CHAPTER XI. 



WIND. 



If the lungs of horses are sound, their inspiration 

 and expiration are equal, and forms what is called 

 " their respiration," or breathing. Race horses 

 that have large circular chests, formed by their 

 ribs being well arched over their hearts, and that 

 are moderately straight in their carcasses, have 

 mostly good winds; indeed, it is principally from 

 the circumstance of the chests of well formed, 

 thorough-bred horses having a more spacious 

 capacity; that their wind is brought to the highest 

 degree of excellence, or rather that it may soon 

 be brought to great perfection by the manage- 

 ment and exercise they have to undergo in train- 

 ing, which enables them to run on for long 

 lengths with comparative ease to themselves.
