PvEF LECTIONS. 



N refleding upon the various motions a 

 horfe makes, and upon the flrudture of his 

 foot, we cannot be furprifed to find this part 

 liable to fo many accidents. Experience llie^ys 

 Ks that for one horfe who is lamed in the 

 haunch or fhoulder, an hundred have it in the 

 foot, and that the know^ledge of this part me- 

 rits all our attention : I am of opinion thefe ac- 

 cidents happen chiefly to draught-horfes, and 

 not to thofe of the faddle ; I alfo think that 

 it is the different attitudes of a horfe's foot over- 

 charged at the fame time with the weight of his 

 body, that caufe the different fra6lures of the 

 coronary and nut-bones ^ for when the foot has 

 not a diredl pofition, the joints are twifted, as 

 when a horfe treads upon the point or toe of 

 the hoof, the upper and inner part of the coro- 

 nary-bone, which is in an oblique pofition, 

 prefTed in that ftate by the burthen of his own 

 body, is forced to yield on one fide, and rife on 

 the other^L its lower and back part, which now 

 rifes, drives the nut- bone againfl the TendoAchil - 

 lis which fuftains it, the tendon preiTes in its 

 turn againft the flelhy fole, which is alfo com- 

 prefied againfl the horny fole, which is its 



point
