the BLOOD, what the neceffary evacuations 

 bf dung and urine take from the accumu-

 ternatural proportion, mult, by its com- 

 puliive retention, acquire a degree of putrid 

 or acrimonious morbidity inevitably pro- 

 ducing difeafe. Thefe morbid attacks adt 

 differently upon different fubjeds, accord- 

 ing to their ftate or tendency, at the time

 rupt or infectious influence ; difplaying it- 

 felf in fuch w^ay as is moft applicable to 

 the conftitutional predominance of difeafe 

 in the horfe previous to the leaft trait of 

 difcovery. 



I fhall, in compliance with my promife in 

 the introductory part of this work, forbear 

 to lead the reader farther into a tedious 

 train of remote medical refearches, but re- 

 fer him to the different difquilitions of the 

 former volume for any gratification he may 

 wiflr to obtain ; letting it fuffice to obferve^ 

 that from fuch original caufe may arife 

 the various diflrelling difquietudes io re- 

 peatedly enumerated, as fwelled legs, cracked 



P ^ heels.
