on a pavement, but it is upon their form and the 

 manner of fetting them on, that not only the 

 prefervation of the foot, but alfo the fafety of 

 their legs, and the eafe of their motions depend. 



And in effect, the more eafy our fhoes fet 

 upon us, the more active we are ; fo a large, 

 long, thick Ihoe ought to have the fame effecl; 

 upon horfes, that wooden fhoes have upon us, 

 that is, make them heavy, unweildy, and 

 hobling. 



Let us now obferve the going, as well as the 

 external and internal ftructure of a horfe's foot. 



The horfe who draws, preffes firft upon the 

 toe, then fuccefiively upon the fides, to eafe 

 the toe -, and then the horfe's heel yields upon 

 the heel of the ihoe, from which it immediately 

 rifes again. 



The laddie or pack-horfe places the toe but 

 lightly ; which is the only difference in their 

 going ; fo that in both cafes, the point of fup- 

 port is fixed neither upon the heel nor toe, but 

 between both ; which it is eafy to demonftrate 

 anatomically, figure the firft, plate III. 



The canon- bone 3. preffes upon the paftern 4. 

 this upon the coronary 5. the coronary upon 

 the coffin or foot- bone 6. and upon the nut- 

 bone 3. fig. 2. 



By this difpofition of the bones, we mould 

 obferve two efiential things, which lay open 

 the faults in the prefent method of fhoeing, 

 and point out the means of being able to re-
