ness. Dealers distinguish them by the term 

 buck-eyed, or moon-eyed, and generally 

 deem them unsound. But it would be just 

 as reasonable to deem a horse unsound, be- 

 cause, in his natural formation, he might 

 happen to be what is called over-hock'd ; a 

 form which, by experience, is well known to 

 be more subject to spavins and thorough 

 pins than any other. 



Running thrushes, or rotten frogs, are 

 considered by some as a mark of unsound- 

 ness, whilst the contrary opinion is held by 

 others ; yet, both a well-formed foot, and a 

 bad-formed foot, may be affected with run- 

 ning thrushes ; nor is lameness always a 

 consequence of this disease. 



A cough is frequently the forerunner of 

 what is termed broken wind, yet a horse 

 may cough, occasionally, for several years, 

 and not ultimately become unsound in his 

 wind. 



Splents, spavins, and curbs, are causes of 

 lameness, yet a horse may be aftected with 

 any of these excrescences, without being- 

 lame ; that is to say, the disease may re- 

 main inactive for a certain period, and not 

 be brought into action, except by peculiar 

 circumstances.
