A NEW SYSTEM 



CHAP. XIII. 



Of the Aids of the Body.

 JL already proved, in their mutual Harmony and Cor- 

 refpondence, for without this Agreement, they muft be 

 always ineffecSlual ; becaufe the Horfe can never work with

 demonftrate, that the Aids of the Body contribute, and 

 are even capable of themielves, from the Principles of 

 Geometry, to make us acquire the Union of the Aids of the 

 Hand and Leg ; and if fo, we {hall be obliged to own the 

 Conclufion, that they are to be prefer'd to all the reft. 



The Juftnefs of the Aids of the Body .depends upon 

 the Seat of the Horfeman. — Till he is arrived at the Point 

 of being able to iit down clofc and firm in his Saddle, fo 

 as to be immoveable in it, it v/ould be vain to expedt he 

 fhould be able to manage a Horfe ; becaufe, belides that he 

 would be incapable of feeling his Motions, he would not be 

 poiTeffed of that Equilibre and Firmnefs of Scat, which is 

 the Charaderiftic of a Horfeman. I would define the Equi- 

 libre to be, when the Horfeman fits upon his Twift^
