

 in this movement there is a kind of leaping, the interior 

 parts of the horse do not move of themselves, but are 

 driven away by the strength of the haunches and the 

 hinder parts. Thus, of the two fore legs, the right 

 ought to advance more forward than the left. The 

 left ought beforehand to rest on the ground to serve 

 as a point of rest for the sudden jirk which he takes. 

 Hence the left hind foot makes the first time of the 

 movement, and rests on the ground first ; then the 

 right hind leg is lifted up conjointly with the left fore 

 leg, and rest on the ground together. At length, the 

 right fore leg, which is raised an instant after the left 

 fore leg, and right hind one, rests on the ground last, 

 which makes the third time. Thus, in this movement 

 of the gallop, there are three timea and two intervals ; 

 and in the first of these intervals, when the movement 

 is made with haste, there is an instant when the four 

 legs are in the air at the same time, and when the 

 four shoes of the .horse may be seen at once. When 

 the horse has the haunches and the houghs supple, 

 and moves them with agility, the movement of the 

 gallop is more perfect, and the cadence is made in 

 four times : he then rests the left hind foot, which 

 shews the first time ; when the right hind foot falls 

 to the ground, and shews the second time, the left 

 fore footfalls a moment after, shewing the third time;
